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.

Hot Coffee Has Higher Levels of Antioxidants Than Cold Coffee

And considering hot and cold brews have comparable pH levels, coffee drinkers should not consider cold brew a 'silver bullet' for avoiding gastrointestinal distress

Hot coffee has higher levels of antioxidants than cold coffee, which are believed to be responsible for some health benefits, says a new study.

The study explored that hot coffee has some measurable health benefits, including lower risk of some cancers, diabetes and depression.

For the study, researchers from Thomas Jefferson University in the US showed that hot coffee had more total titratable acids — any acid that can lose proton(s) in an acid-base reaction — which may be responsible for the hot cup’s higher antioxidant levels.

“Coffee has a lot of antioxidants. If you drink it in moderation, research shows it can be pretty good for you. We found the hot brew has more antioxidant capacity,” said Megan Fuller, an Assistant Professor from the varsity.

Results published in the journal “Scientific Reports” also found that pH levels — acidity indicator– of both hot and cold coffee were similar, ranging from 4.85 to 5.13 for all coffee samples tested.

However, coffee companies and lifestyle blogs have tended to tout cold brew coffee as being less acidic than hot coffee and thus less likely to cause heartburn or gastrointestinal problems.
