As more and more studies emerge regarding the effect of certain foods on our health and longevity, it tends to get more difficult to stay current on information. It's as if every time we turn around, a nutrition fact that we once took for granted has suddenly been erased. And in the quest for optimum health, it's difficult to know where to turn - and how to separate nutrition fact from fiction.

Luckily, when it comes to eating for health, there are a few guiding principles that remain nutrition fact. First and foremost, you can never go wrong with the eating of whole, natural foods. Experts agree that a consistent diet filled with fresh fruits green leafy vegetables, whole grains, and lean protein helps keep weight, blood pressure, and cholesterol under control and optimizes overall health.

Another nutrition fact that hasn't changed - and isn't likely to do so - is to minimize, and ideally avoid altogether, foods that are processed, fried, or high in saturated fats. Limit sweets and foods that are highly salted. If you focus your diet on natural, whole foods you are receiving all the nutrients that the food has to offer without the masking of preservatives or other additives.

An equally consistent nutrition fact is the importance of water in an overall healthy diet. Experts recommend the consumption of at least eight glasses of water each day to flush the kidneys and hydrate the body. Water will help keep metabolism at a steady pace and even acts as an appetite suppressant.

Now and again, we will stumble on a nutrition fact that has settled in the gray area of research. For instance, we were once told to avoid eggs at all costs as egg yolks are high in cholesterol and fat. But now, some diet plans make use of eggs and other proteins as meal staples, telling us to instead stay away from carbohydrates. Years ago, carbohydrates such as bread, potatoes, and rice were primary foods in an American diet. Now, carbohydrates have been demonized as a food choice.

In the face of all the information, it can be overwhelming when it comes to making good food choices. Ideally, balance is the key to success. It may be wise to work with a nutritionist who can best tailor a meal plan to fit your lifestyle and body type.

Ultimately, the nutrition fact that makes the most sense is everything in moderation. Choose predominately natural foods that pack vitamins and minerals into every serving; drink plenty of water; and sensibly indulge in foods you love.
