Vitamins and minerals are needed in small amounts, but they matter for energy, bone health, immunity and recovery. Most people can meet their needs through a varied diet. Here is a beginner's overview of some commonly discussed nutrients and where they come from.
Key Nutrients and Common Food Sources
- Calcium: milk, curd, paneer, ragi, leafy greens
- Iron: leafy vegetables, pulses, dates, jaggery, meat and eggs
- Vitamin C: citrus fruits, guava, amla, tomatoes
- Vitamin D: sunlight exposure and some foods such as eggs and fortified products
- Vitamin B12: dairy, eggs and animal foods; vegetarians should be aware of this
- Magnesium and potassium: nuts, bananas, whole grains, vegetables
Why Variety Matters
No single food contains everything. Eating different colours and types of foods across the day helps cover many nutrients at once.
Are Supplements Needed?
Many people do not need supplements, but some groups may, such as people with diagnosed deficiencies or particular diets. Taking high doses without need can be harmful. Always consult a doctor before using them.
Signs That Need Medical Attention
Persistent fatigue, frequent illness, pale skin, hair loss or unusual cramps can have many causes. Do not self-diagnose. Speak to a doctor for tests and advice.
Putting It Into Practice
Aim for at least five portions of fruits and vegetables across the day, include whole grains and pulses, and include dairy or other calcium sources. Plan colourful plates rather than counting nutrients, and get periodic health check-ups, especially if you train hard.
Key Takeaways
- Variety covers most needs.
- Do not self-diagnose deficiencies.
- Consult professionals before supplements.
