My lovely wife is nearly 17 years younger than I am.
At my age that is a significant difference. Over the years we have been together her diet has made a large accommodation, and is still slowly changing. She has gained bodyfat, true, but is still far slimmer than the average women her age. Perhaps the gain is due to her liking of pasta and rice. Nowadays she only very seldom indulges. She eats squash and a few other high carb veggies sometimes. She also likes pawpaws (papaya) and other fattening fruits. She always eats some sort of salad with her meals. She likes eggs and eats more cheese than I do. She makes wicked egg salad and chicken salad, but puts celery in both, which I have to pick out- (no carbs, but I think it tastes awful). She is like me in her love of exercise and that may help her health.
I am not in the least interested in the food she likes, so I don't pay any attention to it in the fridge, even after smoking a doobie.
I only seldom say anything any more about what she eats unless I think it extremely carby. Fortunately she has a very good HRT formula which is based on the human estradiol rather than that dangerous pregnant mare's piss-derived one used in that interrupted study. The many estrogens found in other animals like horses, are not found in humans and like any alien hormone either have the wrong actions or have other added actions you may not want. Carbs/insulin is very artery damaging, but the normal female estrogen level seems to give excellent protection, why I have no idea, but I do know that as we evolved women simply never lived long enough to reach menopause.
Other animals can breed as long as they live, and once we could too- but now we live far longer than our bodies have evolved to handle in many ways. Of course estrogen also maintains the sex drive and vaginal lubricity as well as bone density. Even males need enough estrogen (which can be made from testosterone) to build and maintain bone density. I do not know how she will fare in the years to come... I would be far more comfortable if she ate like I do, but I am a realist on diet. She admits my diet is very good and is perhaps the best, but is strongly accustomed to her ways. I am always quite surprised when anyone can manage on it for long enough to make it their own.
Food for humanity: Fewer people would mean room for more food-animals a balanced ocean, land in grasses and trees, water which is abundant and clean. Clean air.
Yes, the truth about diet will out if only you can manage to center yourself and quiet down all that socially induced 'noise'.
A little bit of dissembling:
We are the eaters of cows, and we must NOT eat their food. That is the way of Gaia, the Conscious Planet who has placed us at the very pinnacle of the food-chain-eco-pyramid which is very small at the top. If we had remained where we belonged, rather than stepping down a level or two, not only would we live well and enjoy good health, but there would only be as many of us as the world can support. There would be no crowded struggling cities filled with the desperately poor, no pollution and no destruction of the ecosystem. The planet cannot carry us at the present population level, it is rapidly failing. The worst, most disastrous move we have made, worse even than the wide spread havoc caused by our uptake of the fundamental superstitious religions, is the consumption of vegetation. It has allowed us to infest the planet like ten thousand fleas on a Chihuahua. At least that is how I view it. 5 million, or up to 10 million, maybe- but no more is a good human population level, NOT six thousand million.
