Consumer advice on fruit selection and nutritional value

A fruit vendor has provided guidance on identifying low-quality produce, warning consumers against purchasing discounted fruits that exhibit specific signs of spoilage. Even with significant price reductions, consumers should avoid fruit that shows visible mold, particularly around the stem or in crevices. Additionally, fruit that is excessively soft, leaking liquid, or emitting a fermented or sour odor should be avoided, as these are signs of advanced decay rather than natural ripeness.

In terms of nutritional value, guava has been identified as a highly efficient source of Vitamin C. Research indicates that guava can contain between 200mg and 400mg of Vitamin C per 100g, which is more than four times the amount found in oranges. Guava remains an affordable option in traditional markets, with prices varying based on variety and region, such as pear guava in Thai Nguyen or Hai Phong.
