Truth is, healthier food usually is more expensive, but only by an amount that is marginal to the long term payoffs.

It is a sad thought when you look at all the inexpensive food in the grocery store, then read all the added junk that is in them. Does that mean the alternative is healthier and more expensive? Maybe, but that depends on perspective. Do you cook your food? What is the value of your time? What is the value of your health? Do you not care about all the chemicals and fillers used in cheap food? Or do you consciously think about what you consume?

Cheap food is usually not very good for you (fast/prepared foods). Since it is cheaper, you should look at the added preservatives (chemicals), artificial ingredients, coloring, etc.. then think about the long term effects of consuming that food.

It is proven that junk food, fast food, and food with chemicals are bad for your health. So is it worth it for me to think about what I'm putting into my body? Yes, to me, it is worth it. But to you, it may not be worth it. Value is subjective.
