Orange juice and juices from other citrus fruits could be much healthier than previously thought as researchers found that these are ten times richer in antioxidant content than what current methods estimate.

High content of antioxidants in one’s diet help reduce harmful free radicals in our body.

“The antioxidant activity is, on average, ten times higher than that which everyone thought up until now,” said Jose Angel Rufian Henares, professor at the University of Granada in Spain.

The new technique to measure antioxidant content called ‘global antioxidant response’ (GAR) shows that this property has been undervalued in other food as well.

The results suggest that tables on the antioxidant capacities of food products that dieticians and health authorities use must be revised.

The method includes assessments of various physical and chemical parameters, such as colour, fluorescence and the relationship between the concentrations analysed and compounds indicators such as furfural.

Upon applying the technique to commercial and natural orange, mandarin, lemon and grapefruit juices, it has been proved that their values greatly increase.

With the help of this method, scientists have also created a mathematical model in order to classify juices according to their natural and storage conditions, which ensures that the correct raw materials and sterilisation and pasteurisation processes are used.

Antioxidant Supplements May not Improve Sperm Quality: Study

Further, the natural conception rate during the initial three month was 10.5 per cent in the antioxidant group and a little more than nine per cent in the placebo group

Scientists have found that consuming antioxidant supplement daily for three months does not help improve the sperm quality among infertile men as previously thought and thus cannot be considered as a therapy.

According to the authors, spermatogenesis — production or development of the mature spermatozoa — and transport together take approximately 74 days, but that reactive oxygen species have a greater negative effect during the much shorter sperm transport phase rather than during spermatogenesis, thus antioxidants are thought to have benefit even after a short interval.

“The results do not support the empiric use of antioxidant therapy for male factor infertility in couples trying to conceive naturally,” said Anne Steiner, Professor at the University of North Carolina at Chapel Hill, US.

For the study, presented at the 34th Annual Meeting of ESHRE in Barcelona, the team conducted clinical trail of 174 couples where the male partners took daily antioxidant supplement in tablet form containing vitamins C, D3 and E, folic acid, zinc, selenium and L-carnitine, while the control group received a placebo.

The findings showed only a “slight” overall difference in sperm concentration between the two groups, and no significant differences in morphology — the shape and size of the sperm cells –, motility — the ability of sperm to swim or move –, or DNA fragmentation measurements — damage in the DNA of the sperm.

Further, the natural conception rate during the initial three month was 10.5 per cent in the antioxidant group and a little more than nine per cent in the placebo group, the researchers said. (IANS)
