Become aware of what you put into your body

Read nutrition labels.
Before you buy something, read the label. If you see a long list of unknown and strange ingredients, leave it on the shelf.

Master the “ingredients hide-and-seek game.”
To win this game, simply don't buy any processed food in a package with a long list of ingredients with strange names. Instead, buy whole-plant foods like vegetables, fruit, nuts, whole grains, and legumes. Examples include cabbage, tomato, bananas, oranges, oats, lentils, been, peas, walnuts, etc.
