Simply put, peanuts are delicious! And here are 13 awesome health benefits of peanuts.

1. Aids Weight Loss

In a balanced diet, peanuts aid weight loss. They’re full of unsaturated fats, protein, and fiber – all of which increase satiety. This means that you’ll stay full longer without binge eating later on. The result is reduced energy intake and, therefore, less weight gain.1 Boiled peanuts can be more helpful for weight loss than roasted or raw ones as the former contain lesser calories.


2. Lowers Cholesterol

Have high cholesterol? Eat peanuts and use peanut oil! Their rich levels of unsaturated fats reduce your total and LDL (“bad”) cholesterol.2 As a consequence, your risk of heart disease, stroke, and other cardiovascular problems take a nosedive.3 Any form of peanuts can help you here as they contain no cholesterol whatsoever.

3. Reduces The Risk Of Diabetes

Diabetes and heart disease go hand in hand. After all, diabetics often have high cholesterol, which places them at a great risk of heart disease and other complications. Because peanuts are beneficial to the heart, they can be used to decrease the severity of diabetes.4


Peanuts also have manganese, a trace mineral that regulates blood sugar. It offers protection from LDL cholesterol.5 Peanuts can be eaten in any form, raw or cooked, and still be a healthy choice for diabetics.

4. Lowers Blood Pressure

If you’re dealing with hypertension, peanuts will have favorable side effects because the omega-3 fatty acids in them will lower your blood pressure. And without hypertension, your risk of heart disease, stroke, and other chronic diseases will decrease.6


Salted peanuts will add to your sodium intake and worsen your blood pressure. So although you can have boiled or roasted peanuts, do not salt them.

5. Results In Healthier Skin

Unsaturated fatty acids have amazing anti-inflammatory properties. So if your skin’s stressed out, it’ll love peanuts! These fats protect the skin from sun damage, reducing the risk of wrinkles and sun spots. They even protect collagen-making cells called fibroblasts. With more collagen, fine lines will be less noticeable.


Other benefits of peanuts for the skin come from their power to heal wounds. This includes everything from minor cuts to acne. And lowered inflammation encourages the skin to recover faster.7 Peanuts are also a great source of vitamin E, which boosts the anti-inflammatory and antioxidant benefits for the skin. Peanuts in any form will provide you all of these benefits.

6. Prevents Cancer

Peanuts are a good complimentary food in the treatment of various types of cancer.

  • Peanuts contain compounds called phytosterols that exhibit anticancer properties, especially against breast, colon, and prostrate cancer.8
  • Eating peanuts or peanut products might even reduce the growth of cancerous cells in women with colorectal cancer.9
  • They might also ward off skin cancer. Both unsaturated fats and vitamin E stop the damage and inflammation due to UV ray exposure. Your skin’s immune system also flourishes, resulting in stronger protection.10 11

7. Treats Arthritis

Arthritis is a chronic inflammatory condition that impacts more than 50 million American adults.12 But thanks to the anti-inflammatory advantages of peanuts, joint pain can be decreased. The niacin in peanuts also improves arthritic symptoms while increasing joint mobility. Peanuts are a good natural alternative to nonsteroidal anti-inflammatory drugs (NSAIDs).13 Cook them, roast them, or eat them raw, just as you like.

8. Represses Alzheimer’s

They contain a compound called resveratrol that has been proven to reduce cell death, protect the DNA, and prevent neurological damage in Alzheimer’s patients.14 Boiling or roasting peanuts is preferable as the process might increase the levels of this compound.15


9. Protects The Heart
