Oranges v supplements.

Is an orange just a source of vitamin C say, as per a supplement, or is there more going on?

Prof Tory L Parker and team established the components of a standard orange and the amounts of each found in whole fruit. The team then systematically checked each combination of these compound to see whether the effects were the same as whole orange, more beneficial or less beneficial.

Whenever we eat carbs and fat, we release free radicals that increase the risk of hardened arteries and heart disease. Eating fruit as a dessert protects us from this, as these contain anti-oxidants that mop up the free radicals for a few hours.

The question is – which combination of anti-oxidants works best? Can you just throw everything together and it works?

The anti-oxidants (individual phenolythic compound) in a navel orange are quercetin, hesperidin, luteolin, myricetin, p-coumaric acid, naringenin and chlorogenic acid.

By systematically checking the Oxygen Radical Absorbance Capacity (ORAC) for every possible mix, it was found that some had very high benefit, but one component actually reduced this. This means that while whole orange is good, it isn’t at the optimum.

The team found that hesperidin and naringenin were synergistic, giving an effective that is stronger than merely additive.

The university where the research was conducted has applied for patents on the results, in navel oranges and for similar work done on blueberries and strawberries. No doubt supplements with these mixes will be forthcoming.

In the meantime, remember you can get most of the benefits by ditching the sweet after a meal and eating an orange instead.
