II. Major Nutrients: Building Blocks for a Healthy Body

A balanced diet is essential for maintaining a healthy body and mind. The major nutrients that our bodies need are carbohydrates, proteins, fats, vitamins, and minerals. Each of these nutrients plays a vital role in our overall health and well-being.

Carbohydrates: The Body’s Main Source of Energy

Carbohydrates are the body’s primary source of energy. They are found in foods such as bread, pasta, rice, potatoes, fruits, and vegetables. Carbohydrates are broken down into glucose, which is then used by the body for energy. Complex carbohydrates, such as those found in whole grains, take longer to digest and provide a more sustained source of energy than simple carbohydrates, such as those found in sugary foods.

Type of Carbohydrate	Sources	Benefits
Simple Carbohydrates	Sugar, candy, white bread, white rice	Quick energy boost, but can lead to blood sugar spikes and crashes
Complex Carbohydrates	Whole grains, fruits, vegetables, legumes	Sustained energy, helps regulate blood sugar levels, provides fiber

Here are some tips for incorporating more healthy carbohydrates into your diet:

• Choose whole grains over refined grains whenever possible.
• Eat plenty of fruits and vegetables.
• Limit your intake of sugary foods and drinks.

Proteins: The Building Blocks of Life

Proteins are essential for building and repairing tissues, producing hormones and enzymes, and transporting nutrients and oxygen throughout the body. Proteins are found in foods such as meat, poultry, fish, eggs, dairy products, beans, and nuts. Complete proteins contain all nine essential amino acids that the body cannot produce on its own. Incomplete proteins contain some, but not all, of the essential amino acids. By combining different protein sources, you can ensure that you are getting all of the essential amino acids that your body needs.

Type of Protein	Sources	Benefits
Complete Proteins	Meat, poultry, fish, eggs, dairy products	Contain all nine essential amino acids
Incomplete Proteins	Beans, lentils, nuts, seeds	Contain some, but not all, of the essential amino acids

Here are some tips for incorporating more protein into your diet:

• Eat a variety of protein sources throughout the day.
• Include protein in every meal and snack.
• Choose lean protein sources, such as fish, poultry, and beans, over fatty protein sources, such as red meat and processed meats.
