Vitamins, minerals, and nutrients are essential substances that our bodies need to function properly.
- Vitamins are organic compounds that our bodies cannot produce in sufficient quantities, so they must be obtained through diet. They are categorized into two types: water-soluble vitamins (like vitamins C and B) that dissolve in water, and fat-soluble vitamins (like vitamins A, D, E, and K) that dissolve in fat.
- Minerals are inorganic elements present in small amounts in our bodies but essential for health. They include macrominerals (like calcium, magnesium, and potassium) and trace minerals (like iron, zinc, and selenium).
- Nutrients encompass all vitamins, minerals, and other essential elements such as amino acids, essential fatty acids, and antioxidants. They are vital for nourishing our cells, regulating body processes, and maintaining vitality.
Vitamins, minerals, and nutrients perform various essential functions in our bodies:
- Metabolism and energy production: B vitamins, for example, are crucial for carbohydrate, protein, and lipid metabolism, participating in the production and storage of energy for the body.
- Immune system: Nutrients like vitamin C, zinc, and selenium contribute to immune function, helping to maintain health.
- Bone and dental health: Calcium, vitamin D, and magnesium are essential for the development and maintenance of strong bones and teeth.
- Cell protection: Vitamins A, C, and E, along with selenium, act as antioxidants, protecting cells against oxidative stress caused by free radicals.
- Cognitive and nervous system function: Magnesium, iron, and B vitamins support normal cognitive and psychological functions.
- DNA synthesis and repair: Vitamins B12 and B9 (folate) play a key role in red blood cell production and DNA synthesis, essential for growth and cellular repair.
A balanced and varied diet is the best source of essential vitamins, minerals, and nutrients. Here are some examples of foods rich in these elements:
- Vitamin A: Found in carrots, sweet potatoes, spinach, and liver.
- B Vitamins: Found in meats, fish, eggs, dairy products, legumes, whole grains, and green vegetables.
- Vitamin C: Abundant in citrus fruits, strawberries, kiwis, bell peppers, and leafy greens.
- Vitamin D: Synthesized by the skin when exposed to sunlight; also found in fatty fish, eggs, and fortified dairy products.
- Vitamin E: Found in vegetable oils, nuts, seeds, and green vegetables.
- Vitamin K: Found in leafy green vegetables, broccoli, and cabbage.
- Calcium: Primarily in dairy products, leafy greens, and fortified beverages.
- Magnesium: Abundant in nuts, seeds, whole grains, and green vegetables.
- Iron: Found in red meat, liver, legumes, spinach, and fortified foods.
- Zinc: Found in meats, seafood, seeds, and dairy products.
- Selenium: Primarily in Brazil nuts, seafood, meats, and grains.
