Eating chocolate is beneficial in some ways but we have to talk about its negative effects. Chocolate is toxic due to its theobromine content. Dark chocolates have been found to contain higher amounts of this chemical, hence, the need for us to be cautious so as not to eat too much of it.
Caffeine and theobromine are both present in chocolate and they are the reasons why eating chocolates has a lot of benefits. Some of the benefits of chocolate include: weight loss, reducing stress, boosting calorie levels, asthma treatment etc.
Eating too much of chocolate has been found to pose serious health risks. Some of the negative effects are: insomnia, ulcer, burning sensation in the chest, anxiety/nervousness, inflammation of the oesophagus etc. These negative effects are worth considering.
