Including protein powder as a cooking ingredient does not do much for improving the taste of food (though the food definitely feels more satiating), but it ensures that it is healthy enough.

Even if I liked meat, I never felt any kind of addiction to it. There are many years since the last time when I ate meat and I feel no need to eat again, as long as I have a lot of other options for food that is tasty and healthy.

For several years I have not used any animal protein sources, but this forced too inconvenient constraints on what I could eat, so eventually I gave up and now I use in cooking some whey or milk protein concentrate powder, whenever it is necessary to increase the protein content. This has provided much more freedom in menu choice.

So for me, if instead of having to buy protein extracted from whey or milk (which costs about the same as chicken meat, i.e. many times cheaper than protein concentrates extracted from plants, which must use much more complicated processes than the filtration of whey or milk) there would be the option of buying similar protein from a fungal culture, that would be enough to cover all my needs.

From other comments that I have seen about the fake meat products, I am pretty sure that there are many others like me, who do not care whether they eat meat or not, as long as they eat some good food.

Eliminating beef, fowl, and fish leaves a universe of foods including all fungi, fruits and vegetables, grains, nuts, and legumes. It also includes all spices and herbs.
