Micronutrients & recovery
Consumption of sweet potatoes (Ipomoea batatas) as a staple carbohydrate provides significant antioxidant benefits, including high levels of beta-carotene, vitamin C, and specific polyphenols, which may reduce oxidative stress and inflammation.
Include sweet potatoes, especially the Satsuma Imo variety, in your diet. They are low-GI, rich in antioxidants like beta-carotene and anthocyanins, and provide essential vitamins. They are a nutrient-dense alternative to refined grains.
