This Guardian article is one of the best articles I have come across that showcases how broken the US food industry is. I have read several articles on this topic in the past; however, I love how this one summarizes the monopoly of the food industry so holistically.
Good nutrition is one of the most important things that we need to focus on to maximize our potential. We need good fuel for our bodies to perform and to think clearly. And good nutrition doesn't always mean eating the right ingredients; good nutrition means knowing that your ingredients/ food categories are nutritious. What do I mean by this? For example, a piece of a steak from a cow that is fed by corn and growth hormones has probably very different nutritional benefit for you than a piece of a steak that is from a cow that can roam freely on green pastures in a regenerative type of way of farming, and that is then killed "humanly" instead of in a slaughterhouse. Here is a great podcast I recommend listening to on this topic.
The same goes for fruit and vegetable. All broccoli and apples are not the same. This one especially concerns me as the typical answer that most average humans and even doctors provide is: "Just eat more fruits, veggies, and whole grain, and you will be fine." I often wonder how nutritious our veggies and fruits are, given that our soil's quality to grow nutritious food is depleting. You can watch more about this in this documentary I previously wrote about.
I am a fan of eating clean food. I am a fan of knowing what I put in my body and ideally knowing where my food comes from. Mainly, because I have done many food/ diet experiments myself, and I can feel the difference in my energy levels when I do and don't eat clean.
