What is cacao?
Cacao is known as the food (or drink) of the Gods! It has been traced back to the Maya people who were thought to be the first to cultivate the cacao plant around 400AD. The plant that is recognised today is actually a result of cross selection that started over 35,000 years ago and the scientific name is Theobroma cacao.
100% cacao has a rich, chocolate flavour but is also very bitter. The taste of cacao can actually vary depending on the variety of plant, soil, temperate, sunlight and rain that is received during the growing process.
Once the cacao bean has been processed (cold pressed, unroasted beans) – you can end up with raw cacao powder, cacao nibs (the outter husk) and cacao butter (the oils of the beans).
Raw cacao health benefits
Be sure to note here – the benefits we are going to talk about all relate to raw cacao and cacao dark chocolate. We are not talking about sugar and dairy laden milk chocolate!!!
One of the greatest health benefits of cacao comes from the flavonols (a class of flavonoids – antioxidants) that are found in cacao. Schardt notes that “Flavonols are bitter tasting, so to make cocoa more palatable, chocolate manufacturers roast, ferment, pulverise and sometimes alkalinize the beans or cocoa…unfortunately, this processing can destroy a lot of the flavanols”.(2013)
Antioxidant – Heart and Renal Health
- Cacao is a powerhouse FULL of antioxidants! The flavanols found in cacao can increase nitric oxide bioavailability, activate nitric oxide synthase and exert anti-inflammatory and anti-platelet activity – all of which may improve vascular function and reduce blood pressure.
- Cacao has been studied for its ability to reduce blood pressure and has been shown to produce “a small but statistically significant effect in lowering blood pressure by 2-3mm Hg in the short term” (Schardt, 2013)
- It has also been shown that the consumption of dark chocolate can increase renal medullary oxygenation and therefore may be a renal (kidney) protective agent.
Happy, Happy, Happy + Energy
- Eating cacao makes you happy! It contains phenylethylamine which is responsible for our state of mood and pleasure and the same feelings you get when you are in love. It also acts as a stimulant and can improve mental alertness.
- Cacao also contains serotonin and dopamine – which also stimulate good mood and ‘pleasure’ feelings.
- Anandomide is also in cacao which is present in the brain as an endogenous substance and interacts with cannabinoid receptors.
Nutrients in cacao
- As we mentioned above, cacao is a powerhouse antioxidant and rates in the top 20 on the Oxygen radical absorbance capacity (ORAC) scale. The ORAC scale is used to rate the antioxidant capacity of foods.
- Cacao also contains great levels of magnesium, which is an essential mineral during times of stress and helps you to feel more relaxed. It also contains manganese, zinc, calcium and potassium.
- Raw cacao even contains good levels vitamin C!
Cacao/cocoa butter skin benefits
- Cocoa butter has been widely used to reduce or prevent stretch marks. There is no substantial clinical evidence that it really works but the butter provides deep hydration and antioxidants to fight free radicals so we’d definitely use it to keep our skin supple and moist, which in turn can prevent or reduce the appearance of stretch marks.
- It has been noted to help with sensitive skin problems such as irritations, eczema and dermatitis.
- Raw cacao is a stimulant so it is advised not to consume it after about 2-3pm as to not interfere with a good night’s sleep!
- Researchers at the Agricultural Research Service found that the higher cacao content of chocolate the higher the benefits of the antioxidant properties found. So the darker – the better J
- It has been reported that dairy in chocolate reduces the bioavailability of the flavonoids found in cacao. It should be noted that the jury is out on this one! There are studies for and against – so I’m not convinced either way just yet. At Rejuvenated for Life we acknowledge that there are many people who benefit from following a dairy free diet, as it can cause an inflammatory response in a lot of people and so for now would hedge our bets that you would be receiving more benefit from consuming chocolate and cacao that is dairy free.
- There is such a thing as ‘chocolate poisoning’ or ‘theobromine poisoning’, which is an overdose reaction to the alkaloid found in cacao. Theobromine has an effect primarily on the central nervous system and cardiovascular system, as well as on respiratory system and acting as a diuretic.
- Although the risk is very small and it would be very hard to consume enough theobromine to make yourself sick – it is just a reminder that anything eaten in extreme quantities is not good for you! This is why pets such as dogs can’t eat chocolate; it is the throbromine that makes them so sick.
Where to get raw cacao
You can find raw cacao powder and cacao butter in most health food stores these days and even at some major supermarkets.
You can find raw chocolate at good health food stores, variety stores or online. Just be aware of the sugar content and still look out for the highest percentage of cacao.
Dark chocolate can be hard to get used to if you try to switch straight from milk chocolate to 90% cacao. The best tip is to gradually start buying chocolate that has a higher percentage of cacao, say by about 10-20% every month. Dark chocolate is very palatable once you get used to it. It takes 21 days to change your tastebuds, so before you know it, you will be eating 95% dark chocolate.
Cacao nibs add a lovely crunch to muffins, ice-cream or as a topping on your favourite dessert. They are also great to add to your favourite granola mix for breakfast or on top of a smoothie.
Will cooked raw cacao retain its benefits?
There is no scientific verdict on whether raw cacao’s nutrients diminish during heating. We recommend using is in its raw form as much as possible but even if you cook with it, it will still be more beneficial than the already processed and heated cocoa powder.
