Not lemons or oranges. Doctor-fitness enthusiast calls common fruit 'king' of vitamin C

While oranges have long been celebrated as the ultimate source of vitamin C, Dr. Anshul Sadhale, a physician and fitness expert, argues otherwise. In a post on X, he pointed out that guavas contain more than four times the vitamin C found in oranges, making them an exceptional fruit for overall health. According to Dr. Sadhale, a single cup of guava delivers around 370 mg of vitamin C—an impressive amount that fuels tissue repair, boosts immune strength, and supports collagen production, all of which are crucial for recovery after intense workouts.

The Fiber Advantage: Fullness and Control

Dr. Sadhale further explained that guavas are rich in dietary fiber, an essential nutrient for individuals aiming to lose weight or manage appetite. The high fiber content slows down the digestive process, ensuring stable blood sugar levels and prolonged satiety. This helps reduce hunger pangs, making it easier to stick to a healthy eating plan. Guavas also have a low glycemic index, meaning they release energy gradually instead of causing sudden spikes and crashes. This steady energy flow enhances insulin sensitivity, allowing the body to utilize nutrients more efficiently and store them in muscle tissue rather than fat cells.

You think oranges are the king of Vitamin C?

Not even close.

There’s a fruit with over 4x the amount that’s a secret weapon for appetite control and recovery.

A Complete Nutritional Package

When compared to other fruits, guavas offer an unmatched nutritional profile. Dr. Sadhale described them as a “nutritional Swiss Army knife.” While bananas are known for their potassium content, guavas go a step further by combining potassium with high levels of vitamin C, antioxidants such as lycopene, and vitamin A. This blend delivers greater nutritional value with fewer calories, making guavas an intelligent choice for those pursuing a balanced diet.

Scientific Insights: The Healthline Findings

According to a Healthline report, several studies conducted between 2020 and 2022 found that guava leaf extract helped regulate blood sugar levels, improve insulin resistance, and enhance long-term glucose control. Researchers have also noted guava’s potential to support cardiovascular health. The fruit’s abundance of antioxidants and vitamins, especially in its leaves, helps protect the heart from oxidative stress.

Heart and Weight Benefits

Additionally, the potassium and soluble fiber in guavas contribute to better heart function by reducing high blood pressure and maintaining cholesterol balance. Studies indicate that guava leaf extract may lower “bad” LDL cholesterol and raise “good” HDL cholesterol, thereby reducing the risk of heart disease and stroke. For weight management, guavas are a perfect ally—each fruit provides about 12% of the daily recommended fiber intake, offering a filling yet low-calorie snack option that supports both health and fitness goals.
