Cucumbers: Health Benefits and Side Effects (Update)

Here’s what you need to know about cucumbers, including their health benefits and side effects.

Are you curious about the humble cucumber?

I’ve researched this refreshing fruit (yes, it’s a fruit!) and am excited to share cucumbers’ health benefits and possible side effects.

What Are Cucumbers?

Cucumbers (Cucumis sativus) are part of the Cucurbitaceae family, including pumpkins, watermelons, cantaloupe, and squash. It’s fascinating to see how many fruits and veggies share this family! Cucumis originated in southern Asia and northern parts of Southeast Asia.

Did you know that cucumbers have unique names in different languages? In Afrikaans, they’re called “komkommer,” while in IsiZulu, they’re known as “ikhukhamba.”

Understanding the Cucumber Plant

I’ve observed that cucumber plants are pretty impressive! They grow as trailing vines that cover large ground areas unless they have a trellis to climb.

Cucumbers have large, hairy, dark green leaves that are semi-triangular. They grow a strong taproot that reaches about one meter deep. However, I’ve learned that the most beneficial roots are usually in the top 30 cm of soil.

Cucumber plants have both male and female yellow flowers. The female flowers show up after the male ones. They have swollen ovaries at the base. These ovaries later turn into cylindrical-shaped fruit. For every female flower, about ten male flowers will bloom!

Cucumber Varieties: More Than You Might Think

In my research, I’ve found that cucumbers grow as either vines or bushes.

There are two main varieties:

• English/Dutch cucumbers (used in salads)
• Beta Alpha cucumbers (used to make gherkins)

The English cucumber usually reaches 25-30cm long. In contrast, the Beta Alpha cucumber grows only 12-15cm.

How We Use Cucumbers for Health Benefits

I love cucumbers’ versatility!

The English variety is excellent for salads. It has a lot of water and a soft skin. Fresh cucumbers taste great, but I often peel them. Their skin can be a bit bitter and rough.

Cucumbers stand out because they are full of nutrients and low in calories, fat, cholesterol, and sodium.

They act as diuretics, helping to clean the digestive system.

They also break down uric acid. This makes them helpful for those with arthritis.

Cucumber Types: Fruits or Vegetables?

Did you know? Cucumbers are fruits! We often see them as vegetables because they taste savoury.

I categorize them into two main groups:

Slicing Cucumbers

These are the ones I enjoy eating raw in salads, sandwiches, or even at spas. Some varieties include:

• Hot House Cucumbers: These burpless cucumbers grow elongated with fewer seeds. They have crisp flesh and thin skin and are typically wrapped in plastic to retain moisture.
• Armenian or Snake Cucumbers: Long and twisted with thin, dark green skin, some seeds, and a mild taste with hints of cantaloupe. I’ve found they’re primarily used for pickling.
• Lemon Cucumbers: Round or oval, the size of a lemon, with yellow to gold skin when ripe.
• Persian Cucumbers: Shorter, cylindrical-shaped, crunchier, and less watery. They’re full of edible seeds with a mild, sweet taste and slight bitterness.
• Japanese Cucumbers: Dark green, narrow, with thin skin. I can eat these whole!

Pickling Cucumbers

Kirby Cucumbers are my go-to for making dill pickles. They’re crispy with thin skin and tiny seeds.

Cucumber Nutrition: Impressively Hydrating

Did you know our bodies are about 60% water? Cucumbers are amazing! They have 95% water content, which helps keep you hydrated. So, adding them to your diet is a smart move.

Here’s what cucumbers contain (per 100g):

• Energy: 52.0 kJ (12 calories)
• Protein: 0.59g
• Total Fat: 0.16g (Saturated: 0.01g)
• Cholesterol: 0.0mg
• Total Carbs: 2.16g
• Dietary Fiber: 0.7g
• Magnesium: 12.0mg
• Iron: 0.22mg

Cucumbers are packed with vitamins and minerals. They contain vitamin K1, vitamin A, potassium, and manganese. I’m impressed by this!

They’re also rich in antioxidants, including beta-carotene, vitamin C, tannins, and flavonoids. These flavonoids help reduce inflammation and protect against chronic diseases.

The antioxidants in cucumbers help remove free radicals from our bodies. Free radicals come from natural body processes and things like pollution. But having too many can cause health problems.

I’ve learned about cucurbitacin. It’s a bitter compound in cucumber skin and seeds. This compound might help with health benefits.

Cucumber Health Benefits: Why I Love Them

Hydration Champion

Cucumbers are great for preventing dehydration. They contain lots of water and essential electrolytes, making them perfect for hot days or after a workout.

Staying hydrated is key for a healthy intestine. It helps prevent constipation and kidney stones.

Digestive Support

Cucumbers contain flavonoids like kaempferol, quercetin, narcissin, and orientin. These compounds help ease digestion by reducing spasms.

Potential Benefits for Type 2 Diabetes

Cucumbers have a low glycemic index (GI), so they lack carbohydrates that could raise blood sugar. A 2016 study found that liquid cucumber extracts can help liver cells in stressed rats. They block oxidative and carbonyl stress, which may protect against issues often linked to type 2 diabetes.

More research is needed to confirm cucumber’s effects on people with type 2 diabetes. Still, these findings look promising!

Heart Health Support

I found a 2016 Iranian study interesting. It looked at how cucumber seed extract affects cardiovascular biomarkers.

The study involved 47 people with high blood lipids. They were at greater risk for atherosclerosis.

Researchers randomly assigned participants to take a daily capsule. One group received 500mg of cucumber seed extract, and the other took a placebo. After six weeks, the group that took cucumber seed extract showed lower BMI, triglycerides, and cholesterol levels.

I also learned that the cucurbitacin in cucumbers may help prevent atherosclerosis.

Anti-Inflammatory Properties

Research shows that inflammation can cause many health issues. These include heart disease, diabetes, autoimmune disorders, and depression.

A 2018 study from Mexico found that cucumber solutions boost nitric oxide levels. This compound helps the endothelium relax, improving blood flow at lower pressure.

Potential Cancer-Fighting Properties

Cucumbers are part of the Cucurbitaceae family and contain bitter-tasting nutrients called cucurbitacins.

The article by the International Journal of Health Services says these compounds might help stop cancer. They do this by preventing cancer cells from reproducing. Specifically, Cucurbitacin C shows promise as a potential anticancer agent.

Weight Management Support

I’ve found that cucumbers can help with weight management in several ways:

• They’re low in calories but nutrient-dense.
• You can eat them in large quantities without consuming excess calories.
• Their high water content promotes satiety.

Cucumber Side Effects: What to Watch For

I think cucumbers are a great and healthy food, but here are a few things to consider:

Potential Digestive Issues

Some people find specific types of cucumbers hard to digest. The cucurbitacin in “unburpless” cucumbers can trigger indigestion, bloating, and gas. Luckily, cucumbers grown in South Africa usually have low cucurbitacin levels. This means most people can eat them without worrying about side effects.

Vitamin K Considerations

Cucumbers are high in vitamin K, which is necessary for bone health and blood clotting. If you take blood thinners, watch your daily vitamin K intake.

Taking in too much vitamin K can reduce the effects of blood thinners. This might raise the risk of blood clots.

For most cucumber consumers, this is a minor concern. Moderate consumption of vitamin K-rich foods is beneficial to health.

Pesticide Awareness

The Environmental Working Group (EWG) ranks cucumbers as the 20th most contaminated food for pesticides. I always recommend washing cucumbers thoroughly before eating them. Just be careful not to overdo the washing, as you might lose fibre and many vitamins and minerals found in the skin.

My Conclusion: Cucumbers Are Good for You!

We’ve reached the end of this guide for cucumber’s health benefits and side effects.

Cucumbers are a popular fruit, even though many people consider them vegetables. They contain vitamins K1 and A, magnesium, potassium, and manganese.

They have key antioxidants that fight disease. Studies show they help with digestion, support heart health, reduce inflammation, and manage type 2 diabetes. They also have anticancer benefits.

South African farmers grow cucumbers without much pesticide exposure. Some people may have stomach issues from bitter cucumbers that contain lots of cucurbitacin, but cucumbers are healthy and are a good part of a balanced diet.
