5. Aid Digestion
Onions, especially red onions are an amazing source of dietary fiber. If you suffer from digestion problems, consider increasing the amounts of onions you consume during each day or even each meal. Red onions have the right type and amount of fiber to keep you regular and promote proper digestion at the same time. Red onions have high concentrations of oligofructose, which is a soluble fiber.
This same compound also promotes the growth of good bacteria in the intestine which will help battle any bad bacteria that enters your system. Oligofructose has also been used for years to help treat certain forms of diarrhea and even to help prevent traveler’s diarrhea. Another bonus of eating red onions is that they contain phytochemicals that are effective in the fight against free radicals that cause certain types of stomach and throat ulcers.
