Some experts encourage people to eat up to two oranges per day for the fruit's beneficial phytochemicals, flavenoids and vitamin C content. There is some debate, however, over whether or not the benefits of orange consumption outweigh the potential drawbacks.
People who suffer from gastro-esophageal reflux disease (GERD) or chronic heartburn might experience heightened symptoms with orange consumption. This is because oranges are highly acidic fruits and may contribute to increased acidity in the gastrointestinal system. They can also create lesions on the esophagus.
Additionally, the high potassium content in oranges can cause problems for patients who take beta-blockers, which are a group of medications used to treat heart disease. The potassium in oranges can also negatively affect people who suffer from kidney failure.
Oranges offer a number of health benefits, including improvements to the immune system, memory, sleep quality, fat absorption and energy levels. They have also proven to help reduce inflammation. The best way to consume oranges is in moderation, pairing them with other healthy fruits, vegetables, proteins and whole grains to ensure a balanced diet.
People who suffer from GERD, heart disease or kidney problems should consult a physician about consumption of oranges to avoid putting their health in jeopardy. It is also important to pay attention to the body's physical response to oranges. Severe heartburn, for example, might indicate the acidity level in oranges is too high for the body to tolerate.
