I totally agree that cooking can take significantly longer then "a few minutes", but there is plenty to be had in terms of a quick meal. For me the most worrying part is when the creator of the supplement is stated to have no time for meal preparation due to his work. It is ok to just eat a quick sandwich or a joghurt/fruit combo every once in a while, but if you cant spend some time on proper meals your life is going in a very wrong direction.

What about shopping for groceries? Salad and some vegetables lose taste and vitamin after a few days. Even if keep it in the fridge. If you want to eat fresh and healthy food you will have to go shopping more often.

Food spoilage can be an issue too. I can't imagine how how much food has been thrown into the garbage because it looked untasty.

This is all just part of food education on how to properly store your products. Some people living in remote areas are prefectly fine living on a diet of fresh produce going shopping every other month, while some buy their food every day. It is not really a limiting factor, more of an excuse.

Either pick up a few things while you're out and about or get things delivered.
