Recently came upon an article that said you should eat fruits (regardless of the type) before a meal, so that you can absorb all its healthy nutrients before the less nutritious spaghetti or rice. If we eat it last, the fruit may ferment before entering our stomach/intestines due to the bottleneck of food that entered a couple of minutes earlier. The fructose may then turn into gas to contribute to our belly bloat.
Some of you may question this piece of advice, saying that oranges are acidic and will burn through our stomach lining. However, our digestive tracts can neutralize most acids (unless it’s sulfuric acid) before they enter our stomach.
