Vitamins are essential nutrients that our bodies need to function properly. They support growth, immunity, and overall health. Since our bodies cannot produce most vitamins, we must obtain them from food or supplements. Understanding vitamins and their roles can help us maintain good health and prevent deficiencies.
What are Vitamins and Why Do We Need Them?
Vitamins are essential organic compounds required by the body in small amounts to maintain overall health and proper functioning. These nutrients are primarily obtained from food sources, as the human body either does not produce them or produces them in insufficient quantities. Vitamins play crucial roles in metabolism, immune support, cell growth, and overall well-being.
Types of Vitamins
Vitamins are organic compounds vital for maintaining overall health and bodily functions. They are divided into fat-soluble vitamins (A, D, E, and K) stored in fat tissues and water-soluble vitamins (C and B-complex) that require daily intake. Each vitamin plays a unique role in growth, immunity, and metabolism.
Fat-Soluble Vitamins and Their Sources
- Vitamin A: Found in carrots, sweet potatoes, spinach, liver, eggs, and dairy products.
- Vitamin D: Obtained from sunlight exposure, fatty fish (salmon, tuna), fortified dairy products, and egg yolks.
- Vitamin E: Present in nuts, seeds, vegetable oils, spinach, and avocados.
- Vitamin K: Found in leafy greens (kale, spinach), broccoli, soybeans, and fermented foods.
Water-Soluble Vitamins and Their Sources
- Vitamin C: Rich in citrus fruits (oranges, lemons), strawberries, bell peppers, and tomatoes.
- Vitamin B1 (Thiamine): Found in whole grains, nuts, pork, and legumes.
- Vitamin B2 (Riboflavin): Present in milk, eggs, green vegetables, and almonds.
- Vitamin B3 (Niacin): Found in chicken, fish, peanuts, and whole grains.
