I love all these whacky avenues people take when eating just plants is a very low foot print option available to almost everyone. We don’t need to eat crickets, we don’t need to eat algae, we don’t need bioreactors for growing meat. I think the main reason we don’t hear more about just how goddamn efficient a bowl of lentils and rice is, or oatmeal, is because it’s not sexy. You just can’t make a start up on beans an…

Being vegetarian is extremely unhealthy, drives the obesity epidemic, and is far more likely to cause individuals to become depressed. Good luck getting heme iron, carnitine, carnosine, taurine, creatine, B12, Vit D, and DHA in a meat free diet.

> I think the main reason we don’t hear more about just how goddamn efficient a bowl of lentils and rice is, or oatmeal, is because it’s not sexy. No, we don't hear about it more because it's not healthful. If it were, the human digestive system would be like that of cattle, but it's not. You can feed everyone carby, fibrous meals, but that's not optimal and not even necessarily better for the environment. The reason…

Sorry, but lentils are pretty much the closest thing to a single food that meets all of a human's nutritional needs in existence. If you pair lentils with a small amount of spinach and eggs that gets you there.

Your comments about what "people" were designed to eat also sounds pretty ignorant, since we're not genetically homogenous for starters. Most humans of European descent have evolved for seasonal carbohydrate consumption, which is why they make you fat in excess (good luck surviving a hard winter lean). The only people who really shouldn't be eating carbs are indigenous people from very cold areas with a primarily marine diet. There are pockets of indigenous Americans from desert regions who don't do fantastically with carbs either, but those people mostly have issues with a caloric surplus in general.

Seaweed is a better food (and habitat) for fish than humans. We should create artificial reefs and forests to feed fish, then sustainably harvest fish from those manmade "farms".

>because beans and rice are healthy I disagree. A high carb diet make me fat. A high protein diets does not. There is no vegan way for me to eat my daily protein target without eating far too many carbs along with it. (edit: I should have stated that there is no way beyond eating highly processed foods)

I feel the opposite, as soon as I start supplementing with whey protein or adding meat I put on muscle and weight, but with mostly beans/rice/lentil diet I have consistent energy and stay light.

I think the "protein" obsession we have currently (even my milk carton brags about protein content) might be dialed back in the near future. It came from the weight lifting community, and lifting weights is one of the least healthy and functional ways to stay in shape. Hopefully we view hiking and doing physical activities as being "in shape" soon versus going to a gym to do a bunch of isolated movements with weight.

A quick Google search reveals that beans are not a complete , since they lack several essential amino acids. Edit: correction, it appears that soybeans are the exception. But when one thinks of having a serving of "beans and rice", soybeans are unlikely to be the bean served.

beans != beans + rice; See also: https://news.ycombinator.com/item?id=33564109

My mistake, I had blindly dismissed rice since it is commonly known to be a nutrient poor food. But several sources confirm the parent post and your comment are correct*. It's also too often repeated that a vegetable based diets will be lacking essential amino acids which seems like a gross falsehood now if you can get there with two wildly available plants that make up a common low-cost meal. I am baffled by the disconnect.

*I don't cite the source since I am unsure if there are caveats or if the claim is controversial.

you eat so many bugs all the time, ground up in food. this dismissive old crank attitude is ignoring simple truth. also a lot of the world happily eats bugs as a delicacy. they’re not whacky, you’re being quick to frame something you don’t know much about as dismissible.

Beans + rice is easily the most common meal on the planet, as the cheapest complete protein source around. We live in a bubble, never mind saving the planet

> complete protein source On the “complete protein” concept, by a famous popularizer of plant-based protein-combining[0] —— There is no need to combine foods at individual meals. “In 1971 I stressed protein complementarity because I assumed that the only way to get enough protein ... was to create a protein as usable by the body as animal protein. In combating the myth that meat is the only way to get high-quality pr…

Animal protein still seems to be of higher quality. Even among rich vegans in first would countries, the children comparatively less developed compared to their peers.

All of the people who are saying they'd never eat it and will stick with their beef/chicken/pork are the same kind that said hell no to EVs. They'll die out and the world will adapt to a changing food economy just as we did with the changing fuel economy.
