Ca 2.5. The lemon has a pH of around 2.5, but the pH of Coca-Cola hits 2.4 with its phosphoric acid. When it comes to alkaline drinks, you won't find many.

Violet. Since the ancient times, a black carrot has been grown in Asia (var. Atropururea), which was also brought to Europe during the Middle Ages. Through seventeen centuries, almost all of the carrots that were grown were violet. The modern carrot, a result of mutation, was first grown in the Netherlands. As it was sweeter and bigger, it quickly replaced the violet variety.

Buffalo. Water buffaloes provide 11% of the world's milk, which is much more than goats (2%, third place).

The top buffalo milk producers are India and Pakistan.

Blood plasma. The story of coconut water being similar to human blood plasma originated during World War II when British and Japanese patients were given coconut water intravenously in an emergency because saline was unavailable. Since then, this rehydration technique has been used only for short-term emergency situations in remote locations where plasma is not available.

Saffron is a spice derived from the flower of the saffron crocus. It takes about 150 000 of flowers to harvest 1 kg of stigmas used as spice.

A sugar. Lactose is a disaccharide sugar that makes up around 2-8% of milk. Lactose intolerance is not an allergy. It is the inability to digest lactose due to insufficient levels of lactase, the enzyme that metabolizes lactose into glucose and galactose.

Mars & Murrie. The letters M stand for M&M's creators: Forrest Mars, Sr. (the son of Chicago candy maker and Snickers bar creator Franklin Clarence Mars) and Bruce Murrie (the son of William Murrie, president of the Hershey Company). The idea for the candy was copied by Mars from British soldiers during the Spanish Civil War.
