Eating peanuts has many health benefits, but some people should avoid them, especially boiled peanuts.
Peanuts are rich in healthy fats, protein, vitamins, minerals, and antioxidants. They may help protect the heart, reduce cholesterol, improve metabolism, and increase lifespan. Eating peanuts can also promote fullness, help control appetite, and stabilize blood sugar. Studies show they may lower the risk of rectal cancer and reduce the chance of gallstones.

However, peanuts are not suitable for everyone. People with peanut allergies must avoid them completely, as even small amounts can trigger dangerous reactions. Those with gout, high uric acid, or weak digestion should limit intake because peanuts may worsen symptoms. Eating too many boiled peanuts can also cause weight gain or stomach discomfort.
