I have intolerance to many foods, one of which is polyunsaturated fats.
I discovered through this forum that frying in certain animal fats, not only enhances the full English but the benefits to health of it are multiplied.
Saturated fat does not make you fat, I am a living guinea pig, my food diary has details of how much difference avoiding certain so called 'healthier' cooking oils!
As for nitrates, if you have a choice like I do, I use gammon grilled instead of the bacon. If you go to a market, you can find healthier options in sausage, sourced protein, eggs, dairy!
The supermarkets are getting wiser to certain intolerant groups like gluten.
I just wish that, the usual suspects would stop the constant dissing of what is a healthy traditional meal.
