Dietary SunGold kiwifruit intervention
2 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 it acts on
Four weeks of two SunGold kiwifruit daily increased neutrophil vitamin C content in young men initially selected for plasma vitamin C below 50 µmol/L (p=0.016).
Experimental context and source evidence

Complete structured claim and evidenceFollowing the four-week kiwifruit intervention, stimulated neutrophil chemotaxis increased about 20% in paired ex vivo assays (n=12, p=0.041); unstimulated migration did not change.
