Brisbane: Easter chocolate is all over supermarket shelves. Some people reach straight for milk chocolate eggs while others pause at the darker varieties, assuming they’re healthier.

Dark chocolate has gained a reputation as the “better” choice because it usually contains more cocoa and less sugar than milk chocolate.

But is dark chocolate actually healthier? Let’s see how the evidence stacks up.

How do they compare?

All chocolate begins with the cocoa (or cacao) bean. Cocoa beans are the seeds of the Theobroma cacao tree, a tropical plant native to Central and South America.

Processing the bean gives you cocoa solids (the bitter part) and cocoa butter (the fat part that gives chocolate its smooth texture).

Chocolate is made from cocoa solids, cocoa butter and sugar. Milk chocolate also contains milk powder or condensed milk.

Dark chocolate typically contains a much higher proportion of cocoa solids, usually 50–90 per cent.

Milk chocolate generally contains 20–30 per cent cocoa solids, with the remaining bulk made up of milk ingredients and sugar.

How about nutritional benefits?

Because dark chocolate contains more cocoa solids than milk chocolate, it naturally provides slightly higher amounts of certain minerals.

This table shows the differences between milk chocolate (30 per cent cocoa) and dark chocolate (more than 60 per cent cocoa) per 20-gram serve. That’s about one row of a Lindt chocolate block.
