Jiffy Corn Muffin Mix — DUMP

Munch or Dump rates Jiffy Corn Muffin Mix by Jiffy DUMP — score 17/90.

The adorable retro box hides hydrogenated lard — actual trans fats — plus BHT and a three-deep phosphate stack. It's beloved, it's under a dollar, and it's essentially cake mix with a cornbread accent. Trans fat is a hard no in 2026, nostalgia or not.

Why this verdict

• Hydrogenated lard means trans fats — an automatic DUMP that no amount of Americana can override
• BHT, a petroleum-derived preservative, keeping a 'wholesome' baking mix shelf-stable
• Three stacked phosphate salts (tricalcium phosphate, sodium acid pyrophosphate, monocalcium phosphate) — industrial leavening with cardiovascular/kidney concerns at regular intake
• Sugar is the third ingredient — this is dessert wearing a cornbread costume
• Refined wheat flour plus degerminated corn meal: the fiber and germ were milled out, then a handful of synthetic vitamins sprayed back in

Ingredients (16)

• wheat flour (moderate) — Thickening agent, not harmful but adds processing.
• Degerminated yellow corn meal (moderate) — Corn with the germ removed for shelf life, losing most of its fiber and healthy oils.
• Sugar (moderate) — Added for sweetness, can contribute to calorie content.
• Hydrogenated lard (avoid) — Hydrogenation creates trans fats — the one fat category with no safe intake level. Hard-rule disqualifier.
• BHT (caution) — Synthetic antioxidant preservative added to protect freshness; a processing-signal additive.
• Baking Soda (safe) — A basic leavening agent. Completely standard.
• Tricalcium Phosphate (safe) — Added calcium source for fortification.
• Sodium Acid Pyrophosphate (moderate) — Additive used to keep the fries from graying; a processing aid.
• Monocalcium Phosphate (moderate) — Leavening acid; adds to the total phosphate load.
• Salt (moderate) — Used in moderation, might exceed necessary amount.
• Niacin (safe) — Added B3 vitamin.
• reduced iron (safe) — Standard fortification iron.
• Thiamine Mononitrate (safe) — Vitamin B1 enrichment.
• Riboflavin (safe) — Added B2 vitamin.
• folic acid (safe) — Added folate.
• wheat starch (safe) — Vitamin C, acts as a preservative here.
