I wish I could eat more healthy. Probably this list should help. The importance of eating fruits and vegetables cannot be overemphasized. If you need proof, take a look at Asian countries who rely on such natural foods for their diet.
Some of the foods that you shouldn't scrimp on are:
Apples: Apples are beneficial on so many different levels. They pack more Vitamin C than an orange and they are full of antioxidants that will help your body stay healthy.
Carrots: They are essential for eye health and there are a variety of different ways to add them to your diet. Cooking carrots does tend to lessen their benefits, so try to eat them raw when possible. Beta carotene can even help ward off cancer, especially skin cancer.
Tomatoes: Tomatoes are extremely rich in lutein, an incredible nutrient that can keep your eyes healthy. They also contain lycopene, which is an antioxidant.
