For example, vegetables are generally healthier than meat because they contain more nutrients, less fats e.t.c. Why do certain food categories have properties that make them healthier than others?
In: Biology
Living things have genetics that dictate what kinds of proteins and molecules are needed to make more of those living things. Some of these things are good for us humans to eat, others are not. In general, genetics aren’t concerned with what is healthy or not, they just have what are needed to survive the exception being some plants do grow fruits with the purpose to be eaten as to spread their seeds.
One interesting thing to note is that we live in a very unusual time when you look at the overall timeline of humanity. Things like fats and sweets were quite scarce when humanity was tribal and food wasn’t always plentiful. We developed taste buds that like these high-energy foods, encouraging us to stock up on energy when we could. It’s only recently that humanity reached a point where we can cultivate and manufacture these things in such abundance that we can overindulge in them, making them unhealthy.
