Ancient Ayurveda says one good line, its like this –>>
“रोग आहर संभव: शरीरस्तु अन्नपानमूला II”
It means, our food is essential conent of body, Our body built up on food and unwanted/bad food creates various diseases in our body.
So choose your food wisely and be healthy.Consume food as a Medication so you dont need to take medicines. Ayurveda not only teaches how to treat the diseases but it says us how to maintain our Health nicely.
