Assuming two 570 ml bottles of standard ketchup per day, and using a typical ketchup profile, that comes out to roughly 1,140 kcal, 243 g sugar, and 10.3 g sodium per day. That is about 5.2 times the WHO sodium limit for adults, and 4.9 times the WHO free sugar benchmark for a 2,000 kcal diet.

I’d expect… After a week: water retention, increased thirst, heartburn, stomach irritation, possible nausea or diarrhea.

After a Month: noticeable weight gain, elevated blood pressure, dental damage from sugar and acidity, blood sugar instability.

After a year: risk of insulin resistance, cardiovascular risk, clear deterioration in overall diet quality and metabolic health.

But why?

You get yummies

Ketchup has more sugar than cola, so probably obesity and diabetes.

Ketchup is fermented so it’s maybe kind of good for your microbiome

Diabetes? Obesity, over time?

I make ketchup at home and if I were to use the original recipe it would include a shit load of brown sugar and molasses. Like 1/2 cup of each, and that is for maybe 1/2+ of a Heinz bottle, maybe a tad more.

For health reasons, I made my own recipe but even then, even if I wanted to, I could never be able to eat the equivalent of even half bottle in a day.

My recipe uses next to no salt, since sodium is used as a preservative. My ketchup will not last for as long as say a Heinz bottle but ketchup form the store has tons of it. So that would add to negative cardiovascular health outcomes, like increased blood pressure, just to name one.

Not much, you need to drink 3 bottles per day to get any significant effects.

Are those Usonian bottles or European ones?
