Practise explaining how antioxidants reduce free radicals and endothelial damage, linking diet or antioxidant drugs to atherosclerosis risk, and interpreting antioxidant evidence.
Several factors increase the risk of cardiovascular disease (CVD).
Dietary antioxidants may reduce the risk of CVD.
Explain how dietary antioxidants reduce the risk of CVD.
An explanation that includes the following points:
- because antioxidants reduce free radicals (1)
- free radicals cause \{cell damage /tissue damage / oxidative stress / damage to endothelial lining\} (1)
- (antioxidants) reduce \{plaque / atheroma\} formation (1)
Accept neutralise / stabilise / donate electrons
Accept antioxidants \{prevent cell damage / tissue damage / reduce oxidative stress / prevent damage to endothelial lining\}
Accept reduces \{cholesterol build up / blood clot formation / atherosclerosis\}
