We are constantly bombarded with information about what we should and shouldn’t be eating which can become confusing.

Caymanrestaurants.com has decided to go for a simple approach and provide an alphabetical guide to some of the healthiest foods you can add to your diet.

We’ll be going from A-Z and listing up to five fruits and vegetables that are packed with minerals and vitamins while also providing nutritional facts on their health benefits.

We’ve looked at A-J. Let’s move on to K.


Kale is native to the UK and Eastern Mediterranean countries and is a member of the cabbage family. It comes with curly and smooth leaves and there are several varieties.

Kale is a superfood because it’s full of antioxidants and anti-inflammatory properties. It also contains isothioctanates which have been proven to reduce the risk of developing some cancers such as bladder, breast, colon, and ovarian.

Kale is also a great source of vitamin B6, potassium, fibre, copper and calcium.

Kefir is a cultured, fermented probiotic milk drink that’s made by adding kefir grains to cow, goat, sheep, or even coconut milk.

Kefir grains look like cauliflower. They aren’t grains at all but rather small gelatinous beads that contain a variety of bacteria and yeasts.

Kefir is a better source of probiotics than yogurt and is also rich in calcium. Due to its fermented nature, it is recommended that you purchase kefir from a reputable source because if it’s not made properly it can make you ill.

Kiwifruit is native to China and was initially known as Chinese gooseberry when it was first shipped to New Zealand at the beginning of the 20th Century.

When New Zealand began exporting the fruit its name was changed to avoid excessive duties on berries. It was called Kiwifruit because it resembles New Zealand’s national bird which is also brown and furry.
