Khaane mein kai poshak tatva (nutrients) hote hain, har ek ka kaam hai. Carbohydrates (chaawal, roti, aaloo, gud) aur fats (ghee, tel, mewe) urja dete hain. Proteins (daal, paneer, anda, machhli, soya) shareer ko badhne aur marammat mein madad karte hain.

Vitamins aur minerals thodi maatra mein chahiye par hamein swasth rakhte aur beemaari se bachaate hain. Vitamin A (gaajar, papita) aankhon ke liye, vitamin C (aamla, amrood) masoodon ke liye, vitamin D (dhoop!) aur calcium (doodh, ragi) haddiyon ke liye, iron (paalak, gud) khoon ke liye, iodine (iodine wala namak).

Phal, sabzi, saabut anaaj aur daal ka dietary fibre (roughage) poshan nahi deta, par khaane ko shareer mein aaraam se aage badhaata hai. Paani poshak tatva le jaata hai, paachan mein madad karta hai, kachra nikaalta hai aur thanda rakhta hai.

Jab lambe samay tak khaane mein kisi poshak tatva ki kami ho, to kami se hone wali beemaari ho sakti hai: vitamin C kam → masoodon se khoon (scurvy); vitamin D → kamzor, mudi haddiyaan (rickets); iodine → gale ki soojan (goitre); iron → thakaan (anaemia). Tarah-tarah ka khaana inse bachaata hai.

1. Urja, shareer banaane wala ya suraksha?

Yaad rakho

• Carbohydrates aur fats urja dete hain; proteins banaate aur marammat karte hain; vitamins aur minerals suraksha dete hain.
• Fibre aur paani bhi zaroori hain. Lambe samay tak kisi tatva ki kami se beemaari hoti hai.
