Grapefruit, a fruit full of vitamin C

Grapefruit is a citrus fruit with a taste that can range from bittersweet to sour. It contains a number of essential vitamins and minerals. People can consume the fruits whole or as juice or pulp. Grapefruit first appeared in the 18th century as a result of crossing pomelo and orange. People called it “grapefruit” because it grows in clusters, similar to grapes.

Each cluster on the tree produces upwards of 12 to 20 grapefruits at a time. Its flesh is usually light yellowish, soft and full of juice, with a distinct slightly sour taste. A few varieties have pink or red flesh.

How to consume grapefruit on its own?

You can consume grapefruit in two ways . Either cut it in half horizontally and eat each segment with a spoon, or peel it with your hands or a knife and cut into segments (similar to eating an orange). Some people sprinkle sugar on top to balance out the sour taste, but that’s not exactly healthy.

If you still like to sweeten your grapefruit, try using non-caloric stevia instead of sugar. Another option is to use salt . The salt makes the grapefruit sweeter. It blocks the bitter receptors on our tongue. Salt also makes it easier for volatile compounds to get into the air, which means you can smell more grapefruit and that will increase the perception of sweetness.

Grapefruits should be rinsed under cold water before eating, even if you won’t be eating the skin, because cutting into unwashed fruit can transfer dirt or bacteria that may be on the surface of the skin to the edible flesh.

In addition, they are usually coated with a thin layer of wax to prevent moisture loss. Organic grapefruits are also coated with wax, but from an organic source such as palm oil.

You should eat grapefruit in the morning. Avoid consuming it at night as it can cause heartburn.
