Before you head out to the gym, consider packing a cucumber in your gym bag. While it may seem a little strange, they make a great post-workout snack. This is due to their high water and electrolyte content. You could even add a few slices to your water bottle, helping you recover from workouts even faster.

Remember, water is essential in how our bodies operate and plays a vital role [2]. Additionally, staying properly hydrated can help keep you regular [3] and prevent constipation since they contain fiber.

Lower Blood Sugar Levels

Studies have shown that eating more cucumbers could help bring down blood sugar levels which can benefit our bodies in a variety of ways, including the prevention of diabetes, a condition that 12-14% of US adults have [4].

In one study conducted on animals, different plants effect on blood sugar levels were examined, including cucumbers. The study showed cucumbers were able to effectively decrease and regulate blood sugar levels [5].


Another great benefit of cucumbers is that they are packed with antioxidants6. Vitamin C, beta-carotene, manganese, flavonoids, triterpenes, and lignans all help to remove free radicals and keep your system in tip-top shape [7].

Vitamin C, in particular, is an essential part of a healthy diet. Not only does its antioxidant properties help fight chronic disease and cancer, but it can give a big boost to your immune system.

Many of the antioxidants also reduce inflammation throughout the body. Too much inflammation throughout the body can lead to serious health conditions like cardiovascular disease, diabetes, and arthritis [8].

Skin Health

Everyone has seen the stock images of the couple at a spa, relaxing in peace, with cucumbers slices laid over their eyes. What you may not have realized is that cucumbers actually have a host of benefits for your skin’s health.

The natural anti-inflammatory properties of cucumbers make them an effective and organic way to reduce inflammation on your skin’s surface. This includes things like acne, morning puffiness, and even sunburns.

High vegetable intake is an essential part of a healthy complexion. Their nutrient-dense nature and healing properties help bring out the best in your skin.

Heart Health

Fruits and vegetables play a vital role in keeping your heart healthy, and cucumbers are no exception. There is an abundance of studies linking cucumber consumption and low blood pressure.

Cucumbers help to reduce hypertension (high blood pressure) by widening the blood vessels. Long-term hypertension is one of the leading causes of heart failure, strokes, kidney disease, and dementia, so keeping it in check it vitally important.

While they don’t have as much potassium as bananas, a single cucumber can contribute to 4% of your daily potassium intake.

A healthy amount of potassium can reduce your chance of developing cardiovascular disease [9]. Potassium helps keep the sodium in our bodies in check—too much sodium plays a big part in leading to high blood pressure.

Bone Health

Another important vitamin in cucumbers is Vitamin K. Vitamin K is a primary aspect of healthy bones, and one cup of unpeeled cucumbers contains 19% of your daily intake.

Vitamin K is used by your body during bone development, particularly in women. Individuals who have a lower Vitamin K intake will also have a decreased bone density, increasing your chances of a bone fracture. Bone health is important for just about everyone, but especially as you age. Both men and women have increased odds of bone fractures as they age.

Increasing your Vitamin K intake through veggies like cucumbers is a great way to encourage bone strength.
