People with type-2 diabetes get no benefit from taking omega-3 fish oil supplements, a new study has found. According to researchers from the University of East Anglia, while omega-3 supplements are not harmful for people with type-2 diabetes (this has been a concern previously), they don’t provide any benefit either. This contradicts a common belief that omega-3 can protect against diabetes and even reverse the condition. The study, which involved 58,000 participants, found that people who consumed more omega-3 had the same risk of developing diabetes as individuals who did not. Furthermore, taking omega-3 fish oil did not influence levels of blood glucose, insulin and glycated haemoglobin - all measures of how the body handles sugar. ‘Better to eat fish’ Douglas Twenefour, deputy head of care at Diabetes UK, said: “Eating a healthy, varied diet is incredibly important, and we know that certain foods - including fruits, vegetables, wholegrains, yoghurt and cheese - can help to lower your risk of type 2 diabetes. “While omega-3 fatty acids are crucial for our overall health, it's generally better for people with type 2 diabetes to get their intake by eating at least two portions of oily fish a week, than by taking supplements." The advice from Dr Lee Hooper, who led the research, is to forego the expensive omega-3 supplements and instead buy oily fish and/or spend your money on physical activity, which will have more of a positive impact when it comes to type-2 diabetes.
We recently wrote about how foods packed with good bacteria provide no benefits. Now, new research is dragging yoghurts under the spotlight because of the amount of sugar many contain. In fact, according to the research led by Leeds University in the UK, some yoghurts contain more sugar per 100g than cola. Publishing their findings in the journal BMJ Open, the team of researchers said that even organic yoghurts often contain way too much sugar. The only yoghurts, they said, that can be considered low in sugar are natural and Greek-style. For the research, the team analysed 900 different yoghurts on sale in supermarkets in the UK. Perhaps unsurprisingly, yoghurt deserts were found to contain the most sugar (an average of 16.4g per 100g). More surprising, though, are the findings relating to organic yoghurts. That’s because many people see them as a healthy option, not knowing they contain so much sugar. The UK government are trying to reduce the amount of sugar consumed by the public and yoghurts are one of the areas they want to see addressed. This new research underlines why. To be classed as ‘low sugar’ a product needs to contain no more than 5g of sugar per 100g. Just 9% of the yoghurts studied were found to be below this threshold. Dr Bernadette Moore, lead researcher of the study, said: “I think people, including parents, will be surprised to know just how much sugar there is in yoghurt. “My advice would be to buy natural yoghurt and mix in your own fruit.”
The modern, germ-free lifestyles many children lead could be responsible for the most common type of cancer in children - acute lymphoblastic leukaemia - according to one of the UK’s most well-respected scientists. Professor Mel Greaves, from the Institute of Cancer Research, has been studying for 30 years how the immune system can become cancerous if it is not exposed to enough bugs early in life. Acute lymphoblastic leukaemia affects one in 2,000 children and is more common in advanced, affluent societies, suggesting cleaner modern lifestyles could play a defining role. Prof Greaves says the disease happens in three stages: a genetic mutation inside the womb, a lack of exposure to microbes in early life and an immune malfunction and leukaemia in childhood. He believes that it could be possible to prevent the condition. Prof Greaves said: "The research strongly suggests that acute lymphoblastic leukaemia has a clear biological cause and is triggered by a variety of infections in predisposed children whose immune systems have not been properly primed." Unfortunately, preventing the disease isn’t as simple as exposing children to dirt. They need, according to Prof Greaves, contact with beneficial bacteria. The best way to do this is to give them a safe cocktail of bacteria, such as in a yoghurt drink, that will help boost their immune system.
