What could make us feel worse:
Alcohol - People with GS seem sensitive to alcohol to differing degrees. The best advice is to be aware that it can cause stress to your liver and see how much or little your body is happy to process.
Fatty foods – digestive problems seem common in GS and some people find fatty foods put a lot of stress on their digestive system.
Sugary foods and refined carbohydrates – these mess with the bodies energy levels, and if you’re suffering with fatigue then these won’t help balance your energy. Plus Sugar
can impair your liver’s ability to detoxify.
Other suspects include – fluoride, peppermint, vanilla, menthol and the B vitamin niacin (on its own, but ok with other B vitamins)
Artificial sweeteners – can cause an increase in the ‘brain-fog’ experience
