A Neurologist claims that grains are silent brain killers and we shouldn't be having them. Instead we should be consuming a high fat diet. He states that even good carbs such as grains raise the risk of dementia and depression.
Foods we should be eating are those which are ancestors ate, meat and fat. Is this why the paleo diet is so successful and is quickly becoming the ' in thing'? I believe that carbohydrates have a role to play but are they necessary for everyone? Possibly not, but it is down to you to figure out what works best for your body.
