I was explaining this to my daughter in quite simplified terms the other day- we evolved to taste sugar and enjoy it because finding a sweet edible plant meant we had a source of energy to help us hunt that day. Pretty useful if you're a hunter-gatherer.
So we seek out sugar. Now we can get it whenever we want it, in much more massive quantities than we are supposed to be processing. Most of us are addicted. I'm not an exception.
I've never done that, but I've made cheese out of yogurt by putting it in cheesecloth and letting all the liquid drain out of it over a day or so. Mix it with some chives and it's amazing on crackers.
Making your own everything isn't feasible for most people, but if you are at home more than not it's doable. My 4 siblings and I grew up with a mother that insisted that we make bread, pasta, and everything else from scratch. Thankfully we had an automatic bread maker, and waking up to a fresh baked ¼ or ½ loaf of bread, daily, is amazing. The pasta maker wasn't as fun, but it wasn't the work that we went through at Grandma's house, with her manual pasta maker.
We all are relatively tall and skinny, though we all have some form of a "beer belly, love handles, etc." I can tell you from experience that the other kids knew we were getting "the good stuff," even though it was all healthy food. Apparently this saved them a lot of money when all three of us boys joined the swim team, and they had absolutely ravenous locusts swimmers in the house for a total of a decade.
It also led me to being able to get jobs as a line cook, and eventually a chef, when I needed a second or third job.
Edit: sorry, my point was that this is an excellent way to limit the added artificial sugars in all your food, and it will help create healthy eating habits that stick with your kids, even if they have to eat cheap junk for a few years.
