There are two types of carbohydrates. Simple carbohydrates are found in fruits and fruit juice and are easily digested by the body. They are also found in processed foods and anything with added refined sugar, such as cakes and sodas and candy. Complex carbohydrates are found in almost all plant-based foods and usually take longer for the body to digest. They are commonly found in whole-wheat bread, whole-grain pasta, brown rice, and starchy vegetables like corn.
If the foods you eat contain too many carbohydrates, they are stored in the liver and muscle cells and are used when the body needs an extra amount of energy. Anything leftover is turned into fat. However, if you don't eat enough carbohydrates, you can become fatigued, get muscle cramps, or may suffer from poor mental function.
A low-carbohydrate diet might seem healthy but if taken too far, it can be dangerous to a person's overall well being. It is important to remember that "low carb" does not mean "no carb". Make sure to eat moderate amounts of carbohydrates to keep your body fueled properly, with 50-55 percent of calories coming from carbohydrates.
Fat is an essential nutrient and should be part of balanced diet. Fat provides energy, energy storage, insulation and contour to the body. There are several types of dietary fat. It is important to choose good fats like olive oil, oily fish, nuts, seeds, and avocados, and less of the saturated fats from animals, fried foods and hydrogenated oils. According to the World Health Organization, we should restrict our dietary fat intake to 30 percent of our calories. It is recommended that no more than 7-10 percent is from saturated fat.
Proteins are the basic building blocks of the human body. They are made up of amino acids and help build muscles, blood, skin, hair, nails, and internal organs. Protein provides valuable enzymes that regulate bodily functions. It is the key to muscle building and development. There are different types of protein. Animal proteins are complete and contain all the essential amino acids that your body needs. Vegetable proteins like legumes, seeds and nuts are considered incomplete proteins because each individual food does not contain all of the essential amino acids, so you need to combine them and eat a variety to get what your body needs.
Other important components of a healthy lifestyle include getting plenty of sleep, staying hydrated and exercising regularly.
