I eat some cheese (about half a pound in a month)

I stopped drinking juice about six months ago.  But I drink a little bit coffee, a little bit tea, quite some yogurt smoothie and milk.

I have not used olive oil for years now simply because there is so much olive oil on the market and it is hard to choose which.  I have been using expeller-pressed sunflower oil and walnut oil.

I don;t eat that much cheese, as you can see.  Usually in a grilled-cheese sandwich.  But I do have yogurt and yogurt smoothie.

I guess food can be a factor.  Brain activity is also a factor.

Thanks for giving me all these information.  I really appreciate it. I guess there is not one simple exact cause.
