Guava is the highest source of ascorbic acid

Ascorbic acid, also known as vitamin C, is an essential nutrient that plays a crucial role in various bodily functions. It is a powerful antioxidant that helps protect cells from damage, supports the immune system, aids in collagen production, and enhances iron absorption. While all the options mentioned (apple, beans, carrot, and guava) contain ascorbic acid, guava is the highest source among them.

Guava's ascorbic acid content

Guava is a tropical fruit that is widely known for its high vitamin C content. In fact, guava contains more ascorbic acid than any other commonly consumed fruit. Here are some key facts about guava's ascorbic acid content:

1. High concentration: Guava contains approximately 228 mg of ascorbic acid per 100 grams of fruit. This is significantly higher than the ascorbic acid content in other fruits such as oranges (53 mg/100g) and strawberries (59 mg/100g).

2. Recommended daily intake: The recommended daily intake of vitamin C for adults is around 75-90 mg. Consuming just 100 grams of guava can provide more than double this amount, making it an excellent natural source of ascorbic acid.

3. Raw vs. processed: While raw guava is already a great source of ascorbic acid, the vitamin C content can decrease when the fruit is processed or cooked. Therefore, consuming raw guava or freshly squeezed guava juice is the best way to maximize your ascorbic acid intake.

4. Other nutrients: Guava is not only rich in ascorbic acid but also contains other essential nutrients such as dietary fiber, potassium, and vitamin A. These nutrients work together to support overall health and well-being.

The importance of ascorbic acid

Ascorbic acid is vital for maintaining good health and preventing various diseases. Here are some key reasons why consuming an adequate amount of ascorbic acid is important:

1. Immune system support: Vitamin C is known for its immune-boosting properties. It helps stimulate the production of white blood cells, which are important for fighting off infections and illnesses.

2. Antioxidant activity: Ascorbic acid acts as a powerful antioxidant, neutralizing harmful free radicals in the body. This can help reduce the risk of chronic diseases, such as heart disease and certain types of cancer.

3. Collagen production: Vitamin C plays a crucial role in the synthesis of collagen, a protein that supports the structure and health of various tissues in the body, including the skin, bones, and blood vessels.

4. Iron absorption: Ascorbic acid enhances the absorption of non-heme iron from plant-based sources. This is particularly important for individuals following a vegetarian or vegan diet, as non-heme iron is less easily absorbed than heme iron from animal sources.

In conclusion, while all the options mentioned contain ascorbic acid, guava is the highest source among them. Adding guava to your diet can help meet your daily vitamin C requirements and provide numerous health benefits. Remember to consume it in its raw form or as freshly squeezed juice to maximize
