26. Fast foods and its preservatives and MSG
There is no surprise here: Fast food is a definite no-go when you hit your 40s. When you eat fast food, you tend to want more of it, so it’s smart to just avoid it all together. Fast food has also been linked to Type 2 diabetes and insulin resistance. A recent study of 3,000 participants showed that the individuals who ate fast food more than twice a week were twice as likely to develop insulin resistance, and subsequently, diabetes.

We haven’t even touched on the weight issues revolving around fast food yet! The poison lies in the name, “fast.” Most of these foods come pre-made and have gone through some preservative process. Then there is the sugar content: There is too much of it. Lastly, many fast food companies rely on MSG to enhance their food’s flavor. In the end, you end up craving more and overeat.
