Everyone should be educated on the subject of nutrition. It is the most fundamental knowledge. You are what you eat, your body is literally reconstituted nutrients from the soil, but your mind and spirit are made of other things. There shouldn’t be so many overweight and sick people in a country where food scarcity is hardly an issue to most.
Most people bring about their own destruction. Benjamin Franklin said, ‘nine in ten men are suicides.’ If you really valued your own life, you’d eat higher quality food and not mess around with the cheap stuff, like too much protein or too much sugar, dairy, and gluten.
If people were smarter, they’d dedicate some time every day to the production of their own food, and also some time to study nutrition. Nutrition is all about finding out what is best for yourself. Help yourself.
Of course, exercise is important too. But diet is more important than exercise in the fitness equation. If you really want to look and feel good, you have to exercise, but if you just want to be normal bodyweight and live nutrition is the first subject to learn.
I know people have day jobs, so eating home cooked food is not always an option. But if people had more knowledge, they could make better food choices at restaurants and whatever. It seems the West has exchanged one set of diseases for another. Although more people are living to adulthood than in previous centuries, and infectious disease isn’t such a big threat in the developed world, people aren’t living the quality of life that is optimal.
Just educate yourself, and all things will fall into place.
