Consuming blueberries can slow ageing and help in improving vision and memory, says a new study. “Eating blueberries can also curb risks of developing cancer as well as reduce the chances of heart diseases,” Shuyang Qu, Doctoral Student at the University of Florida Institute of Food and Agricultural Sciences in the US, said in a statement.

The researchers wanted to determine how much consumers know about blueberry health benefit and see if there is a knowledge gap with blueberry health benefits among demographic groups.

They surveyed more than 2,000 people in 31 US states to see what they know about the health benefits of blueberries.

The researchers found that most people were aware of the benefits of blueberries in cancer prevention and lowering the risk of heart disease but they are less aware of the advantages of reverting aging, improving vision and memory.

"People being more familiar with blueberries as deterrents for cancer and heart disease may be related to the high general awareness of these two diseases," said lead researcher Shuyang Quad, doctoral student in agricultural education and communication at University of Florida Institute of Food and Agricultural Sciences, in a statement.

"The fact that cancer and heart diseases are the leading causes of death in America may have led to more personal research related to preventing the diseases, leading to the respondents being exposed to these findings more than other benefits,"
