How many major nutrients does food contain?

Food contains three major nutrients – carbohydrates, protein and fat. Let’s go through each.

Carbohydrates

Carbohydrates are the body’s main source of energy. Many of the carbohydrates we eat are converted into sugar in the body, and therefore, can raise glucose levels. The total amount of carbohydrates eaten has a greater effect on glucose levels than the type of carbohydrates consumed. Carbohydrates are measured in grams. On average, about half of the calories we consume each day come from carbohydrates.

Protein

Protein is broken down into amino acids. Amino acids are used to repair and replace body tissues. Protein
has much less effect on your glucose levels than carbohydrates. It does not easily turn into glucose.

Protein is found primarily in meat, fish, poultry, eggs, cheese, milk, nuts and dried beans. It is recommended that you eat 2-3 servings per day. Select lean meats, poultry, and low-fat or fat-free dairy and beans (remember that some dairy choices and beans count as carbohydrates, too).

fats

A small amount of fat in the diet is necessary to maintain good health. However, most of us consume
more fat than we need. There are different types of fat. Some fats are healthier than others. Too much
saturated and trans fat increases your risk for heart disease. It can also cause weight gain and insulin
resistance. Updated guidelines suggest following a more “Mediterranean” way when choosing healthy
fats (monounsaturated and polyunsaturated) in the diet. Eating more foods like salmon (fatty fish),
avocados, nuts (almonds, walnuts, pistachios), flaxseed, wheat germ and using canola, olive or avocado
oils when cooking.
