Both fats and carbohydrates play an important role in nutrition, and both are important to a healthy diet. It would be impossible and unwise to eliminate all fat from the diet, since fat is important for the production of energy, and for carrying valuable fat soluble vitamins like vitamin D, vitamin E and vitamin K, throughout the body. In addition, fat plays a vital role in regulating various bodily functions. Even though some fat is essential to a healthy body, too much fat can be harmful.

There are such things as good fat and not too good fat because not all fats are created equal, and some fats are more harmful than others. Saturated fats and Trans fats are generally understood to be more harmful in the diet than polyunsaturated and monounsaturated fats. These lighter fats, like canola oil and olive oil, should form the basis of cooking healthier diet. Keeping saturated fats and Trans fats to a minimum is important to a healthy diet. Trans fats, which are solid at room temperature, are most often found in highly processed foods like cookies, cakes and other baked goods. In addition, trans fats are often found in fried foods and in salty snacks like potato chips. While these foods are fine in moderation, it is best to avoid large quantities of such snacks. It is not being able to identify the right diet that makes fats to have the bad reputation.

As for carbohydrate they are found in a variety of different foods, some healthier than other. For instance, both Twinkies and whole wheat bread are sources of carbohydrates, but while one can form the basis of a healthy diet, the other is best used as an occasional snack. As with many products, less is often more when it comes to choosing foods rich in carbohydrates. For instance, less refined whole grain bread is generally more nutritious than white bread which has gone through a greater amount of refining. That is because the refining process tends to reduce nutrient content over time

Of course, in carbohydrates there are some elements in the diet that should be limited. Two of these elements are sugar and salt. Most Americans consume too much salt and sugar, and this has led to epidemics of obesity, diabetes, heart disease and other ills. Limiting sugar and salt, while choosing good fats and unrefined carbohydrates, is a great way to maximize the nutritional value of the foods you eat.
