Nuts and seeds are essential components of a Paleo meal plan that contribute significantly to the antioxidant content. These nutrient-dense foods are rich in vitamins, minerals, healthy fats, and antioxidants that provide numerous health benefits.
Antioxidants in Nuts and Seeds
Antioxidants are compounds that help protect the body from oxidative stress and damage caused by free radicals. Nuts and seeds are packed with various antioxidants, including vitamin E, vitamin C, selenium, and polyphenols.
- Vitamin E: Nuts such as almonds, hazelnuts, and sunflower seeds are excellent sources of vitamin E, a powerful antioxidant that helps protect cells from damage.
- Vitamin C: Seeds like pumpkin seeds and sunflower seeds are rich in vitamin C, which boosts the immune system and helps neutralize free radicals.
- Selenium: Brazil nuts are one of the best sources of selenium, a mineral that acts as an antioxidant and plays a crucial role in thyroid function.
- Polyphenols: Flaxseeds, chia seeds, and walnuts are high in polyphenols, plant compounds with antioxidant properties that help reduce inflammation and prevent chronic diseases.
