Thank you for yor very helpful comments. I have been mostly vegetarian since 1972 and mostly vegan since 2002. the only exceptions made are when travel requires flexibility. for instance, as a guest in a house in India, I take a small amount of curd (yoghurt) as it is offered. My wife, on the other hand, would choose to starve rather than break out of the vegan mold!
I will offer the following detail on our dietary habits, and perhaps you or others have some suggestions on the following:
Our energy level is quite good. We enjoy the outdoors and also doing physical work around our place in Vermont. We also love cooking and eating together, and we do follow your guidelines to take warm food in the cooler weather, and we save our eating of raw vegetables seasonal consumption, straight from the garden, bush or tree. We do eat one or two pieces of fruit daily in the winter.
You spoke of variety, which we try to follow. We eat only whole grains cycling between brown rice, millet, quinoa, amaranth, teff and occasionally I make flatbreads from whole wheat, spelt or rye flower. With the whole grains, we always soak them before cooking. Breakfast is oats mixed with whatever leftover grain from the night before, with ground up sesame, flax seeds and whole raw sunflower seeds.
Similarly, we cycle through a wide variety of root and green vegetables. Daikon radish, turnip rutabega etc. for roots and kale, collards, and mustard greens (daily) for green leafies.
Leumes and beans are a similar story. All pre-soaked, of course. Pintos, black beans, split peas, mung beans, adzuki beans, etc. , French lentils, Mysore lentils and more.
We try to get some fat and other nutrients by eating nuts. i'm not sure how we are faring on this one. I love them so try to limit my consumption to maybe a handful a day, but sometimes go a bit over on that. I haven't noticed any negative effects, and my cholesterol and blood pressure are in the normal/low range so I don't think I'm cloging up my arteries, but I have heard it is good to be careful with nuts. We eat them raw, unsalted.
The only noticable side efeect from all this is that I tend to pass a lot of gas. It isn't uncomfortable or anything, but i wonder if it is a sign of overdoing something or wrong combinations.
I appreciate you or any others taking the time to read the above and gove any pointers or advice. Also feel free to ask for clarification.
