The key is to not to overeat either one of these to the point that they are not healthy for you. 

Many people do not understand the role that fats and carbs play in our diet. 

While these should be limited, they are still important for a healthy lifestyle. 

The key is to make smart decisions when it comes to choosing which fats and oils you are going to eat. 

This means that you will want to substitute saturated fats with unsaturated fats. 

You want to cook with lighter oils when cooking.

Fats are essential for supplying the body with energy. 

Fats are essential so that fatty acids and aid in the transportation of fat-soluble vitamins around the body. 

These fat-soluble vitamins include:

  1. Vitamin A
  2. Vitamin D
  3. Vitamin E
  4. Vitamin K
  5. Carotenoids


Fats are also the building blocks for many tissues and membranes. 

They play many roles in regulating the various bodily functions.

Dietary fat is available in both plant and animal sources of food. 

Many nutrition experts recommend that the intake of fat should be kept to less than 20% of calories. 

Extreme low fat diets, however, are not safe and cause damage to the body. 

The type of fat that you take in also makes a huge difference. 

A diet that is high in saturated fats, cholesterol and trans fats have been associated with numerous conditions including:

  1. Heart disease
  2. Heart attacks
  3. Stroke
  4. Chronic health problems
  5. Diabetes
  6. Obesity


Excessive fat intake of saturated fats and trans fats are associated with the greatest complications. 

Trans fats are those fats that are solid at room temperature. 

One of the best ways to limit the intake of saturated fat is to limit the intake of animal fat in the diet. 

Cholesterol can be regulated by watching the intake of eggs and organ meats, as well as other foods that are known to be high in cholesterol. 

Food labels can make it difficult to determine which fats are good fats. 

For example, trans fats are listed on the ingredient lists and not in the chart of dietary information. 

Processed foods contain more trans fats.

Polyunsaturated and monounsaturated fats are better choices. 

These can be found in canola and olive oil. 

These are lighter oils and it is a big step towards healthier eating if you incorporate these into your diet instead of using fats such as lard to cook with. 

These fats are liquid at room temperature. 

They also have heart-protecting qualities, unlike trans fats.

Fish also contain good fats. 

They are a source of omega-3 fatty acids. 

These have been found to help lower cholesterol and to promote good health. 


These are important of a healthy diet, although the marketing of some diets may have you think otherwise. 

They are necessary for providing your with energy as well as essential nutrients. 

Carbohydrates are found in a variety of foods including fruits, vegetables, grains and dairy products. 

They are not all equally healthy, so it is important that you choose wisely. 

When you are choosing your breads and cereals, look to have them made with whole grains, while avoiding the more highly refined varieties. 

It is also important to limit the intake of sugars, such as baked goods and candy.

Carbohydrates are found in a lot of foods. 

For instance, cookies and whole wheat bread are both sources of carbohydrates.

This is where the importance of good decisions comes into play.

In addition to cereals and breads, carbohydrates are also present in fruits and vegetables. 

They are also available in dairy products.

These are produced in the body naturally and as a consequence of natural bodily processes. 

Most of the time the body will be able to neutralize and eliminate free radicals on its own. 

Stresses such as environmental pollution, a weak immune system, UV radiation and alcohol cause the body to not be able to effectively fight these free radicals.

 Excessive free radicals in the human body can cause damage to the structure and function of the various organs and other systems in the body. 

Recent studies have also shown free radicals cause a number of diseases. 

They may also play a role in aging. 

It is estimated that foods have about 4,000 different compounds that have antioxidant qualities.
