Yes, you read that right.

You know that eating an entire box of cookies in one sitting isn’t good for you—but experts say overdoing it with certain more nutritious foods could be just as dangerous. There’s no need to ditch these foods from your diet altogether—but you’ll want to avoid taking in excessive amounts since that’s when they can start to compromise your health.

Oranges and Tomatoes
You’ve got to be careful to not overindulge with these delicious but highly acidic summer staples, says Gina Sam, M.D., M.P.H., director of the Mount Sinai Gastrointestinal Motility Center at The Mount Sinai Hospital. The increased acid intake associated with eating too many oranges or tomatoes can lead to reflux. Over an extended period of time, this can cause Barrett’s Esophagus, a disorder in which precancerous lesions form on esophageal lining. Sam suggests sticking to no more than two servings of oranges or tomatoes a day and avoiding these foods altogether if you already have symptoms of reflux.
This easy-to-prep, low-cal fish is a healthy salad or sandwich go-to. However, eating too much of it can result in dangerous mercury levels since tuna is higher in mercury than many other fish. Excessive mercury intake can lead to vision problems, impaired hearing and speech, lack of coordination, and muscle weakness. Make sure you don’t consume more than three to five cans of tuna a week, says Sam, and try swapping out tuna for lower-mercury fish like salmon, shrimp, and Pollock.
While hydration is key to good health, excessive water consumption can cause water intoxication, says Alan R. Gaby, M.D., author of the textbook Nutritional Medicine. This happens when extreme water intake dilutes the sodium in the body, resulting in an abnormally low blood sodium level, which can lead to impaired brain function and even death. How much water would you have to drink for this to be an issue? It’s typically only a problem for ultramarathoners and people who force themselves to over-drink. But to make sure you’re not consuming too much water, check your urine: If it’s always transparent, reduce your intake.
