Fats and carbohydrates are two building blocks of a healthy diet, but many people do not understand their role in proper nutrition. While the daily intake of fats and oils should be limited, these elements are still a vital part of the diet. The key is to make smart choices when it comes to fats and oils. That means substituting saturated fats with unsaturated fats, and using healthier, lighter oils in cooking.

Let’s look at the role fats and oils play in the diet. Fats are necessary for supplying energy to the body. In addition, fats supply essential fatty acids and act as carriers for fat soluble vitamins like vitamin A, vitamin D, vitamin E, vitamin K and the carotenoids. In addition, fats have an important role to play as building blocks for various tissues and membranes, and they also play a key role in regulating numerous bodily functions.

Dietary fat is available from a variety of plant and animal sources, and most diets do contain adequate amounts of fat. Most nutrition experts recommend keeping the intake of fat to less than 20% of calories, but studies have shown that severely limiting fat intake can be dangerous. Extreme low fat diets should only be undertaking with a doctor’s approval and oversight.

The type and amount of fat in the diet makes all the difference. A diet high in saturated fats, trans fats and cholesterol has been associated with a variety of ills, including heart disease, stroke and other associated diseases. In addition, many long term chronic problems, such as obesity, are associated with high levels of dietary fats.

The greatest risk of complications from excessive fat intake appears to lie with saturated fats and trans fats (fats that are solid at room temperature). One of the best ways to keep levels of saturated fat low is to limit the amount of animal fats that are consumed. These animal based fats include meats like bacon and sausage, as well as butter and ice cream. Dietary cholesterol can be limited by watching the consumption of eggs, organ meats and other foods high in cholesterol.

Food labels do make the complicated process of choosing the right fats somewhat easier. For instance, trans fats will be listed on the ingredient list of foods that contain them. In general, trans fats are found mainly in processed foods.

Some fats, such as polyunsaturated fats and monounsaturated fats, are better choices for healthy eating. Examples of these fats include canola oil and olive oil. Cooking with these lighter oils can be a big step toward a healthier diet. Polyunsaturated and monounsaturated fats are liquid at room temperature, and they have been found to have heart protecting qualities.

Many types of fish have also been found to be sources of good fat. Fish are excellent sources of omega-3 fatty acids. These omega-3’s have been found to promote good health, and they may even lower cholesterol levels.

Carbohydrates are an important part of a healthy diet as well, and carbs are necessary for providing energy and many essential nutrients. Carbohydrates are found in fruits and vegetables, in grains and in milk and dairy products. It is important to choose carbohydrates carefully, however, since not all are equally healthy.

When choosing breads and cereal, for instance, try to select those made with whole grains, while avoiding the more highly refined varieties. It is also important to limit the intake of sugars, such as soda, candy and highly processed baked goods. Consuming large amounts of such high calorie, low nutrient foods, can make it very difficult to stay on a healthy diet without gaining weight.

Most Americans tend to have too much of certain elements in their diet. Sugar is one such element and salt is the other. While a basic level of sodium in the form of salt is important to proper nutrition, most people consume too much salt in their daily diet. Excess salt consumption can lead to water retention, high blood pressure and other complications. Choosing low sodium foods, and limiting the use of the salt shaker, can go a long way toward cutting levels of excess salt in the diet.

Recent changes in food guidelines have meant an increase in the recommended daily consumption of fruits and vegetables. That is because eating nutrient rich, low calorie, low fat foods such as fruits and vegetables, has been shown to have a strong impact on overall health.

In addition, high levels of fruits and vegetables in the diet has even been shown to help provide protection from a number of diseases and chronic conditions. There are ongoing studies on the relationship between a diet rich in fruits and vegetables and prevention of cancer, diabetes, heart disease and other conditions. While there may not yet be conclusive proof of a link between fruits and vegetables and lower risk of disease, there is ample anecdotal evidence to suggest that a healthy diet leads to a healthy body.

One reason for the strong health benefits of fruits and vegetables is their strong antioxidant qualities. Many fruits and vegetables are high in important antioxidant vitamins like vitamin C, vitamin E and vitamin A. In addition, fruits and vegetables contain lots of other nutrients and trace elements that are important to the proper function of the body.

Choosing the best fruits and vegetables is important, both to your health and the health of your food budget. We all have limited food budgets, and getting the best in terms of both taste and nutrition, is very important.

One way to get maximum value and maximum nutrition is to choose fresh, in season fruits and vegetables. That is because fresh, locally grown fruits and vegetables tend to be less expensive than their shipped counterparts.

If you have a farmers market or produce stand nearby, it can be an excellent source of the highest quality, lowest cost fruits and vegetables. Summer produce stands are excellent sources of delicious and nutritious fruits and vegetables.

In addition, buying fruits and vegetables as they come into season will instantly provide you with variety. There are literally hundreds of different varieties of fruits and vegetables at the average grocery store, and they all have different growing season. Buying the fresh in season fruits and vegetables is a great way to introduce yourself to some varieties you may never have tried before.

Of course there will be times when your favorite fruits and vegetables are not available locally. In those cases, frozen and canned varieties can do just fine. Just about every popular fruit and vegetable is available canned or frozen, and these can make wonderful, fast fruit salads or quick snacks.

It is important to choose fruits and vegetables in a variety of colors, and not only for ascetic reasons. Different colored fruits and vegetables contain different types of nutrients, and different levels of nutrients, so eating a good variety of green, gold, orange and purple is the best way to ensure adequate levels of nutrition.

How you cook the vegetables you buy is important as well. Over cooking can destroy many of the nutrients that make vegetables so healthy. Fortunately, most vegetables can be cooked by quickly steaming them in the microwave or on the stovetop.

How those cooked vegetables are served can also have a significant impact on their healthiness. Adding butter, margarine, oils or other fats to vegetables can quickly negate their health benefits. Better choices for seasoning cooked vegetables include fruit juices and low fat yogurt.

Most nutrition experts recommend that everyone eat from 5 to 9 servings of fruits or vegetables every day. While that may seem like an impossible goal, it is easier when you understand just what a serving consists of. One serving of a fruit or vegetable can be one medium sized piece of fruit, one slice of melon, two small pieces of fruit, one cup of strawberries, one cup of grapes, one half cup of canned fruit, one half cup of fruit salad, one side salad or one half cup of fresh fruit juice.

With all these choices to choose from, it is easy to see why fruits and vegetables are such a popular part of a healthy diet. No matter what your reason for pursuing healthy eating, fruits and vegetables are a healthy addition to any diet.
