Botanical definition of berry
In botany, a berry is any kind of fleshy fruit that comes from a single flower and has a single ovary, including tomatoes, avocados and bananas. In everyday speech, however, we don't think of these as berries. We use the word mostly for small, round sweet or tart fleshy fruits with small seeds that grow on vines, bushes or trees. Examples are grapes, cranberries, strawberries, blueberries and cherries.
Personal preferences on fruits
My favorite fruits are almost any kind of berries: strawberries, cranberries, blueberries. I love how colorful and sweet they are.
Mixed berry is the best flavour of juice. It's usually a mixture of blueberry, strawberry and cherry. It's very sweet and red in colour. It's supposed to have a lot of vitamins too.
There is a popular expression with the word berry. When someone's skin has become much darker from the sun, you can say they are brown as a berry.
Joshua came back from Italy last weekend and he is as brown as a berry. He must have spent every day in the sun there.
I can't wait for my holiday. I'm going to lie on the beach as much as I can to get a suntan. I hope to come back as brown as a berry.
Citrus fruits and benefits
A group of fruits that grow on small trees or shrubs and have a sweet or sour taste and a thick skin or peel are called citrus. Examples include oranges, lemons and limes.
The doctor told us that we should be eating more citrus fruits like lemons and oranges, because they are very high in vitamin C and other antioxidants that are good for the immune system.
Sarah doesn't really like citrus fruits because they are too acidic. She says they often have a sour taste and they irritate her mouth. That's why she prefers bananas or pears.
Acidity of citrus and preservatives
Most citrus fruits contain citric acid. This is the weak organic acid, or chemical with a pH of lower than 7. It is widely used as a preservative or chemical added to food to keep it from spoiling.
This juice is good, but it's not the same as freshly squeezed juice. They have added salt and citric acid as preservatives.
I love the bread from the Main Street Bakery, but you really have to eat it fast. It starts to spoil within just a couple days because they use no preservatives to prevent that.
