Nuts

  • Nuts ( nuts, almonds, cashew, peanut, pecan, pine nut, pistachio nut, macadamia nut, hazelnut, walnut) are a good source of macronutrients and micronutrients. 
  • Nuts are rich in unsaturated fatty acids, fiber, high-quality vegetable protein, and minerals (eg, magnesium and potassium). 
  • Nuts also have high contents of bioactive compounds, such as polyphenols, tocopherols, phytosterols, and phenolics. 
  • Walnuts are especially rich in polyunsaturated acids, including α-linolenic acid (omega 3). 
  • Previous clinical trials and epidemiologic studies have shown that nuts have beneficial effects on various mediators of chronic diseases, including lipid concentrations (eg cholesterol), inflammation, insulin resistance (diabetes), and blood pressure (BP). 
  • A review concluded that the consumption of nuts more than 5 times per week was associated with a reduced incidence of coronary heart disease (IHD). 
  • In the past several years, additional studies have been published on cardiovascular diseases, diabetes, and all-cause mortality.
  • A recent  meta-analysis indicates that nut intake is inversely associated with IHD, overall cardiovascular diseases, and all-cause mortality but not significantly associated with diabetes and stroke.
