What Happens to Your Body When You Eat Nuts Regularly (2025)

Nuts are loaded with nutrients that can improve your overall health. They contain protein, fiber, vitamins, minerals, and antioxidants. They are also rich in unsaturated fats, which are considered "good" fats.

Consuming nuts as part of a well-balanced diet can offer health benefits, such as promoting weight loss, lowering your risk for heart disease, improving digestion, supporting your immune system, and more.

1. Reduces Disease Risk

Nuts contain antioxidants, which may fight off cell damage that triggers certain diseases. Some research suggests that eating peanuts or tree nuts may help reduce the risk of colorectal, endometrial, and pancreatic cancer.People who consumed more nuts had a 19% lower risk of dying prematurely from any cause.

2. May Aid Weight Loss

Though they are high in fat, nuts may promote weight loss. One study analyzed the lifestyle habits of more than 373,000 participants. Researchers found that people who included nuts in their diets gained less weight during the study period. The nut eaters also had a 5% lower risk of becoming overweight or obese. Some experts believe that because nuts contain a lot of fiber, they may keep you full longer, which can lessen cravings.

3. May Lower Cholesterol and Triglycerides

Nuts are known to lower cholesterol and triglyceride levels, which may protect your heart. The cholesterol-lowering effects are likely due to the high content of the nut's monounsaturated and polyunsaturated fatty acids. Research has found most nuts, including almonds, walnuts, cashews, peanuts, and pistachios, may help decrease total cholesterol, LDL cholesterol, and triglyceride levels.

4. Helps Manage Type 2 Diabetes and Metabolic Syndrome

Research suggests that nuts may be a good option for managing type 2 diabetes and metabolic syndrome. They are naturally low in carbs, so they won’t significantly raise blood sugar levels. Experts consider nuts as a diabetes superfood.

5. May Reduce Inflammation

Nuts contain compounds that may reduce inflammation linked to various diseases, such as cancer, heart disease, and arthritis. In a study, people who followed the Mediterranean diet and consumed nuts experienced decreased inflammatory markers of C-reactive protein (CRP) and interleukin 6 (IL-6).

6. Helps Balance Gut Bacteria

Some studies suggest that nuts may help promote gut health. The fiber in nuts functions as a prebiotic, which helps balance gut bacteria. Additionally, nuts contain polyphenols, which could boost gut health.

7. May Reduce Risk of Heart Attack and Stroke

One review found that eating more nuts was linked to a 24% lower risk of heart disease and an 18% lower risk of stroke mortality.Researchers believe consuming nuts has a positive impact on preventing cardiovascular diseases.
