What to know about corn syrup
Corn syrup and high fructose corn syrup get talked about as one ingredient, and for anyone tracking fructose they are not. Plain corn syrup is glucose based and grades moderate for excess fructose and moderate for FODMAPs, while HFCS grades high on both plus fermentation. That does not make corn syrup a health food: it grades pro inflammatory and a poor fit for DASH and Mediterranean eating. It is clean on gluten, histamine, tyramine, sulfites and salicylates.
Watch for
- Moderate rather than high on excess fructose.Corn syrup is corn starch hydrolysed into glucose, and glucose actively helps the small intestine carry fructose across, which is why it sits well below high fructose corn syrup on the fructose malabsorption scale
- Still a moderate FODMAP by dose, and the dose is the point.Corn syrup shows up in fizzy drinks, sauces, sweets, cereal bars and baked goods, so the total across a day is what provokes symptoms rather than one spoonful
- Graded pro inflammatory and poor for both DASH and Mediterranean patterns.This is a refined sweetener with no fibre and no micronutrients, so the diet fit grades are about what it displaces
- Read the ingredient list rather than the front of pack.Many products list corn syrup and high fructose corn syrup together, and it is the HFCS that carries the high fructose, high FODMAP and poor fermentation grades
