Why are some people more prone to bad breath from foods than others?

I’ve always noticed that msot people can eat spicy curries rich in garlic and onions everyday but not get bad breath or halitosis like i do!

do you have some sort of gum disease? because bad breath a lot of times is caused by some kind of disease in the gums. like some one else said, if you like curry keep eating it. but maybe you should go your dentist to find out what the cause of your smelly breath is. just make sure that brush and floss your teeth everyday. keep your mouth hydrated by drinking a lot of water.

What does rancidity smell like? Does it smell similar to halitosis by any chance?

Do all rancid foods give off the same scent? I made some homemade granola that I eat every morning at work. I added some ground-up flax seeds because of their apparent health benefits. On the third day eating from this batch I noticed a weird aftertaste — really an ‘aftersmell’ – reminiscent of bad breath (the halitosis kind, which I normally don’t have, mind you). I recall reading that flaxseeds (and other seeds too I think) are prone to becoming rancid. So I am wondering if perhaps I am smelling something slightly rancid in my granola.

You had best make it fresh every day and keep the ingredients in a cool place.

Flax seeds have a lot of oil and also protein in them. This can be affected by bacteria and fungus (can actually be dangerous if you don’t keep it safely).
