The Environmental Working Group (EWG) produces a list each year of fruits and vegetables with the highest levels of pesticide residue, known as the Dirty Dozen. Cherry tomatoes are high on the list of produce that the EWG suggests that you buy in the organic version to ensure a lower risk of pesticide exposure. If you can not afford organic, do not fret; the nutritional benefit of eating conventionally grown (non-organic) produce far outweighs the risk of not eating produce at all.
Beta-blockers, a type of medication most commonly prescribed for heart disease, can cause potassium levels to increase in the blood. High potassium foods such as tomatoes should be consumed in moderation when taking beta-blockers.
Consuming too much potassium can be harmful for those whose kidneys are not fully functional. If your kidneys are unable to remove excess potassium from the blood, it could be fatal.
Those with gastro-esophageal reflux disease (GERD) may experience an increase in symptoms such as heartburn and regurgitation when consuming highly acidic foods such as tomatoes, however individual reactions vary.
It is the total diet or overall eating pattern that is most important in disease prevention and achieving good health. It is best to eat a diet with variety than to concentrate on individual foods as the key to good health.
