The Recommended Daily Portion
For most healthy adults, consuming about one to two ounces (28 to 56 grams) of peanuts daily is considered beneficial. This amount is roughly a small handful and helps you gain health benefits without excessive calorie intake, as peanuts are calorie-dense due to their fat content.
- One ounce (28g): Contains around 166-180 calories, 7-8 grams of protein, and 2-2.4 grams of fiber.
- Two ounces (56g): Provides double the nutrients and calories.
Mind Your Peanut Butter
When eating peanut butter, a typical portion is two tablespoons. It's best to select natural, unsweetened, and unsalted options, as many commercial brands add sugar, salt, and unhealthy fats. Look for brands with minimal ingredients like 'peanuts and salt' or just 'peanuts'.
Nutritional Powerhouse: What's in a Handful?
Peanuts are rich in various nutrients:
- Protein: Higher in protein per ounce than many tree nuts.
- Healthy Fats: Contain monounsaturated and polyunsaturated fats beneficial for heart health and lowering 'bad' LDL cholesterol.
- Fiber: Aids digestion, increases fullness, and helps regulate blood sugar.
- Vitamins and Minerals: Provide B vitamins, vitamin E, magnesium, phosphorus, and manganese.
- Antioxidants: Include resveratrol, which helps fight oxidative stress and inflammation.
The Health Benefits of Daily Peanut Consumption
Moderate daily peanut intake offers several health advantages.
Supports Heart Health
Regular consumption is linked to a lower risk of coronary heart disease. The fats, fiber, magnesium, and antioxidants in peanuts improve cholesterol levels, blood pressure, and reduce inflammation.
Aids in Weight Management
Despite being calorie-dense, peanuts can help with weight management. Their high protein, fiber, and healthy fat content promote satiety, making you feel full longer and potentially reducing overall calorie intake.
Helps Manage Blood Sugar
Peanuts have a low glycemic index, resulting in a gradual release of glucose, which helps manage blood sugar and may lower the risk of type 2 diabetes.
The Risks and Downsides of Overindulging
Eating too many peanuts can lead to negative effects.
Weight Gain
Excessive consumption can cause weight gain due to high caloric density if not balanced with diet and exercise. A handful is a good guide to prevent overconsumption.
Digestive Issues
The high fiber content can cause discomfort like bloating or gas for some, especially those not used to a high-fiber diet.
Aflatoxin Contamination
Peanuts can be contaminated with aflatoxin from Aspergillus mold, linked to liver cancer with prolonged exposure. Purchasing from reputable brands with strict food safety measures reduces this risk. Inspect peanuts for signs of mold or discoloration.

How to Choose the Healthiest Peanut Products
Make smart choices to maximize health benefits:
- Opt for Unprocessed Versions: Choose raw, dry-roasted, or boiled to avoid added oils, sugars, or preservatives.
- Check the Ingredients: Peanut butter should ideally contain only peanuts and maybe salt. Avoid added sugars, hydrogenated oils, and palm oil.
- Go Unsalted: Excessive sodium increases blood pressure risk. Look for 'unsalted' or 'lightly salted'.
- Inspect for Quality: Check for mold or discoloration, indicating possible aflatoxin contamination. Buy from trusted brands.
