Raw cacao is one of the highest plant-based sources of magnesium, the most deficient mineral in the Western world. Magnesium is important for a healthy heart and helps turn glucose into energy enabling your brain to work with laser-sharp clarity and focus. This might just be the reason your body craves cacao when you're pulling an all-nighter! Last but not least, cacao contains more calcium than regular cow's milk. Cacao has 160mg per 100g vs only 125mg per 100ml of milk. Cacao is also a great source to help combat depression. Cacao is a great source of four scientifically proven bliss chemicals – serotonin, tryptophan, tyrosine and phenylethylamine. These neurotransmitters are associated with cosy feelings of wellbeing, happiness, and can even alleviate depression.
