8 Surprising Health Benefits of Cucumbers
So why should you eat a cucumber every now and then? Let’s summarize the top health benefits of cucumbers:
1. Packed with Vitamins
Cucumbers are a great source of different B vitamins, also called the B vitamin complex. In general, B vitamins help our bodies running like well-oiled machines, convert our food into fuel, and help us to stay energized.
While not a vitamin C superstar, the skin does contains a good amount of this essential nutrient also. Even more so, cucumbers are a great source of vitamin K, which helps to form blood clots and prevent excessive bleeding.
2. Good for Your Skin and Hair
Because the cucumber has such a high water content, it has a naturally strong hydrating effect, which is good news for our skin! The cucumber and our skin also share the same level of hydrogen, which makes them a perfect match.
Cucumber helps in soothing and cooling our skin, especially around sensitive or dry areas, such as the eyes.
Certain nutrients in cucumber, such as magnesium, potassium, phosphorus and calcium, are believed to be beneficial for our hair.
3. Helps Prevent Disease
According to WHFoods, cucumber contains lariciresinol, pinoresinol, and secoisolariciresinol.
Studies have shown that these so-called lignans are linked to reduced risk of serious illnesses such as cardiovascular disease.
4. Relieves Bad Breath
The phytochemicals in cucumber can kill the bacteria in your mouth that cause bad breath.
Hold a slice of cucumber against the roof of your mouth for around a minute and you will feel immediately refreshed!
5. Helps to Recover from That Nasty Hangover
The water content, natural sugar, B vitamins and electrolytes in cucumber will all help you in getting rid of, or even preventing, that unwelcome hangover.
Eat one or two cucumbers before going to bed or in the morning when you wake up, and you’ll be surprised how effective it can be. Or even better, don’t drink too much!
6. Helps with Weight Loss and Digestion
Cucumber is a great addition to your diet, especially for people who are looking to lose weight, because of its low calorie and high water content.
In addition, the dietary fiber and high water content in cucumbers are effective in helping the body to get rid of toxins from the digestive system.
7. Controls Cholesterol, Blood Pressure and Blood Sugar Levels
The juice of cucumber contains a hormone needed by the cells of the pancreas to produce insulin. According to research, a compound called sterols may help to reduce cholesterol levels.
The magnesium, potassium and fiber in cucumbers also have a positive effect on regulating blood pressure.
8. Good for Bones
Cucumber is a great source of silica, especially in the skin, perhaps the most abundant and potent mineral to be found in the human body.
Silica helps strengthening the bones in our bodies. The calcium and B vitamins in cucumber also promote good bone health.
