Good nutrition is important in keeping people healthy throughout their lives - when they are babies, toddlers, children, adults, and then older adults. It can help people live longer and lower their risk of health problems like heart disease, type 2 diabetes, obesity, and more.
Good nutrition is about healthy eating. This means regularly choosing healthy foods and beverages. A healthy eating plan should give your body the energy and nutrients that you need every day. Nutrients include proteins, carbohydrates, fats, vitamins, minerals, and water. The plan should also take into account your preferences, cultural traditions, and budget.
Healthy eating does not mean that you have to follow a very strict diet or eat only a few specific types of food. It doesn’t mean that you can never eat your favorite foods. You can eat a variety of foods, including less healthy favorites. But it’s important not to eat too much of those foods or have them too often. You can balance those foods with healthier foods and regular physical activity.
The keys to a healthy eating plan include:
Eating a variety of foods, including vegetables, fruits, and whole-grain products
Eating lean meats, poultry, fish, beans, and low-fat dairy products
Getting enough fiber
Drinking lots of water
Limiting salt, added sugars, alcohol, and saturated fat
Making sure that you get enough nutrients, especially calcium, vitamin D, and potassium
