It seems sugar could have the same effect on your brain as cocaine – it can be just as addictive as the powerful illegal drug and can cause cravings and binges, the British Journal of Sports Medicine reports. Research has found consuming sugar produces drug-like effects. And it’s not easy to give up either. Cutting out sugar can result in withdrawal symptoms similar to a drug addict going cold turkey, and could lead to depression and behavioural problems such as ADHD. The tests were conducted on rats, but the researchers say the results would be true for humans too.
