hello @
Macronutrients are the nutrients that give your body energy to perform essential functions. The word "macro" means large, and these nutrients are needed in large quantities. The three macronutrients are fats, carbohydrates, and proteins. Each of these nutrients provides calories and helps you carry out essential functions like walking, thinking, converting food into energy, growing, and repairing yourself.
Each macronutrient is essential to life, and each provides a certain amount of calories. Fat is the most calorie dense nutrient, providing 9 calories per gram. Carbohydrates and protein both provide 4 calories per gram.
Micronutrients are also essential to your body, but you need smaller amounts. The word "micro" means small, so you need smaller amounts of micronutrients than of macronutrients. Micronutrients are usually called vitamins and minerals. There are 28 essential micronutrients your body needs to survive. There are also many other vitamins and minerals that perform important functions, but you would probably be able to live without them. If your diet does not supply enough of the critical micronutrients, your body will use up any storage supplies of the vitamin or mineral (which can cause bone loss and muscle wasting). You can experience vitamin deficiency diseases like scurvy and pellagra.
Here's an astounding fact: People can actually eat so much food that they become overweight or even obese, but if their diet is made up of over-processed "junk" food with little nutritional value, they could suffer from a nutritional deficiency. It is possible to be overweight and malnourished at the same time; that's why it's so important to understand basic nutritional principles.
Alcohol
Alcohol also contributes energy to the body; it contains 7 calories per gram. However, alcohol does not provide any nutritional benefits, so it is not considered a nutrient.
