Hi, Longtime vegetarian here.

Look for miso paste, it is a fermented bean or grain product from Japan that is a super food that dates at least to the samurai period, reserved for nobles only.

It makes your gut biome better able to digest vegetable protein. Broccoli has more protein than steak, fyi.

Find a liquid or sublingual B12 supplement, veggies and old's both need that.

For heart health vitamin K and melatonin.

Tahini, sesame paste is great to make sauces, and confections. We make a vegan mayo w tahini for coleslaw.

Quality olive oil, fresh ground black pepper and organic herbs all good for circulation.

One recipe, get brewer's or nutritional yeast, Bragg's not red star, and take tofu, cut thin 1/3 inch slices, dredge some yeast on both sides and saute on the stove.

Tempeh is a fermented soy product, that is lower in estrogen and can be used in recipes.

And I like vegan chicken especially eating out.

Welcome to your new health hobby.
