5. Avocados
Avocados help slow aging mainly by supporting skin health through their high content of healthy fats and antioxidants, especially vitamin E and vitamin C. These nutrients protect your skin from damage, boost collagen production, and keep it smooth and hydrated. The healthy fats in avocados also fight inflammation, which is linked to aging and many health problems.
How much to Eat: About ½ to 1 avocado a day is enough to get the benefits without overdoing calories.
