The Cornerstone of a Healthy Lifestyle
Nutrition is the study of food and how it affects our bodies. It is a complex science, but understanding the basics of nutrition can help you make healthy choices that will support your overall well-being.
The Essential Nutrients
There are six essential nutrients that our bodies need to function properly:
Carbohydrates: Carbohydrates are the body's main source of energy. They are found in foods such as bread, pasta, rice, fruits, vegetables, and milk.
Proteins: Proteins are essential for building and repairing tissues. They are found in foods such as meat, poultry, fish, eggs, beans, and nuts.
Fats: Fats provide energy and help to store vitamins. They are also important for brain function. Fats are found in foods such as oils, nuts, seeds, and avocados.
Vitamins: Vitamins are essential for many bodily functions. They are found in small amounts in a variety of foods.
Minerals: Minerals are essential for building bones and teeth, regulating blood pressure, and carrying oxygen in the blood. They are found in a variety of foods, including fruits, vegetables, grains, and dairy products.
Water: Water is essential for life. It makes up about 60% of our body weight and is needed for many bodily functions, including digestion, circulation, and temperature regulation.
