Eating just one red grapefruit daily for a month can help to lower LDL cholesterol by as much as 20 percent, one study in the Journal of Agricultural Food Chemistry showed. This cardioprotective effect is most likely due to compounds called limonoids and lycopene found in the pulp. Grapefruit also contains the soluble fibre pectin, which contributes to LDL lowering.
