Eat less meat but.......

But, BradfordLass, lentils are worse than horrible!!

I went to a vegetarian restaurant with my DD last week and there was nothing on the menu I could eat - I have a garlic intolerance. They made me a special wrap with veggie cheese, lettuce and tomato. Garlic seems to be an essential part of a vegetarian diet. That’s my excuse for staying omnivore! (Although I don’t eat much meat and am very particular where it comes from)

I understand it is quite hard to eat a balanced vegan diet so you do need to do quite a lot of research before going totally vegan.

Can I suggest that you revert to your original diet then gradually bit by bit introduce more vegetables. Very slowly. Also your gut bacteria need to upgrade themselves to deal with these changes too.

Try a probiotic like Bio-Kult available from Boots and other good chemists and cheap. Start off with the maximum daily. dose.

You can have a food intolerance to absolutely anything. I have many of them due to a multitude of health and pancreas problems!

But for some people as they get older they need digestive enzymes at the best of times, and definitely for a drastic change of diet like yours. Beano would be good, and also introducing beans and pulses (or any change of diet) slowly, as mentioned above, would be good.

There are many alternatives, delicious too, to beans.

Try the range of lentil - lentil sooup has to be the quickest ever soup to make. A handful of split, red letils, a little bit of spice and a couple of cups of stock.
Ready in less than 5 mins.

If you are determined to eat the beans, try adding winter savoury (herb) to the dish, it certainly helps with windy tummies.

And if you are over 50, then you should ideally be taking acidophilus bifidus capsules regularly to help your whole digestive tract to stay healthy.

Our guts slow down as we get older and don't work as well, need the good bacteria to be renewed. It will also help you digest those beans better.

I agree wth IAM64, introduce pulses and other plant based food substitutes slowly.

You could try these.

Beano tablets

Eglantine - it may be that you're introducing fairly large portions of beaans/humous etc that your body hasn't had chance to adjust to.
I'm not a food expert at all but I expect your body will adjust, just go a bit more slowly and I'm sure all will be well. I was away for three weeks this summer, didn't eat any meat at all, ate lots of spicy, veg/pulse based dishes. No digestive probs at all until I came home to a more usual western diet.
