Stir Fried Oyster Mushrooms

I'm not sure. In fact, I am rather confused about, what is healthy cooking for healthy living. Seriously guys,  I can't comprehend and I really don't know how should I go about explaining healthy cooking and healthy eating (Moringa/Drumstick Leaves Stir Fried). For me personally, I eat anything. Anything in other words, everything in moderation and I do, from time to time, indulge in sinful guilty food pleasures. Of course, not gawking those heavy duty rich food daily, but when the craving kicks in. I am really fine. No guilty feeling due to me not the pigging out kinda and me exercising regularly. Still, trust me, controlling my weight and also, avoiding tiredness, body pain and headache which every now and then can literally pull me down? Not an easy feat for Nava K who is 54, going 55.
