September 14, 2012 - A new study suggests having a blood sugar level that's even on the "high end" of normal could have damaging effects on the brain. Researchers from the Australian National University found that people whose blood sugar was in the high end of a normal range (but not yet in the range for diabetes or prediabetes) were more likely to experience brain shrinkage in the hippocampus and amygdala, an effect that normally occurs when a person ages, or experiences dementia. According to the Mayo Clinic, when blood sugar gets too high, it can negatively affect blood circulation and cholesterol can build up within the blood vessels, leading to health issues like nerve damage, eye and kidney problems, gum disease, heart attack and stroke.
Also, if you buy organic fruits and vegetables, you know they often cost a lot more than conventionally grown produce. But is it worth it?
Stanford University researchers looked at data from hundreds of previous studies. They found there's practically no nutritional difference between organically and non-organically grown produce. But if you consider the use of pesticides, there's a big difference. The study found that organic fruits and veggies had a 30 percent lower risk of pesticide contamination than non-organic. However, no studies found specifically that pesticides at non-organic levels cause harm.
