Recent research shows that specific chemicals our foods today such such as sulforaphane, a phytochemical in broccoli - work with your genes to ratchet up your body's natural defense systems, helping to inactivate toxins and free radicals before they can do the damage that leads to cancer, cardiovascular disease, and even premature aging.

And the hope for the future is to be able to tell someone what diseases or maladies they are might be genetically predispositioned to early on, so their diets can be focused accordingly. We'll know which ones to add, which ones to avoid, and be able to take a proactive role in preventing or deterring a genetic disease. In the meantime, many foods have been determined to pack a punch to the aging process.

Lycopene, the pigment that makes tomatoes red, also appears to reduce risk for cardiovascular disease, some cancers, and macular degeneration. It's also been associated in greater self-sufficiency in elderly adults. While fresh tomatoes have a good hit of lycopene, the most absorbable forms are found in cooked tomato products, such as spaghetti sauce and soup and prepared salsas. Pink grapefruit, guava, red bell peppers, and watermelon are also rich in lycopene.

Eating at least two cups of orange fruits like sweet potatoes, squash and carrots boosts intake of beta-carotene, which converts to vitamin A, essential for healthy skin and eyes, and which may also reduce the risk of some cancers, cardiovascular disease, and osteoporosis. Lutein and lycopene, also found in orange produce, also help reduce the risk of macular degeneration and may protect skin from sun damage and even reduce wrinkling as well. Mangos and cantaloupes are also beta-carotene endowed.

And if you don't do anything else to change your diet, eat your dark leafy greens. They have been showed to significantly reduce your risk for heart disease and may also save your eyesight. Dietary guidelines advise at least three cups of greens a week. Frozen or bagged is as good as fresh.

Don't forget the mental aging process either. The heart-healthy omega 3 fatty acids have also recently been shown to keep your brain sharp. A recent study found that a higher intake of fatty fish significantly reduced mental decline. If fresh fish isn't an option, go for canned tuna, salmon, and sardines.

Nutrition to Fight Flatulence

There are many causes for flatulence, such as overeating, eating too quickly, excessive consumption of refined carbohydrates or artificial sweeteners, food allergies and intolerance, a deficiency of vitamin B, excessive consumption of alcohol, emotional stress and parasites. One of the most common causes can be lactose, found in dairy products such as milk and cheese. Many other healthy foods can also cause gas, such as cabbage, beans, broccoli, Brussels sprouts, onions, cauliflower, whole wheat flour, radishes, bananas and apricots. Luckily, with some adjustments in our food choices and eating habits, the chances of this embarrassing malady can be greatly lessened or eliminated.

Do not overeat, and chew food slowly. Try to identify if it is a certain food causing the problem and eliminate it from your diet. Try chewing a sprig of parsley after meals. Try lemon juice or apple cider vinegar in water with your meal. You might also want to try sipping your drinks slowly through a straw in an effort to minimize the amount of air you take in during drinking.

Vitamin B complex, especially B3 (niacin) rich foods like light-meat chicken, tuna, salmon, turkey, enriched flour, peanuts, and fortified cereals can be helpful as they aid in the digestive process and in converting food to energy.

Yogurts that have acidophilus and peppermint oil in water sipped with the meal can also help with the digestive process. If the problem persists, you may want to try and eat proteins and carbohydrates in different meals.

In addition, peppermint and fennel-based teas are useful for occasional indigestion, particularly when there is flatulence and a sensation of fullness. Ginger has been shown to promote the flow of digestive juices, a normal process that supports the digestive system.
