Walnuts are one of the world’s oldest foods and have been cultivated for at least 2,000 years. These nutritious nuts have been linked to love and fertility throughout history and their reputation as an aphrodisiac dates back to ancient Greece and Rome. Walnuts are one of the best plant sources of protein. They are rich in fiber, B Vitamins, magnesium and antioxidants such as Vitamin E. Walnuts are also high in fat – mostly monounsaturated and polyunsaturated fats (omega 3 fatty acids- the good fats) that have been shown to lower LDL cholesterol. Walnuts, in particular, have significantly higher amounts of omega 3 fatty acids as compared to other nuts. For a complete list of nutrients in walnuts please read more here…
The health benefits of walnuts are plenty:
Walnuts in particular have a unique profile: they are rich in polyunsaturated fatty acids, which may improve blood lipids and other cardiovascular disease risk factors. FDA endorsed the health benefits of walnuts by approving the following health claim in March 2004. FDA states “supportive but not conclusive research shows that eating 1.5 oz of walnuts per day, as part of a low saturated fat and low cholesterol diet, and not resulting in increased caloric intake may reduce the risk of coronary heart disease”. Also there is other scientific evidence for a beneficial health relationship between walnuts and coronary heart disease.
Plant-based omega-3 polyunsaturated fatty acids (PUFA) may have a protective effect on bone health, according to a team of Penn State researchers who carried out the first controlled diet study of these fatty acids contained in such foods as flaxseed and walnuts.
A Yale study published in Diabetes Care finds walnuts improve blood flow in adults with type 2 diabetes. The researchers concluded that a walnut-enriched diet may improve endothelium-dependent vasodilatation in individuals with type 2 diabetes, thus reducing overall cardiac risk. It should be noted that not all of the individuals exhibited this improvement.
Walnut consumption may provide the body with essential omega-3 fatty acids, antioxidants and phytosterols that reduce the risk of breast cancer, according to a study presented at the American Association for Cancer Research 100th Annual Meeting 2009.
Elaine Hardman, Ph.D., associate professor of medicine at Marshall University School of Medicine, said that “Walnuts are better than cookies, French fries or potato chips when you need a snack, we know that a healthy diet overall prevents all manner of chronic diseases.”
The significant decrease in the α-T: γ-T ratio and a trend towards an increase in the ratio of free PSA: total PSA following a study suggest that walnuts may improve biomarkers of prostate and vascular status. Also, Walnut consumption slows the growth of prostate cancer in mice and has beneficial effects on multiple genes related to the control of tumor growth and metabolism, researchers at UC Davis and the U.S. Department of Agriculture Western Regional Research Center in Albany, Calif. have found.
Besides exercising regularly, adequate omega 3 fats are crucial in testosterone production. Omega 3 fats are found in walnuts, fish, and flaxseed. Walnuts’ reputation as an aphrodisiac dates back to ancient Greece and Rome.
