Reduce added sugar as an inflammation driver

Added sugar raises CRP and other inflammatory markers through multiple pathways — it is not just a calorie problem.

Why it works

Fructose (from sucrose and HFCS) is metabolized in the liver and drives de novo lipogenesis, visceral fat accumulation, and AGE (advanced glycation end-product) formation. AGEs trigger RAGE receptor activation, producing a sustained inflammatory signal. High glucose alone also activates NF-kB inflammatory signaling. These pathways are independent of calorie balance — the sugar-to-inflammation link exists even without weight gain.

How to do it

1. Eliminate sugar-sweetened beverages first — they are the highest-glycemic, most insulin-spiking, most inflammation-promoting form.
2. Reduce obvious added sugar in coffee, cereals, and sauces; you do not need to eliminate all sugar from fruit or naturally sweet whole foods.
3. Replace sweet snacks with alternatives that include protein and fat — the satiety signal will reduce craving over weeks.
4. Read labels for "added sugars" rather than "total sugars" — the added column is what the inflammation research addresses.

Evidence

Multiple controlled trials show that sugar-sweetened beverage consumption raises CRP, uric acid, and inflammatory markers; sugar reduction trials show reversal of these effects. (rct)

Stanhope et al. used very high fructose doses in controlled conditions; real-world effect sizes at typical consumption levels are more modest.

Common mistake

Switching from regular to "natural" sweeteners (honey, maple syrup, agave) without reducing total sugar intake — all are sucrose-equivalent for the inflammation and glycation pathways.
