Introduction

In this article, you can find a detailed description of the differences between eggplant and cucumber.

What's The Actual Difference?

Eggplant belongs to the Solanum genus, and cucumber belongs to the Cucumis genus. Eggplant is a dark purple or brownish-purple color, whereas regular cucumbers have green stripes on darker green skin.

Cucumbers are commonly green but can also be white, yellow, or orange. Cucumbers' flavor is all about their texture and water content; they are sweet and plumpy. Eggplant has a tender, mild, and sweet flavor.

Glycemic Index

Overall, vegetables are considered low glycemic index foods. However, the glycemic index of cucumber is a bit lower than that of eggplant.

Cucumber has a glycemic index of 21 and a glycemic load of 1.5.

Eggplant has a GI of 30 and a glycemic load of 1. This means that consumption of both plants will not raise your blood sugar levels.

Health Impact

Cardiovascular Health

Cucurbitacins are compounds found in cucumbers, which have both toxic and beneficial health effects. One of the advantages is that they can prevent or slow the progression of atherosclerosis by modifying lipoproteins. According to one study [1], cucumber lowers systolic and diastolic blood pressure in older people. The potential mechanism is due to its diuretic effect, which reduces circulating fluid in the bloodstream, reducing the workload on the heart.

For 30 days, animals were fed either raw or grilled eggplant in one study [2]. Both types improved heart function and reduced the severity of heart attacks. However, more research is needed to determine how eggplants affect human heart health.

Cancer

Research shows that cucurbitacins inhibit tumor cell growth and signaling pathways and cause cancer cells to die. Cucurbitacins have antitumor activity against lung, pancreatic, colon, breast, and cervical cancers [3]. Triterpenes and lignans isolated from cucumber have shown anticancer activity against liver cancer by inducing cancer cell death [4].

Solasodine rhamnosyl glycosides (SRGs) are compounds found in nightshade plants such as eggplant. SRGs have been shown in animal studies [5] to cause cancer cell death and may also help reduce the recurrence of certain types of cancer.

Diabetes

Eggplants are high in phenolic compounds, which according to research, may regulate carbohydrate metabolism in the body. This mechanism gives insulin more time to digest the carbohydrates, mostly from refined foods with little fiber or vitamin content [6].

Another study found that polyphenols can help lower blood sugar by reducing sugar absorption and increasing insulin secretion. Eating eggplant inhibits the enzyme that converts starch into blood sugar, making it one of the most effective foods for diabetes prevention [7].

Skin Health

Keeping your skin hydrated helps to improve elasticity and firmness. Lack of hydration can cause your skin to appear dry and flaky and more prone to fine lines and wrinkles. Cucumbers are high in polysaccharides, which can help to keep the skin elastic and healthy. Cucumbers are mostly water; in fact, they are 96 percent water. Cucumbers' high water content is a crucial benefit because it allows them to provide superior hydration to the skin [8].

Other Health Benefits

Cucumbers are high in water (96%), which may help to keep you hydrated. Dehydration is a significant risk factor for constipation because it can disrupt your water balance and make stool passage difficult. Staying hydrated can help with stool consistency, constipation prevention, and regularity. Cucumbers also contain fiber, which also aids in the regulation of bowel movements [9].

Animal studies [10] suggest that nasunin, an anthocyanin found in eggplant skin, may help protect brain cell membranes from free radical damage.

Anthocyanins also help to reduce neuroinflammation and increase blood flow to the brain. This may aid in preventing memory loss and other aspects of aging-related mental decline [11].

Side Effects

Allergy

Cucurbits have been linked to oral allergy syndrome (itching, burning, redness, and swelling of the lips), nausea, diarrhea, asthma, rhinitis, watery eyes, and contact urticaria. Eggplant belongs to a family of plants known as nightshades. People may more likely develop an eggplant allergy if allergic to other nightshades, including tomatoes, potatoes, or peppers.

Cucumbers and eggplants contain salicylate, so people who are allergic to Aspirin should avoid cucumbers, apples, almonds, oranges, berries, tomatoes, and other foods [12].
