Boiled and steamed low-AGE diet,
does it really help with Improvement in circulating AGEs and cardiovascular risk markers?
research showsFood AGE values, some estimated from a database, were lower when the same ingredients were mainly boiled and steamed. In a 20-person, two-week-per-period pilot crossover trial, serum CML and MG-H1 measured by mass spectrometry also fell. Mean body weight fell by 1.8 kg over the study, lipid findings depended on sequence, and cardiovascular disease or long-term health was not measured.
ads claimClaims that boiling or steaming lowers glycotoxins and therefore prevents vascular aging merge a composition change with disease prevention. Only short-term biomarker changes were measured.
Useful facts when choosing a product
- The low-AGE diet mainly boiled and steamed the same ingredients that were grilled or baked in the high-AGE diet.
- Food CML, partly estimated from database values, was about twofold lower (P=0.0001), whereas serum CML and MG-H1 were measured by mass spectrometry.
- Verdict 1964 is C with 54 points and concerns microwaved purple potatoes and blood pressure; this verdict concerns moist versus dry cooking across foods and AGE and lipid markers.

What the research actually shows
Twenty healthy adults entered an open-label randomized crossover pilot comparing two weeks each of low- and high-AGE preparation of the same ingredients. Some food CML values were estimated from a database or substituted from similar ingredients and methods, and were about half as high during the low-AGE period. Serum CML and MG-H1 measured by mass spectrometry were also lower, alongside a mean 1.8-kg weight loss over the study. Serum comparisons mainly used simple paired tests, while weight was a fixed effect only in the proteomics analysis. The registry listed 11 primary outcomes: fecal calprotectin, short-chain fatty acids, microbial composition, two permeability measures, two systemic-inflammation measures, cardiometabolic markers, lipids, weight, and handgrip strength. The trial began on 2022-02-01 and ended on 2022-07-30, but its first registry submission was 2024-07-31, making registration retrospective.
Why this is classified as C (50)
This was a 20-person, two-week-per-period biomarker pilot. It was small and short, and weight and dietary-composition changes moved alongside cooking. No validated clinical threshold or adjusted estimate permits the mixed marker results to be reduced to one clinically interpretable effect size.
Counterpoint. A fall in circulating AGEs is a biological signal, not evidence of fewer myocardial infarctions or strokes. A longer isocaloric feeding trial is needed.

| Endpoint | S | Surrogate marker - laboratory or imaging measures |

Stored derived and displayed grades match; this is not a current recalculation or validity check (C).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Boiling and steaming reduce AGE exposure from the same ingredients | C | The estimated CML contrast was measured in the study diets but can vary with cooking conditions. |
| Low-AGE cooking prevents cardiovascular disease | ? | The trial did not measure clinical cardiovascular events. |
