 Now that’s what I call a long list of fruits! But here’s the best part – the wide variety of citrus fruits that you can get your hands on also means that you get an equally wide variety of health benefits. Don’t believe me? Then just keep on reading…

What Are The Health Benefits Of Citrus Fruits?

  1. They aid weight loss as they have a high water and fiber content, which keeps you full for a long time. This fiber also boosts heart health and prevents cardiovascular disease.
  2. Citrus fruits can help reduce the risk of esophageal, stomach, and ovarian cancers.
  3. They reduce your risk of developing cataracts and age-related macular degeneration.
  4. The vitamin C in citrus fruits helps regenerate collagen that maintains the elasticity of your skin. Hence, these fruits can help delay the signs of aging.
  5. They help reduce the overall duration of the common cold by a day.

But wait a minute! While it sure is great that citrus fruits give you a wealth of nutrients, you need to keep in mind that you can obtain their benefits only if you select the right fruits at the market, store them properly, and eat them before they start rotting. Here’s what you need to do…

What Are Some Healthy Ways To Eat Citrus Fruits?

When it comes to taste, no fruit can beat the perfect blend of sweet, sour, and slightly bitter flavor notes of citrus fruits. You can simply peel and eat them out of hand, drink their freshly squeezed juice or incorporate them in a ton of healthy and simple recipes!

  • When I watched The Jungle Book as a kid, I absolutely fell in love with the idea of plucking fruit straight off a tree and devouring it because of how delicious it looked when Mowgli did it. Now you may not have the option of picking your citrus fruits off a tree, but you sure can eat them the way God intended you to. Most citrus fruits also have the added advantage of having a loose peel that can be removed by hand and being naturally divided into bite-sized segments. So you don’t need to mess around with knives or forks! Eating citrus fruits this way also ensures that you don’t miss out any of the fiber and great nutrients that they pack. The best time to eat citrus fruits is right in the morning with a glass of milk. And if you’re diabetic, make sure there’s a gap of a couple of hours between your meals and citrus fruit consumption because otherwise, it could raise your blood sugar level too much.
  • For those of you who prefer drinking juices instead of eating fruits (like me!), freshly squeezed citrus fruit juices are going to be your new best friend. But don’t you dare strain out the pulp before chugging that juice! The pulp of citrus fruits contains fiber that has the all-important pectin that is responsible for getting rid of cholesterol from your body.
  • Add peeled segments of any citrus fruits you like to your salad, a bowl of low-fat yogurt or chia seed pudding to add a dash of sweet and tangy freshness to an otherwise boring meal!

While these are some super simple ways to enjoy citrus fruits, you can also prepare some yummy dishes with them that will make you a hit with your family and friends. Below are just a few dishes that you can try out.
