13. Citrus Fruits
citrus fruits include mandarins, oranges, limes, lemons and grapefruit – they are so varied, that you can find them all year round. Really, there’s no excuse why not to eat them. A popular use for citrus fruits is making juice or shakes, and 3 percent of the citrus fruit in the world is used to squeeze juices!
You might know this about oranges, but all citrus fruits are rich in vitamins, particularly vitamin C, which strengthens our immune system – that’s why drinking fresh orange juice can perform as a natural remedy to avoid a cold or flu. It’s advised to eat or drink citrus fruit all year round, but especially when you’re feeling under the weather, as it strengthens your body.
