Yes it's very good to eat cucumbers everyday if you want too.
I love eating cucumbers and what I do is slice up a few cucumbers and put them in the refrigerator to keep them cool.
Then I take cucumbers to work with me and then snack on the cucumbers throughout the day when I'm feeling a bit hungry.
The cucumbers make a very healthy snack to eat during the day and sometimes I'll add sliced up cucumbers to salads as well.
I've been eating at least 2 cucumbers per day everyday as a snack when sliced up for around 10 years now when at work and I've been very healthy.
Cucumbers are very nutritious and are a good antioxidant for your body as well so you'll benefit your health when eating cucumbers everyday.
