3. High Fructose Corn Syrup
This processed sugar is produced from GMO cornstarch, which undergoes an enzymatic process to chemically convert half its glucose molecules into fructose, which is sweeter (6).
This syrup is directly linked to obesity and non-alcoholic liver disease.
4. Corn Syrup
As with any processed sugar, high consumption of corn syrup can lead to obesity and insulin resistance.
5. Natural Flavor
The FDA qualifies natural flavouring as “the essential oil, oleoresin, essence or extractive, protein hydrolysate, distillate, or any product of roasting, heating or enzymolysis, which contains the flavoring constituents derived from a spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, seafood, poultry, eggs, dairy products, or fermentation products thereof, whose significant function in food is flavoring rather than nutritional” (8).
This means that anything naturally occurring, even sugar, can be considered natural flavor.
So you may have noticed that Heinz tends to use a lot of corn in their ketchup, but there’s still more:
Citric acid, often derived from corn, is used to preserve freshness and prevent Clostridium botulinum contamination. This harmful bacteria can cause neurological damage, so processed tomatoes almost always contain extra citric acid.
Spices used in commercial food processing often contain calcium silicate, a corn-derivative, as an anti-caking agent.
Salt, also known as table salt, is iodized, meaning that it likely contains dextrose, a corn-derived sugar. Dextrose is used to stabilize the potassium iodide added to the salt (11).
Heinz has since launched a certified organic ketchup, but registered dietitian Stefanie Senior warns that even healthy ketchup is so high in sugar and salt that you should limit your serving size to one tablespoon a day (12,13).
