What is Nutrition?
Nutrition is the science of food and how it affects our bodies. It’s a complex field that encompasses everything from the nutrients in our food to how our bodies absorb and use them. Good nutrition is essential for good health, and it can help us prevent or manage a variety of chronic diseases, such as heart disease, stroke, type 2 diabetes, and some types of cancer.
The Importance of Nutrients
Nutrients are the building blocks of our bodies. They provide us with the energy we need to function, as well as the materials we need to build and repair tissues. There are six essential nutrients that our bodies cannot produce on their own: carbohydrates, proteins, fats, vitamins, minerals, and water. We must get these nutrients from the food we eat.
- Carbohydrates are the body’s main source of energy. They are found in foods such as bread, pasta, rice, fruits, and vegetables.
- Proteins are essential for building and repairing tissues. They are found in foods such as meat, poultry, fish, eggs, dairy products, and beans.
- Fats provide energy and help the body absorb vitamins. They are found in foods such as butter, margarine, oil, nuts, and seeds.
- Vitamins are essential for a variety of bodily functions, such as vision, immunity, and blood clotting. They are found in fruits, vegetables, and whole grains.
- Minerals are also essential for a variety of bodily functions, such as bone health, muscle function, and fluid balance. They are found in foods such as meat, poultry, fish, dairy products, and leafy green vegetables.
- Water is essential for life. It makes up about 60% of our body weight and is involved in a variety of bodily functions, such as regulating body temperature, transporting nutrients, and removing waste products.
How to Get the Nutrients You Need
The best way to get the nutrients you need is to eat a healthy diet that includes a variety of foods from all food groups. The MyPlate plan is a good guide to healthy eating. MyPlate recommends that adults fill half of their plate with fruits and vegetables, a quarter of their plate with whole grains, and a quarter of their plate with lean protein. MyPlate also recommends that adults limit their intake of saturated and trans fats, cholesterol, and sodium.
If you have difficulty getting all of the nutrients you need from food alone, you may need to take a dietary supplement. Dietary supplements can provide you with extra nutrients, but they are not a substitute for a healthy diet. It’s important to talk to your doctor before taking any dietary supplements.

How to Make Healthy Eating Choices
Making healthy eating choices can be difficult, but it’s important to remember that small changes can make a big difference. Here are a few tips for making healthy eating choices:
- Start small. Don’t try to change your entire diet overnight. Start by making one or two small changes, such as adding a serving of fruit to your breakfast or lunch.
- Make gradual changes. Once you’ve made a few small changes, gradually make more changes over time. This will help you avoid feeling overwhelmed and make it more likely that you’ll stick with your new healthy eating habits.
- Find healthy alternatives. If you love unhealthy foods, don’t give them up completely. Instead, find healthy alternatives that you enjoy. For example, if you love fries, try baking them instead of frying them.
- Cook more meals at home. Cooking more meals at home gives you more control over the ingredients in your food. It also allows you to experiment with new healthy recipes.
- Read food labels. When you’re shopping for food, take the time to read the food labels. This will help you make informed choices about the foods you’re eating.
