It's not true that by weight chicken breast has higher concentration of protein than beans. 100g of raw beans, or 100g of raw lentils, has more grams of protein than a chicken breast. 100g of raw soybeans has more grams of protein than same amount of beef. Of course, "raw" is the catch word, because when cooked, beans/lentils fill with water and then you might claim that concentration has been lowered but the amount…

Protein:Fat+Carb ratio is what matters when talking about protein concentration.

I applaud the desire to help humanity eat healthier and saner amounts of meat, but... I remain unconvinced that creating relatively resource-intensive fake meats is better than using highly efficient non-animal meat[0]. Most people won't eat either one unless they have no choice, but if it comes to tha…

I think many people would rather burn the planet down than eat fly larvae.

You wouldn’t advertise it as fly larvae.

People in the West already enthusiastically eat many things that would make them seriously unhappy if they had to think about the origins.

It’s even simpler than that. There are some people who simply don’t function as well when they don’t eat meat. “But I’m vegan and I do just fine, in fact it I feel better then when I was eating meat”. I don’t doubt you, but I also don’t doubt the ex-vegans who tried and tried, but just felt awful and tired until they reintroduced meat. Different people have different metabolisms, and some people just can’t properly d…

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6893534/ This review debunks the "bioavailability" and "quality" claims quite easily.

I think you misunderstood the protein concentration concerns. People are concerned about the ratio of calories from protein to calories from other macronutrients. In the case of beans like edamame, the concentration of fiber becomes relevant as well.

In contrast, chicken breast is nearly entirely calories from protein and very low fiber. Replacing some chicken breast with soy makes sense, but your fiber budget would cap out quickly and that would leave no room for other fiber rich foods like fruits and leafy green vegetables.

Why does a food need to contain 90% or 100% protein? I think many people vastly overestimate how much protein they need.

I know a lot of people who have had success maintaining fitness goals on a high protein diet, including people who struggle with obesity.

I'd say that latter case especially counts as a need.

There was an explicit mention of protein quality and bioavailability. Both terms are standard and widely used. If OP meant something different by these terms, then fine. There's a minor loss of protein that is trapped in fibre for most plant foods that humans eat.

There is small amount of fiber in tofu, seitan, tempeh or other soy derivatives.

The "protein concentration" was mentioned together with iron, as if it is a problem of deficiency, not in the context of obsessive compulsive dieting by tweaking your macros to achieve the best results.

I am not sure the fiber budget you mention is a reality. There is no threshold where your body will stop behaving if you consume too much fiber.

My diet is roughly 40% protein, 35% fat, 25% carbs. It’s extremely high in protein as I’m on a 20% calorie deficit, aiming for at least 1.2g protein per lb lean body weight, 35% fat preferring it to carbs and making up the remaining calories with carbs. I prefer fat over carbs as my body hangs on to carbs and doing a metabolic test was told I would be better with higher fat to carb ratio based on my stats and goal of…

I did competitive powerlifting for a while and am still an avid stength trainer. I didn't go full vegan, but my wife did, and there for a time my diet mostly aligned to hers because she was doing the shopping while I was working. Overtime I started to get a lot of minor injuries out of nowhere. I tried doing a vegetarian diet and tried my damndest to get all the nutrients without meat. But after some time I always fe…

How is an example of doing a tail activity like competitive powerlifting and the anecdote of underperforming in the activity on a vegan diet relevant?

I am pretty sure that gentlemen at the lumber yard do not have 300kg deadlift events and are not competing.

It is well known that diet has very little to do with progress for an amateur athlete. Consistency is the biggest factor in long term success. If you want to eek out the most out of your body, then you might want to optimize, but then you're already deviating to obsessive behavior.

Yeah, if you want to increase your squat by 20% short-term, you're going to have to eat more food and be obsessive about it, but if you're fine with consistent training over a span of 10-20 years, there's no reason to stress too much about diet.

When I hear people talking about diet and "optimal performance", I always wonder what the hell are they doing that they need to optimally perform. Like, what exactly is optimal performance of a sedentary programmer that maintains elasticsearch clusters? What, he feels tired sooner if he's on a vegan diet instead of something else?

As I understand it your technology is in part about providing a scaffolding that enables normal animal cells to grow. But there's a question that I genuinely think is important, but risk sounding like a troll. The qualities of a successful cancerous cell, to grow without restraint, unimpeded by the density of other cells or whether the cell is attached to a surface, will probably be even more successful in a bio-reac…

a tumor burger? doesnt sound very appetizing.

I encountered tumors in regular meat of many varieties multiple times. For some reason, pork has the biggest probability of tumors.

Some people have significant health problems if they eat to much fiber. They are literally on a low fiber diet as a medical matter.

The rest of us have lower GI problems of some sort if we go too much over the daily recommended amount. That can cause significant practical and social problems. But you are correct that we probably won't die. It could be painful in some cases, though, and that would be enough.

Wow. And I thought a komodo dragon eating a pregnant deer with fetus was the worst I have seen or imagined. Ethics aside, how do the people doing the procedure stand it without going crazy.

I'll answer your question, but it's really pretty simple. It's the same way that people have done all sorts of terrible things since the dawn of man. Someone had to slaughter the livestock. Hunters ran down animals and killed them when they became exhausted, and to be a bit more blunt, we kill each other in wars and senseless violence every day. Look no further than our current conflict in Ukraine to see what that's…

hi Anneso!! congratulations on the launch! It's truly amazing what you and the team have been able to create so far, excited to see more updates in the following months. I agree with some of the other comments around here, this might be the best launch description I've ever seen here. side note: where can we sign up to beta test?
