Health Benefits of Leeks: Good For the Heart, Cancer Protection

Leeks are full of health benefits!  Before living in England, I had never heard of or seen leeks but now they are in all the supermarkets here.  They are one of the many healthy superfoods to include in our meals. Leeks belong to the same family as onions and garlic.

Leek health benefits research has been minimal so most of the benefits of leeks are because of them being in the onion and garlic family, which they share many of the same benefits. They are full of so many impressive health benefits which really surprised me.

The strong and mighty eat their Leeks
That is why they are not Weak.
Be like a poet wise and Meek
Eat healthy food and clearly Speak
Wiser words than the Romans or Greeks!
As you glow with the Health many Seek!

How to Grow Leeks

Would you like to grow leeks? They are easy to grow but you may not get such large ones as you just saw in the video above.

First, let’s start by sowing the seeds thinly in potting soil about an inch apart. Cover the seeds with a thin layer of more potting soil, and water them. It is important to keep the potting soil moist so the seeds can germinate and grow.

Place them on a sunny indoor windowsill or in a greenhouse to help them grow.  You can pot them on into individual pots as they grow.

They like moist, light soil with a good quality of well-rotted organic compost.  It is best that the soil is not rich as they will grow coarse and tough with far too much leaf growth.

Best to not grow leeks in the same place every year as there will be a risk of diseases.


  • They are native to Central Asia and have been grown there and in Europe for thousands of years.
  • Ancient Romans and Greeks valued leeks for the health benefits for the throat.
  • They were brought to the United Kingdom by the Romans and grew well as they could survive the colder winter weather.
  • Now here is the best fun leek fact ever: let’s see the largest leek ever to be grown.

Below is a video below showing an amazingly large leek!

Select the Best Leek

Select firm, straight ones with dark green leaves and white necks. Stay away from yellow wilted leeks or ones with cracked or bruised bulbs. Choose leeks with a width of one and one-half inches or less as extra-large leeks can be too fibrous in texture.  

How to Store

Best to store them untrimmed and not washed in the refrigerator for one to two weeks. Wrap them loosely in a plastic bag so they don’t dry out.

Do note that when you have cooked leeks they will not last more than two days in the refrigerator. You can keep leeks in the freezer for three to four months.
