Question: Many people have different opinions on chocolate. Some say it is healthy, some say it is not. What do you think?

Quantity is the first key point, anything more than about 20-30g is probably too much. Then the challenge is getting enough of the good compounds called flavanols into this amount of chocolate, as it can make it very bitter. Currently very few shop bought chocolates can do this.
I don’t think any food is bad, it’s just easier to eat too much of some foods like chocolate. As scientists we need to work out how to make foods better and healthier.
