I am an expert in traditional Chinese medicine. Eating too much fermented grains will make you fat, and brown sugar will promote blood circulation, but it depends on whether you eat authentic brown sugar. If it is industrial brown sugar in the supermarket, it will definitely be fat. You don't have to eat it every day. Can be eaten before and after menstruation, can regulate menstruation. Too much menstruation stops! You don't have to eat it every day, it's too tonic! You still have to live within your means to avoid getting fat.
