What are vitamins and minerals?
Vitamins and minerals are essential micronutrients that play important roles in the human body. While vitamins are organic compounds that assist in various metabolic reactions, minerals are inorganic elements fundamental for cellular function, tissue structure, and various physiological processes.
Unlike macronutrients such as carbohydrates, proteins, and fats, which are needed in large amounts, vitamins and minerals are required in small quantities, but their absence can cause severe deficiencies and health impairments. Each of these nutrients has a specific function and works together to ensure that our body functions properly.
Main functions of vitamins and minerals
Micronutrients play a crucial role in overall well-being. Their main functions include:
- Strengthening the immune system: Some vitamins, such as C and D, help increase resistance against infections and diseases.
- Energy production and metabolism maintenance: B-complex vitamins help convert food into energy.
- Development and maintenance of bones, teeth, and skin: Minerals such as calcium and magnesium are essential for bone health.
- Cognitive function and mental health: Vitamins such as B12 and folic acid are essential for the proper functioning of the nervous system.
- Prevention of chronic diseases: Many antioxidants, such as vitamin E and selenium, combat oxidative stress and reduce the risk of degenerative diseases.
Key vitamins and their benefits
Vitamin A
Vitamin A is essential for eye health, skin, and immune system function. Its deficiency can cause problems such as night blindness and low immunity.
- Sources: Carrot, sweet potato, spinach, liver, mango.
Vitamin C
Vitamin C is a potent antioxidant that strengthens the immune system, improves wound healing, and helps the body absorb iron.
- Sources: Orange, kiwi, strawberry, bell pepper, acerola.
Vitamin D
Vitamin D is necessary for calcium absorption, preventing bone diseases such as osteoporosis. It also plays a role in immune function.
- Sources: Sunlight, fatty fish, egg yolk, fortified dairy products.
Vitamin E
Vitamin E is a powerful antioxidant that protects cells from oxidative damage and contributes to skin health.
- Sources: Nuts, seeds, olive oil, spinach.
B-Complex Vitamins
Essential for metabolism and nervous system health, these vitamins help produce neurotransmitters and convert food into energy.
- Sources: Whole grains, meat, dairy products, eggs, legumes.
Essential minerals and their functions
Calcium
- Essential for healthy bones and teeth, involved in muscle contraction.
- Sources: Milk, cheese, yogurt, leafy green vegetables.
Iron
- Necessary for hemoglobin formation and anemia prevention.
- Sources: Meat, beans, lentils, spinach, tofu.
Zinc
- Participates in healing, immunity, and protein synthesis.
- Sources: Seafood, red meat, seeds, legumes.
Magnesium
- Essential for muscle and nerve function, regulates blood pressure.
- Sources: Banana, nuts, spinach, dark chocolate.
How to ensure adequate intake of vitamins and minerals
- Maintain a balanced diet with fruits, vegetables, whole grains, and lean proteins.
- Avoid ultra-processed foods, which have few micronutrients.
- Consider supplementation only under the guidance of a healthcare professional.
- Drink plenty of water, as hydration influences nutrient absorption.
- Get safe sun exposure to maintain adequate vitamin D levels.
Conclusion
Vitamins and minerals are fundamental for health and well-being. A varied diet rich in these micronutrients is the best way to avoid deficiencies and ensure proper bodily function. Small changes in eating habits can bring significant long-term benefits.
