Component
Coronary heart disease
Coronary heart disease. Species, exposure and limitations are retained in each linked claim.
4 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What acts on it
Carriers of the ADH1B rs1229984 A-allele consumed 17.2% fewer units per week, had lower systolic blood pressure, interleukin-6, waist circumference and body mass index, and had lower odds of coronary heart disease (odds ratio 0.90), with the protective association the same across all categories of alcohol consumption.

A median dose of 3.5 grams per day of oat beta-glucan significantly lowered LDL-cholesterol by -0.19 with 95% CI -0.23 to -0.14 mmol/l, non-HDL-cholesterol by -0.20 with 95% CI -0.26 to -0.15 mmol/l and apoB by -0.03 with 95% CI -0.05 to -0.02 g/l compared with control interventions, and there was evidence for considerable unexplained heterogeneity in the analysis of LDL-cholesterol with I-squared of 79% and non-HDL-cholesterol with I-squared of 99%.

Complete structured claim and evidenceThe applicant identified a total of 22 references which included three meta-analyses and 19 randomised controlled trials as being pertinent to the health claim, in weighing the evidence the Panel took into account that most of the trials investigating the effects of oat beta-glucan at doses of at least 3 grams per day have shown a statistically significant decrease in LDL-cholesterol concentrations and that there was strong evidence supporting the biological plausibility of the effect, and the Panel concludes that a cause and effect relationship has been established between the consumption of oat beta-glucan and lowering of blood LDL-cholesterol concentrations, considering that in order to bear the claim foods should provide at least 3 grams of oat beta-glucan per day.
