An adequate vitamin C intake helps keep healthy skin, since it favors wound healing, reduces the appearance of wrinkles and protects against skin damages caused by UV radiation.

The recommended daily vitamin C intake for adults is 75-90 milligrams. A medium orange contains approximately 70 milligrams of vitamin C, which makes it an excellent source to meet daily needs.

Fiber: Promoting Gut Health and Digestion

There are two types of fiber: soluble and insoluble. Soluble fiber dissolves in water and forms a gelatinous substance in the digestive tract. It is found in foods such as oats, legumes and fruits. The insoluble fiber, on the other hand, is not dissolved in water and adds volume to the feces, facilitating intestinal transit. Whole grains, nuts and vegetables are excellent sources of insoluble fiber.

• Fiber helps regulate intestinal movements by adding volume to feces, facilitating their evacuation.
• It favors the growth of beneficial bacteria in the intestine, contributing to a healthy intestinal microbiome.
• Fiber can help control blood sugar levels by slowing sugar absorption in blood torrent.
