In the average North American diet, the primary source for B12 is animals. To have an adequate intake of B12, vegans should reguarly consume vitamin B12 supplements or foods, which contain vitamin B12, such as soy products or milk. For calcium, vegans can rely on orange juice or soy milk, as they are fortified with calcium. The average individual eats too much fat, a factor that's linked to a variety of health problems, including cancer. Diets that are high in fat are associated with breast and colon cancer, with some studies linking high fat to prostate cancer as well. A majority of people can bring their fat intakes down to a healthy range by making a few adjustments in the way they shop, cook, and prepare the foods they eat. A single apricot contains 17 calories, 0 fat, and one gram of fiber. You can eat them dried or soft. Mango A medium sized mango packs 57 MG of vitamin C, which is nearly your entire daily dose. This antioxidant will help prevent arthritis and also boost your immune system. Cantaloupe Cantaloupes contain 117 GG of vitamin C, which is almost twice the recommended dose. What this means, is that the drinks contain a lot of energy that your body may not need, and it doesn't contain any vitamins or minerals. If you plan to drink sugary drinks, don't go overboard - limit yourself to 1 a day. 4. Avoid thinking about diets There are no good food nor any bad foods. All food can be a part of a healthy diet, when eaten in moderation. Even though the holidays are in, don't forget about the exercise. Keeping weight off during the holiday season is burning off the extra calories. You should plan a walk after meals, park farther from stores when you shop, and take a few walks around the mall before you begin shopping. During holiday parties and at family dinners, feel free to sample foods although you shouldn't splurge. Without listening to them, you are forcing your body to run without any fuel. Before you exercise or do any physical activity, always eat a light snack such as an apple. 2. Relying on energy bars and drinks. Although they are fine every once in a while, they don't deliver the antioxidants you need to prevent cancer.
