What is Nutrition?
Nutrition is the study of how food affects our bodies, health, and overall well-being. Proper nutrition provides us with the energy we need to perform daily activities, helps our bodies grow and repair, and keeps our immune system strong. Without proper nutrition, our bodies cannot function optimally, leading to fatigue, poor concentration, and a higher risk of illnesses.

Fats: Important for storing energy and protecting organs. Found in oils, butter, and avocados.
Vitamins: Help regulate body processes. Found in fruits, vegetables, and dairy products.
Minerals: Essential for various bodily functions. Found in meat, cereals, fish, and dairy.
Water: Vital for every bodily function, including digestion and temperature regulation.
Homework: Keep a food diary for one day. Record everything you eat and drink, including portion sizes.
