Sweet potatoes - anti-aging food

The sweet potato has been ranked continuously as the most nutritious vegetable source around.

They're loaded with four times the recommended daily allowance of beta carotene, which is critical for healthy vision, bone growth, tooth development and good skin and hair. And for Atkins dieters who are cutting down on sugars and carbs, sweet potatoes are on the safe list as a great substitute for other starches such as rice, potatoes and corn.

So instead of vaguely resolving to eat healthy, take some simple, but specific steps such as learning to recognize good fat over bad fat and good carbs over bad carbs. Pay attention to the calories but also know which foods stand out for their high nutritional content.
