Moderate consumption of about 5 walnuts daily is recommended, as it can help reduce bad cholesterol and prevent cardiovascular problems. Additionally, their richness in healthy fats, lecithin, and minerals benefits the brain, reducing memory loss and improving mood, including depression and insomnia. Walnuts are also rich in calcium and other minerals, helping to keep bones healthy and prevent osteoporosis, especially in older adults and women during menopause. Their richness in vitamins A, B1, B6, C, and E makes them allies in enhancing skin and hair health. Despite their high caloric content, their satiating effect helps control appetite and prevent obesity. It is suggested to store them in their shell to maintain freshness longer and enjoy them in various recipes or as a snack at any time of day.
