Namak: thoda dost, zyada dushman
Chips ka packet meetha nahi, namkeen hota hai. Par kya tumhe pata hai tumhara shareer namak ke bina chal hi nahi sakta?
Socho pehle… phir dekho jawab
Namak mein sodium hota hai, jo nerves (nason) ke message bhejne, muscles chalane aur shareer mein paani ka balance rakhne mein madad karta hai. Par zyada namak lambe samay mein blood pressure badha sakta hai.
Khaane mein carbohydrate, protein, fat, vitamin ke saath minerals bhi hote hain. Namak ek zaroori mineral deta hai. Pasina aata hai toh namak bhi bahar nikalta hai — isiliye pasine ka swaad khaara hota hai.
Dikkat tab hai jab namak bahut zyada ho jaaye. Zyada namak se shareer paani rokta hai aur khoon ki nasoon pe dabaav badh sakta hai. Isse high blood pressure kehte hain, jo dil ke liye accha nahi.
Chupa hua namak sabse bada chor hai: chips, namkeen, achaar, papad, instant noodles, sauce. Dal-sabzi mein daala namak toh dikhta hai, par packet waala namak chupke se aata hai.
Ghar pe try karo
Ghar mein 3 packet waali cheezon ke peeche ka label dekho. 'Sodium' kitna likha hai? Kaunsa sabse zyada hai? Family ko bata do — aur khaane ki mez pe alag se namak ki shaker pe ek din break lagao.
Wow!
Zubaan ko namak ki aadat hoti hai — dheere-dheere kam karo toh kuch hafton mein kam namak bhi utna hi tasty lagne lagta hai.
