1. Key Health Benefits of Nuts

1) Promoting Heart Health

Nuts are rich in unsaturated fatty acids, which help lower bad cholesterol (LDL) and increase good cholesterol (HDL), contributing to the prevention of cardiovascular diseases. In particular, walnuts, almonds, and pecans are known to be beneficial for heart health.

2) Enhancing Brain Function

Walnuts, which contain high levels of omega-3 fatty acids, help improve memory and concentration. Additionally, almonds are rich in vitamin E, which protects brain cells and helps prevent dementia.

3) Boosting Immunity

Nuts are packed with antioxidants such as vitamin E, selenium, and polyphenols, which help prevent cell damage and strengthen the immune system. Especially, Brazil nuts are rich in selenium, which acts as a powerful antioxidant.

4) Supporting Weight Management

Nuts contain healthy fats and proteins, helping maintain satiety for an extended period. However, as they are calorie-dense, it is best to consume about one handful (approximately 30g) per day.

5) Improving Skin Health and Preventing Aging

Nuts contain vitamin E and polyphenols, which enhance skin health and slow down aging. Especially, almonds and cashews help maintain skin elasticity.
