A simple guide to phosphates, nitrites, and trans fats — what they do, where they hide, and smarter swaps.
Ultra-processed foods sneak into busy lives — and that’s okay in small amounts. The issue is when three specific additives show up often: phosphates, nitrites, and trans fats. Research links them to heart disease, cancer risk, and lower energy — here’s what to know and easy ways to avoid them.
Where they show up: cola drinks (phosphoric acid), processed cheeses, deli meats, instant foods.
Added phosphates are absorbed quickly and can damage blood vessels and make arteries stiffer[1], increasing heart risk even in otherwise healthy people. High intake has also been linked with lower physical activity and more sedentary behavior[2].
Quick fix: scan labels for “phosphate” or “phosphoric acid,” choose fresh foods more often, and swap soda for water or tea.
Where they show up: bacon, ham, salami, hot dogs, some cured cheeses (look for sodium nitrite / nitrite salt).
In the stomach, nitrites can form nitrosamines — compounds linked to colon cancer and heart disease[3]. The WHO’s IARC classifies processed meats as Group 1 carcinogens (sufficient evidence they cause cancer in humans)[4].
Quick fix: choose “no nitrites/nitrates added” options or fresh meats; keep processed meats as an occasional treat and load up on vegetables for protective antioxidants.
Where they show up: older-style margarines, shortening, some pastries/fried foods, certain non-dairy creamers (watch for “partially hydrogenated oil”).
Trans fats raise LDL and lower HDL, driving artery clogging and heart attacks[6]. The WHO estimates they cause up to 500,000 premature deaths yearly from heart disease worldwide[5]. Many regions have banned them, but small amounts can still slip in via labeling loopholes.
Quick fix: avoid anything listing “partially hydrogenated oil.” Use olive oil or small amounts of butter instead of margarine and check labels even when products claim “0g trans fat.”
