I sometimes use Siri to set timers while cooking. Unfortunately, adding items to the shopping list doesn't work well enough, Classic Siri is not smart enough to place them in the food section.

It's because the ideal person is put in a disadvantage against the lazy person.

Someone who actually wants to learn can use it to learn, or to improve quality, or do other beneficial things. Although it's certainly not infallible and the output can't just be trusted.

People are lazy though, and in a lot of places you'll find that for every 1 person who cares about their craft and wants to learn, there are 10 that just want to get the work done with minimal effort. So now it looks like the lazy ones are more productive than the conscientious people.

But these examples have different glycemic indexes, which the study matched for.

Edit: There was also the Euro Alliance of Payment Schemes

Electricity consumption is not constant, just like generation isn't constant with some sources. You can certainly replace a number of peaker plants, e.g. gas turbines, with storage and reduce costs by a lot.

As for panel production, you don’t really have to make them locally. Panels are sold with minimal margins (although your tariffs could allow for some local margins). You can make more money off installation and related services.

That being said, people don’t eat macronutrients, they eat foods. With equal caloric intake, a vegan diet is going to be higher in fiber and lower in fat and protein than a diet that includes meat. That’s probably part of why it’s healthy, but the reason for doing this study is to understand the mechanisms in more detail, rather than just claiming that one is better than the other.

When you say they should have supplemented fiber, you’re also implying they should have had less meat. According to the linked paper from this year, the meat-rich diet included at least 150g of meat per day, which is just a bit more than a chicken breast or a single burger patty. Probably in line with what many expect from a balanced meal.
