We are blessed with a vast variety of choices in our lives, from food and clothing to home, office, and personal health products. But along with all the choice comes a responsibility to make wise, informed decisions—which means we need to recognize ingredients in these items that may be harmful to our health.

Some are found in foods and beverages while others are lurking in clothing, personal care products, medications and supplements, household cleaning items, and everyday products. Some ingredients can be found in more than one category.

That said, here is our list of ingredients to avoid in 2018—and always.
