Health Benefits and Effects of Green Bell Peppers

Key Health Benefits:

Cancer prevention, appetite stimulation, and fatigue relief

Introduction:

People in the Sichuan and Chongqing regions of China are renowned for their love of spicy food—and green peppers are an indispensable ingredient. Native to tropical Central and South America, green peppers were introduced to China over a century ago and are now widely cultivated across the country. Their vitamin C content is 7–15 times higher than that of tomatoes—the highest among all vegetables. Moreover, their distinctive aroma and flavor stimulate salivary secretion. Today, we’ll explore the specific health benefits and functions of green peppers.

Health Benefits and Functions:

Cancer Prevention

Green peppers contain 7–15 times more vitamin C than tomatoes, along with vitamin P (bioflavonoids), which enhances vitamin C absorption. Notably, vitamin C remains stable even after cooking—making green peppers an excellent dietary source of this potent antioxidant. Vitamin C effectively neutralizes harmful free radicals in the body. In addition, beta-carotene and capsaicin found in green peppers also possess antioxidant properties, helping to inhibit abnormal cellular metabolism and thereby interrupting the carcinogenic process and reducing cancer risk.

Appetite Stimulation

Green peppers promote the secretion of digestive juices and enhance appetite. This effect stems from capsaicin—a compound present in chili peppers—that stimulates the oral cavity and gastrointestinal tract. Consequently, it strengthens gastrointestinal motility, boosts digestive enzyme secretion, improves appetite, suppresses abnormal intestinal fermentation, and helps expel accumulated gas from the digestive tract.

Fatigue Relief

Green peppers play a significant role in alleviating fatigue. Furthermore, their vitamin P content facilitates better absorption of vitamin C—even when cooked—ensuring minimal loss of this vital nutrient.

Nutritional Value:

Green peppers have high water content and low caloric value; however, as they ripen, their water content decreases while calorie density increases. Levels of vitamins A and C rise progressively with maturity. On average, their vitamin C content is approximately 3.5 times higher than that of tomatoes—comparable to strawberries and lemons—and ranks highest among vegetables. Rich in vitamin C, beta-carotene, and other antioxidants, green peppers help eliminate harmful free radicals in the body. For pregnant women, regular consumption may bolster immune function and reduce risks of cancer and other chronic diseases. Frequent intake of green peppers may also help prevent gallstones: their abundant vitamin C promotes conversion of excess cholesterol into bile acids, thereby inhibiting gallstone formation. Green peppers aid in preventing scurvy and offer supportive benefits for gingival bleeding, anemia, and vascular fragility. They further help prevent microvascular hemorrhage—including gingival, retinal, and cerebral hemorrhages. Additionally, rich in B vitamins, vitamin C, and beta-carotene, green peppers support digestion and accelerate fat metabolism.

Precautions:

Recommended for:

Generally suitable for all population groups.

Not recommended for:

Individuals with eye disorders, esophagitis, gastroenteritis, gastric ulcers, or hemorrhoids should limit or avoid consumption. Those with excessive internal heat ("fire syndrome"), yin deficiency with hyperactive fire, hypertension, pulmonary tuberculosis, or facial paralysis should also exercise caution.
