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.
What Are the Healthiest Nuts?
While all nuts are generally healthy, some offer more specific benefits than others. Some of the most nutritious nuts include:
- Almonds: They are particularly rich in vitamin E.
- Pistachios: These small, green nuts provide a variety of nutrients, such as vitamin B6 and antioxidants. They are also slightly lower in calories compared to other nuts.
- Walnuts: They are known for their high levels of copper, manganese, and omega-3 fatty acids.
- Cashews: Native to South America, they provide vitamin K, magnesium, and manganese.
- Pecans: Native to North America, these nuts are a good source of zinc and manganese.
- Macadamia nuts: High in healthy fats and low in carbs, these nuts also provide vitamin B1, copper, and manganese.
- Brazil nuts: These large nuts come from the Amazon rainforest and are particularly high in selenium, a mineral needed for thyroid health.
- Hazelnuts: They are a good source of vitamin E, manganese, and antioxidants.
- Peanuts: Although technically legumes, they have a nutritional profile similar to nuts. Peanuts provide folate, which is especially important for pregnant people.
Nuts Are a Great Source of Many Nutrients
Nuts contain all three primary macronutrients: carbohydrates, fats, and protein. They are also a good source of micronutrients (vitamins and minerals) your body needs in small amounts.

Key Health Benefits of Nuts
1. Reducing the Risk of Disease
The antioxidants found in nuts may help combat oxidative stress that leads to various diseases. Research suggests a correlation between regular nut consumption and a reduced risk of cancers such as colorectal and endometrial cancers. Additionally, nut eaters have a 19% lower risk of premature death from all causes.
2. Aiding Weight Management
Despite their high fat content, nuts can assist with weight loss. A study involving over 373,000 participants revealed that those who incorporated nuts into their diet experienced less weight gain. The fiber content in nuts may lead to increased satiety, helping to curb cravings and maintain a healthy weight.
3. Lowering Cholesterol and Triglycerides
Nuts are known to positively affect cholesterol levels, primarily due to their monounsaturated and polyunsaturated fats. Studies have shown that various nuts, including almonds, walnuts, and pistachios, can help reduce both total and LDL cholesterol levels and triglycerides.
