The Building Block of Nutritions
Our bodies rely on essential nutrients to fuel energy, growth, and health. There are two types of nutrients:
Macronutrients:
- Carbohydrates: Main source of energy. Found in grains, fruits, and vegetables.
- Proteins: Needed for growth and repair of body tissues. It is found in meat, beans, and dairy.
- Fats: Important for brain health and energy storage. Found in oils, nuts, and avocados.
Micronutrients:
- Vitamins: Help with immune function, skin health, and energy production (e.g., Vitamin C, Vitamin D).
- Minerals: Important for bone health, nerve function, and hydration (e.g., calcium, iron).
How Nutrients Work in Our Bodies
Our bodies transform nutrients into energy, strength, and essential support for daily functions.
- Digestion: Nutrients are broken down in the stomach and intestines to be absorbed into the bloodstream.
- Energy Production: Carbohydrates are converted into glucose, a sugar that fuels cells, especially in the brain and muscles.
- Repair and Growth: Proteins are broken down into amino acids, which help build muscles, skin, and organs.
- Storage and Insulation: Fats are stored for long-term energy use and help protect organs.
Fun Facts
Here are some interesting facts about nutrition:
- About 60% of the brain is fat, so omega-3-rich foods like fish and walnuts are known as “brain food.”
- Blueberries, spinach, and nuts are considered “superfoods” because of their high nutrient content.
- We get about 20% of our daily water from food.
- Bell peppers have even more Vitamin C than oranges, making them a powerful immune booster!
