Food additives are substances added to products to preserve flavor, enhance taste, or improve appearance. While many are safe, some have been linked to health concerns ranging from allergic reactions to long-term metabolic effects.
Common Additives to Watch

- Artificial sweeteners (aspartame, sucralose) — May affect gut bacteria and appetite regulation.
- Sodium nitrite and nitrate — Used in processed meats; can form harmful compounds when cooked at high temperatures.
- Trans fats (partially hydrogenated oils) — Raise bad cholesterol and increase heart disease risk.
- Monosodium glutamate (MSG) — Can cause headaches and sensitivity in some people.
- Artificial colors (Red 40, Yellow 5, Blue 1) — Associated with hyperactivity in children.
- BHA and BHT — Synthetic antioxidants used as preservatives; potential endocrine disruptors.
- Carrageenan — Thickener in dairy alternatives; may cause digestive inflammation.
- Potassium bromate — Flour improver banned in many countries but still used elsewhere.
- Phosphates — Found in processed cheese and meats; linked to kidney and cardiovascular issues.
