Adding nuts to your diet can boost your health!
Nuts are a composite of a seed and dry fruit surrounded by a hard outer shell. They are a nutrient dense food rich in heart healthy fats, vegetable protein, soluble fiber, vitamins, minerals, tocopherols, phytosterols and phenolic compounds.
Nut Nutrients (In A Nutshell)
- Monounsaturated fatty acids (MUFA)
- Omega-3 essential fatty acids (ALA)
- Polyphenolic flavonoid antioxidants such as carotenes, resveratrol, lutein and cryptoxanthin
- Vitamins, including B complex and E
- Minerals, including manganese, potassium, calcium, iron, magnesium, zinc, fluoride and selenium
- Fiber (about 2.3 g/ ¼ cup)
- Protein (about 6.7 g/ ¼ cup)
Due to their unique composition of macro, micro and phyto nutrients, nuts have been shown to have a number of health promoting benefits.
An Ounce of Nuts Is Equal To A Pound of Prevention (And Cure)
Numerous studies have shown a positive correlation between nut consumption and a reduced incidence of coronary heart disease, gallstones, diabetes, hypertension, cancer, metabolic syndrome and oxidative stress. In addition, consuming nuts has a cholesterol-lowering effect. Regular nut consumption (approx. ¼ cup) is unlikely to cause weight gain or contribute to obesity. In fact, nuts have been shown to lower body weight and fat mass. (Blomhoff, R., et al. 2006) (Rajaram, S., & Sabaté, J. 2006) (Ros, E. 2010) (Sabaté, J., & Ang, Y. 2009)
When it comes to nutrient density, almonds are the highest in protein, fiber, calcium, vitamin E (alpha-tocopherol), riboflavin and niacin. Among tree nuts, they are the best source of six of the 13 nutrients for which there are DVs/DRVs and among the lowest in calories.
Mixed, raw and unsalted nuts provide the best variety of nutrients and antioxidants.
Dose: Let Food Be Thy Medicine
Patients with metabolic syndrome (elevated serum lipids, insulin resistance, and inflammatory biomarkers) show improvements after daily intake of 30 g of mixed nuts.
(Casas-Agustench, P., Let al. 2011)
Raw vs Oil Roasted With Salt, etc.
Oil roasted nuts with added salt have a higher calorie, fat (usually omega 6 and/or trans fats) and sodium content, which could lead to an increased risk of obesity, high cholesterol, heart disease, hypertension and inflammation. Many trail mixes contain added oils, salt, sugar and gluten. Read the label and try to avoid these.
Nut Allergies
The most common nut allergies include: peanuts (53%), pecan (26%), almond (25%), walnut (22%), cashew (16%), pistachio and Brazil nut (10%), hazelnut and macadamia nut (9%), and pine nut (6%). Overall, the estimated prevalence of peanut and/or tree nut allergies is about 1.4% While reactions can vary, those with known nut allergies should avoid nut consumption.
