For optimal nutrition, choose foods that are in their natural state. Unprocessed, fresh foods are wonderful opportunities to make sure you get the nutritional requirements you need, while avoiding chemicals and fats.
To keep your diet healthy, you should try to consume many fruits and vegetables each day. The USDA recommended daily allowance of fruits and veggies combined is 9-13 servings a day. That sounds like a lot, but it's really not difficult to fit them in. Have a glass of real orange juice with your breakfast or put tomato pasta sauce on your spaghetti.
Eating fresh fruits and veggies daily is good nutrition advice. Nine to thirteen servings of fruits and vegetables a day is the USDA recommended amount. That sounds excessive, but it can be done with some creative thinking. A fresh glass of orange juice or a tomato-based sauce on pasta can count as servings.
