A dose of dark chocolate a day will keep the doctor away!

Since we are talking about chocolate, this is a very serious matter and needs to be treated with care. I’m not talking about the processed dark chocolate with copious amounts of sugar in it, but the dark chocolate with at least 50% cacao within it, which has been manufactured in a way such that the flavonol concentration inside it is not depleted.

Coffee has evolved twice!

The coffee genome has just been published. Denoeud et al have sequenced the genome of coffee (biological name Coffea canephora). They found that within coffee’s 11 chromosome pairs, that there were many duplicated genes which include the one that code for the production of caffeine. They also suggested that these duplications enhance the products produced by the coffee plant to produce more effective proteins. The research also found that unlike tea and cacao (the chocolate component), the genes that code for the production of caffeine, in the coffee plant, are different to the genome sequence for the tea and cacao caffeine-producing enzymes, defining that the caffeine production genome has evolved at least two times. The genome sequence could help in research to help identify the genes that help the plant to combat diseases (related to the plant) and to also cope with climate change and to also encourage more delicious tasting coffee!

Coffee: the Good, the Better and the Not-So-Good

Millions of people over the world start their day with an aromatic cup of coffee generally to wake them up.  Coffee contains caffeine which is the stimulant that interacts with the body to make you feel more alert. How Coffee works and its benefits Caffeine works as an antagonist (block receptors) of adenosine receptors in the brain. Caffeine mimics the natural neurotransmitter; adenosine, and blocks the receptor, preventing adenosine from binding to the receptor and slowing the nervous impulses. In turn this makes the nervous impulses quicker and the brain works faster. Also caffeine can relieve headaches and migraines since it binds to adrenergic receptors on vascular muscle cells which cause them to constrict instead of dilating.

Coconut water: healthy or hype?

Social media is full of health gurus that are obsessed with healthy eating and exercise and what they can drink to maintain their energy during workouts. This is where coconut water comes in. Coconut water (biological name Cocos nucifera L.) is sometimes compared to energy drinks and glorified about for its great benefits and hydrating properties. It is even now more widely available in grocery stores than previous years. The hydrating drink is known to have a bunch of nutritious benefits and is harvested from green coconuts that are still unripe. Coconut water is low in calories, rich in antioxidants and electrolytes (such as the inorganic ion: potassium), it is also low in fat and cholesterol free and has elevated amounts of vitamin C .

Vitamin C Does Nothing for Your Cold But it can put off Cancer

Everyone thinks that if they have the common cold or flu if they increase the dose of vitamin C in their diet (via copious amounts of orange juice, honey and lemon tea, and vitamin c supplements etc etc…). As a kid I used to take these chewy Vitamin C pills in the hope that they would help prevent me from catching the cold from school especially at every new term start but to my dismay; I still caught the cold. So does vitamin C actually work? Studies have stated that although vitamin C does not prevent the common cold but it actually can reduce the severity and duration of it. The Chemistry of Vitamin C Vitamin C is also known as ascorbic acid. Ascorbic acid is known to have anti - carcinogenic properties. In English that means that it can prevent cancer in the body. Vitamin C reacts with organic free radicals to protect from the damage caused by free radicals in cells.
