What Are Yellow Bell Peppers?

Yellow capsicum is the semi-ripe fruit of the Capsicum annuum plant, commonly called bell pepper. All capsicums start as green bell peppers and then change colors as they mature. Yellow bell peppers are the intermediate phase of the ripening process.

Yellow bell peppers are sweeter than green capsicum but tangier than red. They are also more nutritious than green peppers but not as nutrient-dense as red bell peppers.

This description applies to most bell pepper types, but there are many varieties of capsicum, and they come in many different colors.

Nutrients in Yellow Bell Peppers

Yellow bell peppers contain higher levels of nutrients than green bell peppers but less than red. The exception to this rule is in their carotenoid content. These plant compounds change form as the capsicum matures and are why the peppers change colors. Green bell peppers are the highest high in lutein. Red capsicum contains the most capsanthin, and yellow peppers offer the most violaxanthin.

Health Benefits of Yellow Bell Peppers

Yellow bell peppers contain many important vitamins, minerals, and plant compounds that doctors have found beneficial to our health. Here we present 11 health benefits that yellow capsicum can provide.

1. Reduces The Risk of Heart Disease

Bell peppers contain high amounts of vitamin C, folate, and other compounds that lower the risk of a heart attack. Vitamin C acts as a natural diuretic. Diuretics remove excess water from our system and reduce the tension within our blood vessels. Folate helps regulate levels of the amino acid homocysteine. High homocysteine levels and hypertension are two of the leading contributing factors in the development of heart disease. Beyond this, yellow bell peppers contain natural anticoagulants that can help prevent blood clots.

2. Prevents Anemia

Characterized by feelings of tiredness and fatigue, anemia affects your blood’s ability to carry oxygen. One of the leading causes of anemia is low iron levels. Yellow bell peppers contain a fair amount of iron, but more importantly, the vitamin C they offer helps the body absorb and utilize the iron.

3. Helps Maintain Eye Health

The two leading forms of vision impairment in America are cataracts and macular degeneration. A significant contributor to both of these conditions is diseases and free radical damage within the light-sensitive areas of the eye. Yellow bell pepper’s high carotenoid content fights free radical damage to the retina, protecting your vision, and their nutritional value improves your overall health.

4. Improves Digestion

Yellow capsicum delivers 2.1 grams of dietary fiber per 100-gram serving. Dietary fiber adds bulk to your stool, making it easier to pass and improving your overall digestive health. High-fiber foods also aid in preventing hemorrhoids.

5. Reduces The Risk of Diabetes

Both the vitamin C and fiber in yellow bell peppers can aid in the fight against diabetes. Researchers have found that Vitamin C helps reduce blood sugar levels in people with type 2 diabetes. Fiber slows down the absorption rate of sugars in the stomach reducing the severity of insulin spikes people experience.

6. Lowers Blood Pressure

Research indicates that vitamin C in yellow bell peppers acts as a natural diuretic and helps the body get rid of excess fluids. Eliminating surplus fluids from your system reduces the pressure within your blood cells. You could think of yellow capsicum as nature’s water pill.

7. Help With PMS

Yellow bell peppers contain a high level of vitamin B6, which helps regulate hormone production in the body. Many of the most common symptoms of premenstrual syndrome are caused by a woman’s hormones being in flux. While high amounts of B6 in yellow bell peppers won’t eliminate PMS, the evidence does indicate it help lessen its severity.

8. Boosts Immunity

One 100-gram serving of yellow bell peppers contains over three times the recommended minimum daily allowance of vitamin C. Considered a wonder nutrient by many; vitamin C is a well-established immunity booster.

9. Improves Skin Health

Yellow bell peppers promote healthy skin in two ways. Their high antioxidant content helps protect skin cells from free radical damage. As a bonus, yellow capsicum contains significant amounts of the protein compound collagen. Collagen is one of the basic building blocks of skin and promotes the growth of healthy skin cells.

10. May Help Fight Cancer

Free radical damage, especially to cell DNA, is a contributing factor in the development of cancer and many other health problems. Animal studies have shown a marked decrease in cancer development when subjects receive a diet high in antioxidants. Yellow bell peppers are rich in a variety of antioxidant compounds. You should note that doctors have not duplicated the results of the animal studies in human trials.

11. Fights Depression

Researchers have found a correlation between folate and vitamin B6 levels and depression. Several studies have found that people suffering from mild depression improved when treated with B6 and folate. Other studies found that sufferers of severe depression experienced more significant benefits from antidepressants when given in conjunction with folate and vitamin B6. Yellow bell peppers are a healthy source of both vitamin B6 and folate.
