Caffeine is the most widely consumed psychoactive substance in the world. It is highly addictive and causes unpleasant withdrawal symptoms (headaches being the most common) if you stop drinking it suddenly. Most people get their caffeine fixes from coffee and tea, but it is also present in cola drinks, energy drinks and chocolate (the darker the chocolate, the more caffeine it contains).

Caffeine is a strong diuretic and can cause insomnia, tremors and reduced fertility in men. It's bad news for pregnant women too.

People all over the world rely on it each morning, yet many of the 25 million small-holder coffee farmers who depend on it for their livelihoods struggle to survive. Wide price fluctuations year-to-year, changing weather conditions, difficulties with disease, and lack of bargaining power often leave farmers receiving as little as three cents from a $3 cup of coffee.

Organic systems recognise that our health is directly connected to the health of the food we eat and ultimately, to the health of the soil. Organic farmers aim to produce good food from a balanced living soil. They severely restrict the use of synthetic chemicals, pesticides and fertilisers. Animals are reared without the routine use of drugs including synthetic growth hormones, antibiotics and wormers, which are commonly used in intensive livestock farming.
