Meat is not necessary. Plenty of lifelong vegans healthy enough to disagree on that. However it's pretty well documented that a diet with an amount of meat is healthier than straight veganism, though in much lower amounts than we generally consume. Animal husbandry is also likely an important part of sustainable large scale agriculture, but again not in a way that remotely resembles modern mass scale cattle production.
These are, of course, micro optimisations versus the importance of good genes and there’s a lot of uncertainty regarding these studies... but the notion that meat is important for good health is absolutely false.
Compared to veganism, not lacto-ovo vegetarianism. It's of course a difficult issue due to conflating factors, i.e. to speculate wildly the mental heath effects of being vegan in a world that hates them.
Your article puts pescatarians at the top in longevity but has vegans above lacto-ovo vegetarians. Maybe dairy is an issue and just ovo vegetarian is the answer.
My speculation: diets high in vegetables and low in meat reduce inflammation and improve gut bacteria (this is true). So I’m guessing since there are connections between mental health and both perhaps the diet itself is beneficial to mental health?
Fact: And as for hated... it’s so mainstream in London now that if you’re a supermarket or restaurant without vegan options you’re going to lose a lot of business. Many explicitly advertise selling vegan stuff. I think it’s very accepted here now and I expect that to be a trend everywhere.
My speculation: it seems that the key component in fish is the oil and for that there’s algae alternatives. So perhaps a vegan diet with fish oil is the ideal one.
Single data point and context; I’m 100% vegetarian, 99% vegan, eat algae oil and am very healthy. Do with that info as you please ;)
Some cultures eschew dairy almost entirely. Most of the world is lactose "intolerant" actually. Not sure why it would be considered an important part of ones diet.
Dairy is a key part of the diet of hundreds of millions of vegetarians. It's undeniably important to the diet of a large portion of India's population, for example.
A different sort of vegetarian diet might work without any dairy (I'm pretty sure this describes some traditional Buddhist food). Not everyone uses the same stuff.
And Inuits have tradirionally had an essentially carnivorous diet. Diets have adapted to niches from long ago - even though lactose tolerance is technically the mutation instead of lactose intolerance.
A kind of off topic question: in that video you can see that not only is Katie breathing every 2 strokes, but her stroke timing is "staggered" - 2 strokes, pause, 2 strokes, pause - like a heartbeat. I think Phelps does the same thing. Is this just a style thing or is it actually faster?
This is called galloping (might have other names too). In general, freestyle has two extremes: shoulder driven and hip-driven. Shoulder driven freestyle is faster but less efficient, and hip-driven is slower but more efficient. Galloping alternates between hip- and shoulder-driven strokes, which is why it seems uneven. This also allows the swimmer to take advantage of the motion of breathing to build more momentum. I don't know if it is truly faster or not though.
Thanks! They definitely didn't teach us to do it that way when I was a kid, but that was back in the dark ages. I'll have to try it to see if it works for me.
I dont think this is settled -- I've seen world class swimmers do it both ways. Personally I find taking a long stroke after each breath more effective.
The popularity of lobster is generally attributed to it being canned and served on the railroads (thinking that they could get away with serving cheap meat to customers in the midwest unfamiliar with it) and then people developing a taste for it.
I only ask because you're saying this on a website. A website focused on funding technology startups. Hosted on the internet. Build by darpa grants. Like, this doesn't seem like your sort of place if you're serious about thinking technology is evil.
