FOOD FACTS

Feel Good With 7-Up

 7-Up – invented in 1920 contained Lithium – the drug commonly prescribed now to sufferers of bi-polar disorder.

The drink was originally marketed as a hangover cure – due to the inclusion of lithium citrate. It was released just a few years before the Wall Street crash of the 1920s and it was marketed under the name “Bib-Label Lithiated Lemon-Lime Soda” – quite a mouthful! The name was changed to 7-Up shortly after its release but lithium remained one of the ingredients until 1950. Some popular myths surround the name of the drink – but the name is most likely due to the original recipe containing 7 ingredients (with the “up” portion relating to the lithium) or the fact that lithium has an atomic mass of 7.

Ancient Sauce

Ketchup was originally a fish sauce originating in the orient.

Two words from the Fujian region of China were used to describe a fish brine / sauce and a tomato sauce – both words bear a striking resemblance in sound to the word “ketchup”; the words are: ke-tsap and kio-chiap. Early western ketchups were made with fish and spices, or mushrooms. In fact, mushroom ketchup is still available in the United Kingdom and it is prized by some modern chefs for its natural inclusion of monosodium glutamate – the only substance known to stimulate the 5th human taste sense umami (savoury).

Brain Freeze

The term “brain freeze” was invented by 7-11 to explain the pain one feels when drinking a slurpee too fast.

Believe it or not, there is a real scientific name for “brain freeze” – it is sphenopalatine ganglioneuralgia (try saying that 5 times fast!) When something very cold (usually ice cream) touches the top palate of the mouth, it causes the blood vessels to constrict. This makes the nerves send a signal to the brain to re-open them. The rapid re-opening of the vessels causes a build up of fluid in the tissues causing a slight swelling in the forehead and, therefore, causing pain. It normally takes 30 – 60 seconds for the fluid to drain, relieving the pain.

vanilla

 The consumption of natural vanilla causes the body to release catecholamines (including adrenalin) – for this reason it is considered to be mildly addictive.

When vanilla plants were first exported from Mexico to other tropical climes, they flowered but wouldn’t produce vanilla pods. It was discovered that a bee native to Mexico was the only creature that could pollinate vanilla flowers (vanilla comes from a special species of orchid). Attempts to move the bee to other countries failed and it was not until a slave boy discovered a method of artificial pollination that Mexico lost its monopoly on vanilla. As well as being mildly addictive, vanilla has also been found to block bacterial infections.

SECRET BEHIND EGGS

When an egg floats in water, it is “off” and should not be eaten.

As eggs age, gases build up inside the shell making it more buoyant. This is the best way to test whether an egg has gone rotten without having to break open the shell, risking the foul odor escaping. When an egg is extremely fresh it will lie on its side at the bottom of a glass of water. As it ages, the egg will begin to point upwards, and will finally float completely when it has gone bad. Fresh eggs have a very firm white, whilst old eggs have a very watery white. This is why it is best to use the freshest eggs possible for poaching and frying. Older eggs are perfectly good for omelets or scrambling.

Apple, Potato, or Onion?

Apples, potatoes, and onions all taste the same when eaten with your nose plugged.

As a child we had a science class in which we were blindfolded, had our noses plugged, and given an apple or onion to eat – we were not told which of the two we would be given. Not one person was able to state which was which. This shows the incredibly important part that the nose plays in the sense of taste. The fact that the three items have a similar consistency makes it virtually impossible to tell them apart without the sense of smell. If you try this, I should warn you: once you unblock your nose, you can tell what you have just eaten.
