Nuts are a highly versatile food with a ton of health benefits. From heart health to weight management, nuts carry a lot of nutritional power in a tiny package.
Heart Health and Disease Prevention
Nuts are rich in antioxidants, which protect your cells from free radicals and help to prevent heart disease, cancer, and other aging-related diseases. 1 2 3 Free radicals are atoms or molecules made up of unpaired electrons that seek out electrons in the body to pair with. In doing so, free radicals damage cells, DNA, and proteins, which can lead to disease. 4 All nuts fight free radicals and prevent damage to cells, but walnuts are particularly effective.5
In addition to fighting free radicals in the body, nuts also contribute to heart health by lowering cholesterol. 6 Studies have shown that nuts lower bad (LDL) cholesterol and triglycerides while promoting good (HDL) cholesterol. 7 8 9
Weight Loss
All nuts have a relatively high fiber content, and because of this are effective in promoting weight loss. 10 This is because the high fiber content in nuts reduces the amount of calories that your body absorbs and also promotes the production of short-chain fatty acids (SCFAs), resulting in better gut health and less weight gain. 11 12 The fiber content of almonds, pistachios, pecans, and hazelnuts is especially high, so try adding these nuts to your diet more regularly if you are trying to lose weight. Nuts are calorie dense, however, so be sure to watch portion size when consuming them.
Nuts can be enjoyed raw on their own as a snack or added to a number of sweet and savory recipes. Here is a simple recipe that includes walnuts, nut butter, and is loaded with other nutritious ingredients.
