Can you suddenly develop an intolerance to certain foods?

[OrchidLass]

At the age of 47? I've noticed over the last week or so, if I have bread/toast or cereal with milk for breakfast I'm doubled up in pain and running to the toilet within about 15/20 minutes. I've only just realised its when I have certain things, can you suddenly just become intolerant or am I totally barking up the wrong tree?

DH developed an intolerance to gluten and lactose in his 40s, not made up, full on investigations with gastroscopy and endoscopy to rule out anything more sinister.

The other point is that allergies can be aggravated by stress, so if you are under chronic and prolonged stress, it can have quite a pronounced effect on how you react to certain foods.

ppeatfruit - yes, still following it! It made such a difference to me that I'll never go off it. Although something that previously hadn't caused me bother is now giving me acid so I need to work out what. Since I started with the basics, I've had to lose a few other things along the way, so it's not very surprising if there's another "new" annoyance in there now.

yes you can and even allergic. A friend of mine became allergic to nuts and uncooked (but not cooked ) fruit in her 40s.

Thumbwitch I don't combine carbs. and protein at the same meal ie. The Hay diet and that removes all the horrible acid problems especially eating fruit on an empty stomach or only with seeds and nuts.
