The health benefits of walnuts are numerous and have been well-documented by the American Food and Drug Administration (FDA). They help reduce heart disease by providing healthy doses of “good” fats like omega-3 fatty acids and they been shown to lower bad cholesterol. Walnuts have also be shown to lower C-Reactive Protein, which is a strong indicator of heart disease. Combined with their heart health benefits, walnuts are also high in vitamins like B-12 and Vitamin E as well as in magnesium, protein and antioxidants, which have been shown to help prevent a wide range of health problems, including cancer.

The FDA recommends eating 1.5 ounces(42.5) grams of walnuts or similarly healthy nuts per day without adding to daily caloric intake. Most nuts, including walnuts, are high in calories and should be eaten in moderation despite their many health benefits. They should also be consumed in place of other, less nutritious, forms of protein such as cheese. Since protein is more filling than most fats and carbohydrates, eating the nuts can also be part of a weight loss plain because the stomach will stay full longer.
