However, it’s important to moderate the intake of saturated and trans fats, which can increase cholesterol levels and contribute to health problems.

Vitamins: Micronutrients for Vital Functions

Vitamins are essential for our bodies to function optimally, although they are required in smaller quantities compared to macronutrients. These micronutrients play a significant role in various bodily processes, such as metabolism, immune function, and cell production. Consuming a diverse range of fruits, vegetables, whole grains, and lean proteins can provide a wide array of vitamins necessary for maintaining good health.

Minerals: Building Strong Bones and More

Minerals are vital for maintaining the proper functioning of our bodies. They are involved in the formation of bones and teeth, regulating fluid balance, and supporting nerve and muscle function.
