I don't follow the food combining that much because I rarely eat grains. I do take HCI with pepsi which helps with digestion if I do eat meat. Grains (breads, soy products, potatoes,, rice, corn yes corn is a grain etc) are energy source for bacteria. You see all foods have bacteria unless you all foods most bacteria will survive. Even then water has bacteria. My best friends who used to repair water meters had to learn all about water and it's safety. He told me all water has bacteria unless you boil them in extremely high heat. Those carbon filters don't filter out bactieria what you need to get is reverse osmois water filter unit or Ionize water machine. These will kill most of the bacteria.
If you're not allergic to yogurt and milk doesn't make your bloat cause mucus production. You should make cultured yogurt. Culture yogurt has live bacteria that kills those unfriendly bacteria in your colon. When there's too many bad bacteria inthe body and you eat some grains the parasites produces gas.
Best to eat vegetables and some fruits (not the too sweet ones. I wouldn't advise you to eat any kind of meat except fish if it's doesn't have murcury in it. Otherwise you can have almonds or make almond bread.
Soda pop and artiifical sweetners is pure poision and will make you have heart burn also. Best not to eat any processed foods period
I also take fish oil, not the cheap brand get them at your health food store and only cook with coconut oil. These are inflamatory to your body and very benefical to your health. Also eat small meals and chew your foods very well. Lack of chewing makes your stomache work harder digesting foods. I found HCI with pepsin to help a lot. I notice a difference first day when I eat some chicken.
You should consume some unrefined sea salt, it has many minerals. Also I take coral calicum with vitamin d. I suggest you start off small and work your way up.
