I haven't eaten meat since Jan 1 of this year as an experiment in blood panel results, body fat, and general "feel" of abandoning meats. I was already mostly dairy free (don't consume animal milks with the exception of purchased baked goods or cheeses - a few times a week at worst) for over 7 years.
If you haven't tried a shift toward a plant based diet, I would argue you have no clue. Because I didn't. Giving meat up is actually easier than things like cheese as an example.
I lost 10lbs of body fat in a month (5'11 @ 175 --> 165) and increased strength in January. I also improved all blood panel markers by a minimum of 15% (WellnessFX). But the best part is the subjective part: overall feel. I feel much better, more consistently and more often on mostly plant based. Things within my pallette have changed quickly.
Dr. Greger's "How Not to Die" has helped in some of the education and all the references to studies relating. Cooking, however is a fundamental shift from Paleo so that is one of the hardest parts you have to focus on right away. I had so many recipes I loved and became frustrated early finding alternatives. However after 2 months I'm enjoying cooking with new foods and techniques. I've picked up about a dozen new cookbooks and have learned a lot in short order.
Overall, again, I feel your statement is unfounded and I'd suggest for those interested in improving their health to try slow shifts to more plants. There's only upside and there are many studies in support of.
The final piece of it is our planet. Animals raised for meat production requires excessive energy and waste. Beyond that most of our meat supply chain is riddled with things such as E Coli (supported in many recent studies - as an example of the many: https://www.asm.org/index.php/mbiosphere/item/6219-connectin...).
TL:DR Don't miss meat after giving it up. Those who say it adds "value" without actually trying don't have basis to support their claim.
Please, speak for yourself. Some of us have enough trouble find a variety of food to eat without such restrictions. It is actually insulting to be told that radically changing my diet as an unintentional lifelong picky eater is some trivial exercise.
Furthermore it is arrogant to judge value so certainly on behalf of strangers. Put frankly, who are you to tell me what I do and don't like?
Did I ever try to tell you what you should like? Nope. Get a grip.
There's also mentions of "slow shifts" and similar, indicating that the change of your diet is not radical and sudden, but gradual and slow.
Picky eaters have a somewhat disease and should try to incorporate variety. Otherwise you risk black swans by eating practically the same thing all your life. Eating many ingredients is antifragile :D
I don't doubt his good intentions and I think he attempts to be balanced and use science to back his arguments. But he clearly starts from the position that meat is bad as I think perhaps you do. And perhaps it is. But I would prefer to see that established without prejudice.
If you have an ethical problem with eating meat then don't eat it. But I get a little tired of people proselytising as a result of becoming born again vegans.
As for curing meat. As you say meat can be dangerous to consumer due to contamination. I would rather a slightly elevated risk of cancer from moderate use of nitrate cured meats than near certain death from botulism or some other nasty. I really would like to see a safer alternative become commercially available but I don't want to be second guessing the microbial safety of my cold cuts. I rarely eat bacon but cold cured meats with salad are a relatively important part of my diet as cooking in our kitchen heats the house too much during the warmer months.
I think the big problem with meat, as with the sugar epidemic, is overconsumption. If every meat eater ate meat in moderation as part of a balanced diet there would be far less environmental impact and animal cruelty than creating a small number of vegan converts. Red meat consumption has certainly dropped in Australia though chicken has offset some of that.
At the risk of belaboring the obvious, you may buy yourself some years with virtuous living, but you are still going to die. It's worth considering whether you want to give up all your small temporal pleasures.
Did I state longevity was my goal? No. "Temporal pleasures" are subjective. And you're conflating your tastes with mine incorrectly. I stated I ate a lot of meat, and enjoyed it. I don't miss it having cut it out. That was very surprising to me and I'm simply sharing thoughts. I also suggested if you haven't tried it, how would you know? You don't. Plain and simple.
You're telling us all this without mentioning what kind of exercise regiment you're on?
Also, the results of nitrosamines happen faster than I believe you expect from what you posted. Colon and rectal cancers have been on the rise for decades.
So, I see your point, but it's an uglier problem than I think you realize and there are some easy solutions available.
