Takeaways

• 😀 Carbohydrates are the main source of energy for the body, providing 4.1 calories per gram. Sources include fruits, vegetables, rice, potatoes, and cassava.
• 😀 Fats are essential for energy, providing 9.4 calories per gram, and also help in cell membrane formation and vitamin absorption. They come from both animal and plant sources.
• 😀 Proteins are crucial for growth, cell repair, and energy production. They provide 4.1 calories per gram and are found in both animal (eggs, milk, meat) and vegetable (nuts) sources.
• 😀 Vitamins are organic substances vital for body processes. They are divided into fat-soluble (A, D, E, K) and water-soluble (B, C) categories.
• 😀 Vitamin A is essential for eye health and skin, with sources including liver, egg yolk, and orange/yellow fruits.
• 😀 Vitamin D helps absorb calcium and supports bone health. Sources include egg yolk, milk, and fish oil.
• 😀 Vitamin C supports protein breakdown, adrenal function, and immune health. It is found in fruits like oranges, strawberries, and tomatoes.
• 😀 Minerals, such as iron, calcium, phosphorus, and iodine, are essential for body structure, red blood cell formation, and metabolic functions.
• 😀 Water plays a critical role in maintaining body temperature, supporting chemical reactions, and carrying substances through the body.
• 😀 A balanced diet that includes adequate carbohydrates, fats, proteins, vitamins, minerals, and water is essential for overall health and well-being.

Q & A

What is the role of proteins in the body and what are their sources?

Proteins are essential for growth, repairing damaged cells, building enzymes, and providing energy. They are found in both animal sources like eggs, milk, and meat, and vegetable sources like nuts.

What are the effects of vitamin A deficiency?

Vitamin A deficiency can lead to night blindness, corneal damage (keratomalacia), and scaly skin.

How does vitamin D support the body and where can it be found?
