Human Nutrition and Heart Health This is an example essay. The total word count on this essay is 683 words.

Nutrition is the word used to describe the types of materials that a human body needs. The people who study nutrition are called nutritionists. Nutritionists will group food into different categories depending upon what types of vitamins or minerals, or other substances are in the foods. The main groups of foods are fruits, vegetables, meats, dairy, carbohydrates and lipids (Lipids are also known as fats). The first food group, fruits, are usually pretty high in their vitamin and mineral contents, but usually pretty low in fat. Examples of fruits are foods like apples, bananas, pears, and cherries. The second food group, veg etables, also have a lot of vitamins, but they are an especially good source of minerals. Foods like broccoli, carrots, onions, and peppers are usually very low in fat and carbohydrates so it s okay for people to eat a lot of these types of foods. The meats category of foods includes foods that come from the muscle or organs of once living animals. These are foods like steak, chicken, and fish. The meat category of foods are a very good source of protein, which is really important if you want to grow big and strong. Eating some types of meat, called red meat, like steak and hamburger, is a good source of the mineral iron which is really important to how a new baby grows. Because of this, it is really important for women who are pregnant to consider eating meat. Dairy products are the types of foods that come from milk. There are a lot of different types of dairy products, such as milk that you drink, ice -cream, yoghurt and cheeses. Dairy products have some vitamins, and are a really good source of some types of minerals, especially calcium. Because calcium is a really important mineral in how bones are built, it s important that young people eat enough dairy products when they are growing. Even though ice cream is a dairy product, you probably shouldn t eat too much of it because it s high in lipids (fats). Carbohydrates and lipids both give us energy. Carbohydrates come in two types, simple and complex. Simple carbohydrates are like just plain sugars, like the kind of sugar that my mom and dad put in their coffee, or the kind of sugar that some people dip strawberries in. Simple carbohydrates are really common in things like candy and cakes, cookies and soda pop. Complex carbohydrates are found in foods like potatoes and rice and breads. Nutritionists usually say that complex carbohydrates are better than simple carbohydrates, so we should try to eat less candy and more breads and potatoes and rice. Lipids are fats. You can find fat in a lot of different things. There i s fat dairy foods and meat foods and some types of plants produce fat too. Pretty much any type of oil is also a fat.

For humans to be healthy, we should eat lots of the right kinds of foods. Usually, we re supposed to try to eat less simple carbohydrates and lipids and more of the foods that are fruits and vegetables because these foods have less fat. The reason why having less fat is good, is because if you eat too much fat and you don t get enough exercise, the fat can build up inside your circulat ory system. The fat can get stuck to the inside of your arteries and veins like glue. When there s too much fat inside your arteries and veins, it makes your hear work really hard. Doctors call this heart disease. If you have heart disease for too long, it s possible to have a heart attack, which might kill you. To be safe, and not have a heart attack, it s really important that people have good nutrition. This means that they should eat a good balance of food, with lots of vegetables and fruit, and some meat and carbohydrates, but you should stay way from eating too many lipids (fats). It s okay to eat nice tasting food like ice-cream and candy once and a while, but mostly, you should eat a balanced diet to stay healthy.
