2. Citrus Foods
Citrus fruit — like oranges, tangerines, grapefruits, lemons and limes — are very popular and for good reason: not only are they very flavorful on their own or when added to other foods and drinks, but they contain lots of vitamin C, which can help boost the immune system.
But there is one drawback to eating or drinking a lot of citrus: it tends to upset the bladder, and may be more problematic for people who regularly struggle with bladder-related health problems. The more acidic the fruit, the worse, which means lemon, lime and grapefruit should be kept at arm’s length until you’ve put bladder problems behind you.
