WHAT TO EAT

All bodies need vitamins to promote growth and health. Some vitamins are needed because the body cannot make them at all or makes them in insufficient amounts so food intake must supply them. To get your Vitamin A, eat dark green and yellow fruits and vegetables, eggs, low-fat dairy products, and liver. Vitamin D is taken into the body by eating egg yolks, fatty fish (like tuna and salmon, sardines and herring), and drinking fortified milk. Getting your daily Vitamin C can be accomplished by eating citrus fruits, tomatoes, melons, berries, red peppers, green peppers, and broccoli. Proper calcium in your diet can be provided by including yogurt or other dairy products, cheese, tofu, vegetables such as broccoli and peas, beans, enriched grains as well as seeds and nuts.

WHAT NOT TO EAT

Stay away from foods that are high in calories, salt, sugar, and the wrong kinds of fat such as fast foods or processed and pre-packaged foods. Most meals that fall into this category are deficient in essential nutrients and can pack on the pounds quickly. Salt and sugar interfere with the body’s metabolism by altering insulin processes and blood pressure among other destructive behaviors. Tooth decay and gum disease should be watched carefully if you fill your diet with fast foods or processed foods. The sugars included in these foods can cause tooth decay to increase rapidly.
