Chocolate
Powerful antioxidants found in chocolate, especially dark chocolate, have been shown to improve circulation and decrease blood pressure. Unfortunately, it is also known to cause migraines and IBS symptoms in some people.
Chocolate has historically been thought to be a potential cause of gut symptoms like diarrhea, gas, bloating, cramping, and pain. This is because chocolate, especially milk chocolate, contains a lot of sugar, milk proteins, fat, and lactose, all of which can make people sick. Consuming chocolate can cause constipation in some people. Most people can tolerate small amounts of chocolate and other sweets, but if you have lactose intolerance or IBS, the more you eat, the more you tempt fate. People with IBS frequently find some vegan chocolate options to be more tolerable.
