Pairing nuts and dried fruit for cardiometabolic health
Nutrition Journal volume 15, Article number: 23 (2016)
Certain dietary patterns, in which fruits and nuts are featured prominently, reduce risk of diabetes and cardiovascular disease. However, estimated fruit consumption historically in the U.S. has been lower than recommendations. Dried fruit intake is even lower with only about 6.9 % of the adult population reporting any consumption. The 2015 Dietary Guidelines Advisory Committee identified a gap between recommended fruit and vegetable intakes and the amount the population consumes. Even fewer Americans consume tree nuts, which are a nutrient-dense food, rich in bioactive compounds and healthy fatty acids. Consumption of fruits and nuts has been associated with reduced risk of cardiometabolic disease. An estimated 5.5 to 8.4 % of U.S. adults consume tree nuts and/or tree nut butter. This review examines the potential of pairing nuts and dried fruit to reduce cardiometabolic risk factors and focuses on emerging data on raisins and pistachios as representative of each food category. Evidence suggests that increasing consumption of both could help improve Americans’ nutritional status and reduce the risk of chronic diseases.
It is well established that certain dietary patterns decrease disease risk and benefit the management of diabetes and cardiovascular disease [1–3]. A substantial body of research demonstrates that diets rich in fruits and vegetables can reduce the risk of overweight and obesity, cardiovascular disease, type 2 diabetes and hypertension [4, 5]. Fruit and vegetable intakes are, in fact, the only dietary characteristic consistently associated with every conclusion statement across health outcomes in the 2015 U.S. Dietary Guidelines Advisory Committee (DGAC) report . Despite the overwhelming evidence of the health benefits associated with consuming fruits and vegetables, the DGAC identified a large gap between recommended fruit and vegetable intakes and the average amounts the population consumes . While the role of dried fruit in health is less well studied, health agencies around the world recommend them as a convenient way to incorporate more fruit into the diet.
The health benefits of tree nuts in relation to cardiovascular disease risk reduction have been widely studied [5–11]. More recently, nut consumption has also been associated with a lower risk of all cause, CVD, and cancer mortality [12–14]. In addition, the consumption of certain nuts, including pistachios, has been associated with improvements in the regulation of blood glucose and insulin, markers of inflammation, endothelial function , and other related metabolic risk markers . Nuts and dried fruits are healthful foods because of their nutrient profiles. They provide dietary fiber, potassium (K) and a variety of health protective bioactive compounds. Nuts also are a source of protein and monounsaturated (MUFA) and polyunsaturated fatty acids (PUFA).
This review examines the role of dried fruits and nuts in supporting cardiometabolic health and reducing CVD disease risk. It addresses the contribution that tree nuts and dried fruit make to U.S. nutrient intake and diet quality; the beneficial effects of tree nuts on cardiometabolic risk factors; and the effect of dried fruits on glycemia, insulinemia, and metabolic risk factors. It focuses on emerging research with raisins, the most commonly consumed dried fruit, and pistachios as representatives of each food category.
Nutrient contribution of dried fruit and nuts and their effect on diet quality
Three healthy dietary patterns are recommended by the 2015 Dietary Guidelines for Americans—a Healthy US-style Pattern, a Healthy Vegetarian Pattern, and a Healthy Mediterranean-style pattern. Fruits, nuts, and seeds play a prominent role in all three of these food-based dietary patterns, which recommend between 2 and 2 ½ cup equivalents of fruit a day and 4-7 oz equivalents per week of nuts and seeds .
Fruit and dried fruit
Fruit consumption in the U.S. has been low historically and has changed little in recent years. Data from the Centers for Disease Control and Prevention (CDC) indicate that 39 % of adults consume fruit less than once per day  and in a state-by-state survey, no state met the fruit intake target . Children generally fare better with fruit intake, but not by much. Data from National Health and Nutrition Examination Survey (NHANES) 2003–2010 showed that while intake of fruit among children has improved slightly, the majority are still far from age-adjusted recommended intakes . The low intake of fruits and vegetables is a missed opportunity to add under-consumed nutrients to diets .
Traditional dried fruit (those with no sugar added, such as raisins, prunes, dates, and figs) have been a staple of Mediterranean diets, valued for their sweetness and long-term stability. Traditional dried fruit has a similar nutrient profile as the original food and, as a result, dried fruit is typically a good source of fiber and potassium (Table 1). The consumption of dried fruit today is even less than fresh or canned; about 6.9 % of the adult population consume dried fruit [20, 21]. In an analysis of NHANES data from 1999–2004, raisins were the most commonly consumed dried fruit. Because they are used throughout the food system in products such as breads, muffins, cookies and cereals, raisins are consumed 6 times more than other dried fruits. In this study, dried fruit consumers were defined as those consuming 1/8 cup-equivalent dried fruit per day or more. Compared with non-consumers, dried fruit consumers had significantly lower intakes of solid fats/alcohol and added sugars and higher intakes of vegetables, meat, and soy products. Average energy intake of dried fruit consumers was 1038 kJ higher per day than non-consumers, yet they had significantly lower weight, BMI, waist circumference, and subscapular skinfold measurements, even after adjusting for lifestyle measures such as physical activity, TV/computer use, and smoking . Additionally, adult dried fruit consumers had significantly higher intakes of fiber, vitamins A, C, E, thiamin, riboflavin, niacin, and folate. Vitamin B12 was the only vitamin that was not higher among dried fruit consumers . Consumers of dried fruit had significantly higher intakes of calcium, phosphorus, magnesium, iron, zinc, copper, and potassium and significantly lower intakes of sodium .
The researchers also examined the association between dried fruit intake and diet quality using the Healthy Eating Index -2005 (HEI 2005) . The HEI-2005 is an objective measure of diet quality developed and validated by the USDA. Dried fruit consumers had significantly higher total HEI 2005 scores (about 8 % higher) compared to non-consumers. As a group, dried fruit consumers also had significantly higher HEI component scores on fruit, dark green/orange vegetables and legumes, whole grains, milk, saturated fats, and empty calorie scores, compared to non-consumers.
Tree nuts have been consumed for thousands of years, providing a concentrated source of energy, nutrients, and bioactive compounds, including unsaturated fatty acids . While nutrient content varies among species, tree nuts generally are good to excellent sources of protein, dietary fiber, vitamins E and K, folate, magnesium, copper, and potassium and are rich in phytosterols and phenolic compounds (Table 2). Consumption of nuts is even less common than for fruit, with a small minority, about 6.8 % of the population, including nuts in their diets on a regular basis . Mixed nuts containing peanuts (which are technically legumes) are the most commonly consumed nuts, walnuts the least. A recent analysis of data from NHANES 2005–2010 examined the nutrient adequacy of more than 14,000 adult tree nut consumers vs non-consumers, excluding pregnant and lactating women . Tree nut consumers were identified as those consuming ≥ ¼ ounce/day. In this study, tree nut consumers were more likely to be non-Hispanic, older, have higher incomes, were less likely to smoke and were more physically active than non-consumers. Consumers of nuts also had significantly higher energy intakes, about 200 kcal more, on days that nuts were consumed, than non-consumers. It is interesting, however, that despite the significant increase in energy intake, there was no increase in BMI or waist circumference . While tree nuts are an energy-rich food, estimates are that 55–75 % of the energy consumed is offset by dietary compensation and another 10–15 % is not absorbed [25, 26].
The analysis of NHANES 2005–2010 data also found that fewer consumers of tree nuts and tree nut butters had usual intakes (UI) of vitamins A, E and C, folate, calcium, iron, magnesium, and zinc that were below the Estimated Average Requirement (EAR) . Consumers of tree nuts and tree nut butters were also more likely to have UIs above the Adequate Intakes (AIs) for dietary fiber and potassium. Only about 4 % of the non-consumer population achieved dietary fiber Adequate Intakes (AI) of 14 g per 1,000 per day, whereas among tree nut and nut butter consumers, almost one-third of the population reached the AI. The higher intake of fiber among nut consumers was of the same magnitude as for dried fruit consumers [21, 24]. Tree nut consumers also had a significantly higher potassium intake; 11.9 % were above the AI, compared to 1.9 % among non-consumers, though both groups remained well below the AI of 4,700 mg/day. Sodium intake was high in both groups. Diet quality, as measured by the HEI-2005, was significantly higher in tree nut consumers compared to non-consumers (Table 3). In addition, total fruit, dark green and orange vegetables, sodium and solid fat, alcohol and added sugars (SoFAAS) kilocalories component scores were higher in tree nut consumers than non-consumers.
Potential dietary benefits of pairing nuts and dried fruit
Nuts and dried fruit have a complementary portfolio of nutrients. There is a cultural tradition of pairing them as snacks or in prepared foods. Yet, no study has evaluated the impact of combining nuts and dried fruit on the nutritional quality of the diet. Table 3 shows the potential effect of pairing tree nuts and dried fruit on diet quality, by comparing the differences in HEI scores between each consumption group and the corresponding non-consumption group. While nuts and dried fruit consumers have similar increases in HEI scores over non-consumers, there is no complete overlap of these groups (shaded areas). Combining these foods may thus further increase HEI scores. This is important because small changes in the diet can have a significant impact on health. A study calculated the potential public health impact on CVD mortality of replacing a unhealthy snacks (e.g., crisps, candy, cakes) with healthy ones (e.g., fruits, dried fruits, unsalted nuts). They found that simply replacing one unhealthy snack per day with a healthy one might prevent approximately 6000 cases of CVD per year in the UK . The Baltimore Longitudinal Study on Aging reported that CHD was approximately 75 % lower among men with both low saturated fat intake and high fruit and vegetable intake. This combination was considerably more protective than each behavior alone .
Dried fruit and cardiometabolic health
The limited number of clinical studies on dried fruit and cardiometabolic health suggests that it can lower the postprandial insulin response, modulate sugar absorption (Glycemic Index), promote satiety, and have a beneficial effect on blood pressure (BP) [29, 30]. An analysis of three large prospective longitudinal cohort studies, the Nurses’ Health Study, the Nurses’ Health Study II and the Health Professionals Follow-up Study, with a total of more than 3 million person years, found that associations of fruit consumption with the risk of developing type 2 diabetes differed significantly among individual fruits . The results showed that each incremental intake of 3 servings a week of certain whole fruits, including grapes or raisins, dried plums, apples or pears, grapefruits, and blueberries, was associated with a significant reduction in risk of developing type 2 diabetes. Not all fruits were associated with a reduction in risk.
Like many fresh fruits, dried fruits have a low to moderate glycemic index (GI) and a single serving exerts a low glycemic load (GL) . The GI measures the blood-glucose-raising effect of an amount of a carbohydrate-containing food that provides 50 g of carbohydrates . The GL predicts the blood sugar response to a standard serving of a food . Diets with a low GL help manage blood sugar and lipid levels and may lower the risk of developing diabetes [35, 36]. The GI of raisins was first determined to be 64 ± 11 (glucose = 100) in a study with 6 healthy, non-diabetic individuals . A later study measured raisin GI and Insulin Index in 10 sedentary adults, 10 pre-diabetic individuals, and 11 endurance athletes . The GI was 49.4 ± 7.4, 49.6 ± 4.8, and 62.3 ± 4.8, respectively. The Insulin Index was correspondingly low as well. This is important because high fasting and/or postprandial insulin levels can increase cholesterol synthesis and impair fat mobilization from adipose tissue. In a more recent study, the GI, Insulin Index, and glycemic response of raisins was assessed in 10 healthy subjects . The GI was 49 ± 4 with a corresponding low Insulin Index. The study also showed that a serving of raisins (28 g) exerts a low GL. Compared to an equal amount of carbohydrate from white bread, raisins had a significantly lower postprandial glucose and insulin response. This indicates that raisins can modulate the glycemic response (Fig. 1). A single-crossover study found little difference between the glycemic responses to 100-cal servings of grapes or raisins among subjects with type 2 diabetes. Insulin AUC value for raisins was lower than that for grapes (2970 ± 849 and 3960 ± 1370), but the difference was not significant .
Differences in blood glucose responses were found when subjects were given a nut and dried fruit snack (raisins and peanuts) or processed snacks (chocolate-coated candy bar or a cola drink with crisps) . Peak glucose concentrations tended to be higher after the processed snacks than after the peanuts raisin snacks and plasma insulin levels were significantly lower, despite having similar amounts of total carbohydrate, sugar, fat, and protein. Factors thought to contribute to raisins’ lower glycemic response were the food matrix, the presence of tartaric acid, and the type of sugar present. Because of their fat content, adding nuts to a dried fruit snack would be expected to lower the glycemic response. Pistachios consumed with a carbohydrate containing food (pasta, parboiled rice, mashed potatoes) reduced in a dose-dependent manner the total postprandial response by 20 – 30 % .
Eating fruit has been associated with reductions in body weight. The association between raisin intake (together with other dried fruits) and body weight was examined in a cross-sectional study (n = 13292 adults). Individuals consuming more than 20 g dried fruit per day had higher energy intakes than those who consumed less, but had a lower mean body weight, body mass index, and waist circumference. Moreover, after adjusting for potential confounders, prevalence of overweight/obesity and abdominal obesity was lower for those in the group consuming more dried fruit .
Intervention studies with raisins show that consumption may have a beneficial effect on blood lipids. In a study on hyperlipidemic subjects, a diet providing 126 g of raisins per day reduced total cholesterol and LDL cholesterol by 13 and 16 % respectively, but did not affect plasma triglyceride levels . After consuming Mediterranean-style diets that provided 84 g of raisins and mixed nuts and olive oil daily for 4 weeks, cholesterol and LDL cholesterol were 9 and 15 % lower, respectively, in hypercholesterolemic men [43, 44].
Anderson found that among mildly hyperglycemic and hypertensive subjects (n = 31), eating raisins three times per day over a 12-week period, significantly reduced post-meal glucose and HbA1C levels when compared with subjects (n = 15) eating popular commercial non-fruit snacks (e.g. crackers, cookies) of the same caloric content . Hypertension is a primary risk factor for cardiovascular disease. Raisin consumption was also associated with statistically significant reductions in both systolic and diastolic BP. No significant changes in body weight were observed within or between groups.
A 12-week randomized study (n = 57) evaluated the effect of routine intake of either raisins or processed snacks on glucose levels and other cardiovascular risk factors among patients with type 2 diabetes. In this study, those who consumed raisins had a significant 23 % reduction in postprandial glucose levels (p = 0.024) compared to those consuming processed snacks. Also, compared to snack consumption, those who consumed raisins had a 19 % reduction in fasting glucose and a non-significant reduction of 0.12 % in HbA1c. Compared to processed snacks, those who consumed raisins had a significant reduction in systolic BP, but not in diastolic BP. Body weight, BMI, waist circumference, fasting insulin, homeostatic model assessment of insulin resistance, total cholesterol, LDL, HDL, triglyceride, or non-HDL cholesterol levels did not differ with treatment  (Table 4). These results highlight the impact that the composition of snacks can have on blood sugar.
In another study, a group of patients with well-controlled type 2 diabetes were instructed to eat fewer fruits and vegetables than the recommended five servings per day and were given two servings of Corinthian raisins or snacks of similar energy density for 24 weeks. Consuming raisins significantly lowered diastolic BP and increased total antioxidant potential compared to levels at baseline. Raisins did not affect body weight, glycemic control, lipid profile, or C-reactive protein .
Fructose comprises approximately 50 % of the available carbohydrate content of raisins . When recommending increased consumption of fruit, especially dried fruit, concerns have been raised about the effects of fructose on cardiometabolic health. Several systematic reviews and meta-analyses have found that isocaloric exchange of fructose for other carbohydrates has no effect on several cardiometabolic risk factors. One meta-analysis found that isocaloric substitution of fructose had no effect on long-term glycemic control in individuals with diabetes . Isocaloric substitution of fructose for other carbohydrates does not increase postprandial triglycerides or other established lipid targets for CVD . The association of fructose consumption with hypertension and weight gain has also been examined and no relationship found . Fructose that provides excess energy has been associated with increased body weight. However, this may be due to the excess calories, rather than excess fructose, specifically .
Proposed World Health Organization (WHO) Guidelines on sugar consumption recommend limiting added sugar intake to less than 10 % of total energy intake per day and that reducing intake further, to less than 5 % of energy intake, would have additional health benefits . Similarly, the 2015 DGAs has recommended a goal for the general population of a maximum of 10 % of total calories from added sugar per day . The limits apply to all sugars (glucose, fructose, sucrose) added to foods by manufacturers and consumers. It also includes sugars present in honey, syrups, fruit juices, and fruit concentrates, but not the sugars naturally present in whole fruit, including traditional dried fruit.
Nuts and cardiometabolic health
Nut consumption has been associated with a reduced risk for cardiovascular disease and diabetes [12, 14, 52, 53]. While the evidence is stronger for cardiovascular disease protection, these conditions are related and are both believed to be inflammatory in nature. Prospective studies [54, 55] and clinical trials have found nut consumption to be associated with decreases in inflammatory markers [5, 13, 56].
Large prospective studies have found an association between nut consumption with a lower risk of fatal coronary heart disease (CHD) . The more frequent the intake, up to 5 or more times per week, the lower the risk. Lower total mortality has also been associated with frequency of nut consumption [12, 14, 57]. Despite a documented increase in caloric intake among nut consumers, a meta-analysis of randomized clinical trials found no association between nut consumption and increased body weight, BMI or weight circumference . The PREDIMED study, which evaluated the effects of a Mediterranean Diet, rich in nuts (30 g/day) or extra virgin oil (50 g/day), versus a lower fat diet, reported reduced cardiovascular events (by 30 % after 4.7 years) in individuals at very high risk of CVD who consumed the Mediterranean diets . In this study, the risk of stroke was also reduced in the two Mediterranean–diet groups . A systematic review of twenty prospective cohort studies involving 467,389 participants, comparing highest to lowest nut consumers found that nut consumption was associated with a 44 % lower risk of total CVD, a 27 % risk of death from any type of CVD, a 34 % lower risk of all CHD, a 30 % lower risk of CHD mortality and a 47 % lower risk of sudden cardiac death .
However, not all studies have been consistent in finding an association between nut consumption and a reduction in disease risk. Two recent meta-analyses of prospective studies found that while a higher consumption of nuts (one serving per day or more) was associated with reduced risk of coronary artery disease (CAD) and hypertension, no association was found between nut consumption and stroke or type 2 diabetes [61, 62]. A German cohort study of 26 285 participants also failed to find an association between nut consumption and the risk of stroke . However, a more recent meta-analysis of 9 prospective cohorts with 476,181 participants found a significant inverse association between nut consumption and stroke mortality among women . Similarly, a meta-analysis of 8 prospective cohort studies found that a high intake of nuts, but not legumes, was inversely associated with stroke risk . Another meta-analysis of prospective studies found that consumption of nuts (>2 servings a week) was inversely associated with hypertension risk, but not with risk of type 2 diabetes . The Multi-Ethnic Study of Atherosclerosis (MESA) and the Nurses’ Health Study evaluated the effect of nut consumption on several inflammatory markers, with mixed results. The MESA trial found an association between nut consumption and lower CRP, IL-6, and fibrinogen levels . The Prevención con Dieta Mediterránea (PREDIMED) study found lower ICAM1, but no differences in the other inflammatory markers were found . The Moli-sani prospective study of a Mediterranean population found a reduction of inflammatory markers (CRP, platelet count, and neutrophil to lymphocyte ratio) among nut consumers, but the impact on CVD was limited to a non-significant trend . The Nurses’ Health Study found no association between nut consumption and any of the inflammatory markers measured .
The majority of short-term clinical trials, conducted in otherwise healthy adults with type 2 diabetes or metabolic syndrome, are in agreement that an improvement in glucose and insulin metabolism occurs in the postprandial state with the consumption of 28–90 g of almond, pistachios or mixed nuts [41, 69–72].
The results from several long-term clinical trials conducted with different populations—some were obese, some had type 2 diabetes—and fed different types of nuts (almonds, walnuts, pistachios, almonds, and mixed nuts) are less consistent. Some found no effect of nut consumption on glucose and insulin metabolism [73–77]. Others found significant reductions in glucose, insulin, and HBA1c [78, 79] when two ounces of nuts replaced carbohydrate foods in the diet, suggesting health benefits . A systematic review and meta-analysis of 47 RCT with subjects diagnosed with dyslipidemia, metabolic syndrome, or type 2 diabetes mellitus, showed significant reductions in triglycerides and fasting blood glucose among those given the diets supplemented with tree nuts (~50 g/day), compared with control diet interventions . As with the majority of studies, nut consumption had no effect on waist circumference, or high-density lipoprotein cholesterol. BP was unaffected. A more recent systematic review and meta-analysis of 21 randomized controlled clinical trials to estimate the effect of nuts on BP found that total nut consumption lowered systolic BP in participants without type 2 diabetes. Pistachios appeared to have the strongest effect in reducing both systolic and diastolic BP .
The beneficial effects of pistachios on cardiometabolic risk factors have recently become the focus of research efforts. Pistachios are higher in β-carotene, lutein and γ-tocopherol, than other tree nuts, making them good sources of antioxidants, and they are higher in phytosterols, which are proven to reduce plasma total cholesterol and LDL-C levels. A clinical feeding trial was conducted in 54 middle-aged, overweight or obese subjects (average for the two groups, BMI 28.76–28.90) with pre-diabetes, given 57 g of pistachios daily or a control diet for 4 months, each with a 2-week washout period in between . Significant decreases in glucose, plasma insulin, HOMA-IR, HbA1c, fibrinogen, and platelet factor 4 and a significant increase in glucagon-like peptide-1 were observed as a result of the pistachio diet (Table 5). Waist circumference, BMI, and weight did not change. While no changes in the classic markers of cardiovascular disease, such as total cholesterol, LDL-C, and HDL-C, were observed, oxidized LDL-C was significantly lower when the diet was supplemented with pistachios.
There is limited evidence about the effect of nuts on modulating lipoprotein size and composition. A randomized, cross-over, controlled feeding study (a balanced order sequence of 4 weeks followed by a 2-week compliance break) was conducted to evaluate the cholesterol-lowering effects of diets containing either 1 or 2 servings of pistachios as part of an isoenergetic diet (10 and 20 % of energy, respectively) . Consuming 2 servings of pistachios per day significantly decreased small and dense LDL and lowered the TAG:HDL ratio. In addition, both pistachio diets raised levels of α-1 and α-2 HDL particles. More recently, a randomized cross-over, controlled, feeding study was conducted to investigate the effect of pistachio consumption (57 g/day) on lipoprotein subclasses in pre-diabetic individuals. There was a shift in lipoprotein size and particle profile to a less atherogenic pattern. This suggests that pistachios may play a beneficial role in CVD, other than an effect on the classic lipid factors of cardiovascular risk .
Taken together, these results suggest that regular consumption of pistachios, as part of a moderate-fat diet, could have important glucose- and insulin-lowering effects, promote a healthier metabolic profile, and reverse certain metabolic consequences of pre-diabetes.
Obesity is an importan risk factor for CVD and type 2 diabetes. There is a perception among consumers that including nuts in the diets on a regular basis will result in weight gain. However, the evidence base does not support this perspective. The results of a meta-analysis of 33 randomized clinical trials found no association between consumption of nuts and body weight (0.47 kg), BMI (0.40), or weight circumference . In fact, there was a non-significant decrease in all three—body weight (0.47 kg), BMI (0.40), and weight circumference (1.25 cm).
Nuts provide fiber, MUFA and PUFA and are low in SFA. Many are rich sources of tocopherols, phytosterols, and omega-3 fatty acids (alpha linolenic acid). These nutrients may improve inflammatory status, decrease total and LDL-cholesterol, reduce lipid peroxidation, and modulate endothelial function, resulting in beneficial effects on cardiovascular risk factors [52, 53, 84]. Nuts, particularly pistachios, have a high L-arginine content a precursor of endogenous vasodilator nitric oxide, which may contribute to vascular reactivity . Nuts are also high in polyphenol antioxidants, which may act by binding to lipoproteins, thus inhibiting the oxidative processes that lead to atherosclerosis. Finally, nuts are a good source of many micronutrients that play a role in in CVD risk, including low sodium, high magnesium, potassium and calcium . Individually or in combination, these compounds also have the potential to affect glucose metabolism. In diabetes, lymphocytes are hyperreactive, taking in large amounts of glucose. This increased glucose uptake by lymphocytes may lead to immune hyperactivity and inflammation . A significant decrease in cellular glucose transport (CGT) activity has been demonstrated with nut consumption, as well .
Several biological mechanisms could explain why, despite a relatively high calorie and fat content, consumption of nuts is not associated with weight gain. Nuts are rich in unsaturated fatty acids, which may have a greater thermogenic effect than saturated fats, resulting in less fat storage . Nuts are more satiating than many other foods, due to their energy density, fiber, and protein contents and consumption results in fewer calories consumed at subsequent eating occasions . In addition, not all of the fat in nuts is absorbed following consumption, resulting in an overestimation of their caloric contribution to the diet . This has been demonstrated in almonds  and pistachios .
Although several studies have found no significant changes in classic lipid profiles as a result of adding nuts to the diet, the antiatherogenic properties of nuts could be the result of alterations in various lipoprotein subclasses, including an increase in the size of LDL particles. A crossover study of 18 hyperlipidemic subjects fed walnuts (48 g) in addition to their habitual diets for 6 weeks resulted in no change in total cholesterol and apolipoprotein B concentrations . Although there was no change in these lipid concentrations, the distribution of lipoprotein subfractions was altered. The addition of walnuts decreased the amount of cholesterol in the small LDL fractions and concentrations of apolipoprotein A-1 increased, indicative of a decreased risk for CHD.
Dried fruits are very low in sodium and are a particularly significant source of potassium and fiber. On a per serving basis, traditional dried fruit can deliver over 9 % of the Daily Value of these nutrients, depending on the fruit. Both of these nutrients play an important role in reducing the risk of cardiovascular disease, hypertension, and stroke [90–92]. Dried fruits are also excellent sources of polyphenols and phenolic acids . These make up the largest group of plant bioactive compounds in the diet and appear to be responsible, at least in part, for the health benefits associated with the consumption of diets abundant in fruits and vegetables [94–96].
Increasing nuts and traditional dried fruit intake may displace intake of less healthy foods/snacks that are high in sodium or high in refined sugar, reducing glycemic load and possibly affecting cardiometablic risk factors. The spectrum of dietary antioxidants from nuts and dried fruits (tocopherols, carotenoids, polyphenols and phenolic acids) may lower overall oxidative stress by scavenging or neutralizing oxidant species and enhancing endogenous antioxidant defenses against metabolic impairment [3, 60]. Nuts and dried fruit are nutrient-rich foods, which provide micronutrients and bioactives that are individually associated with lower risk of CVD risk and metabolic disorders. The pairing of these foods thus would benefit many risk factors and physiological pathways.
Only a small percentage of the US population regularly consumes tree nuts or dried fruit, yet tree nuts, along with dried fruit, are among the foods associated with some of the largest shifts toward a higher HEI score. As shown in the NHANES data, consumers of tree nuts and dried fruit had HEI scores of about 60, an improvement over the average HEI of the U.S. diet, which is about 50, but there is still enormous room for improvement. Increasing the intake of dried fruits and tree nuts, would improve nutrient intakes and the quality of the American diet.
Consumption of both nuts and dried fruit has been associated with decreases in waist circumference and BMI. A limited number of clinical studies on raisins and cardiometabolic health suggest that they can lower the postprandial insulin response, modulate sugar absorption, and have a beneficial effect on BP. Additional longitudinal studies are needed to confirm associations of dried fruit intake on these parameters. A larger body of evidence has suggested that regular consumption of nuts, such as pistachios, as part of a moderate-fat diet, could have important glucose- and insulin-lowering effects, promote a healthier metabolic profile, and reverse certain metabolic consequences of pre-diabetes.
Nuts and dried fruit have a complementary set of nutrients. Both are shelf-stable, portable, and accessible and, in many instances, they are consumed together as snacks or prepared foods. Yet, no study has evaluated the nutritional or health impact of nuts and dried fruits consumed together. Emerging data support the potential of pairing tree nuts and dried fruit, such as pistachios and raisins, as a way to reduce cardiometabolic risk factors, improve glycemic control and decrease the risk of developing diabetes and/or cardiovascular disease.
