Raspberries are rich in vitamins, antioxidants, and fiber; however, in some cases, this berry can cause serious health problems. A dietitian warned about this, urging people to consider their individual health conditions. According to the specialist, particular caution should be exercised by individuals prone to allergic reactions. Raspberries contain substances that can trigger cross-allergies. As a result, rashes, itching, and swelling of the lips, tongue, and throat may occur. In severe cases, an anaphylactic reaction may develop, which poses a life-threatening risk without timely medical assistance. People with gastrointestinal diseases are also advised not to overindulge in raspberries. The organic acids present in the berry can irritate the stomach lining, so it should be consumed with caution in cases of gastritis, peptic ulcers, or inflammatory bowel diseases. Additionally, consultation with a doctor is necessary for individuals with kidney diseases or urolithiasis. In some cases, excessive consumption of raspberries may worsen the condition. For most people, raspberries remain a beneficial berry, but those with allergies, gastrointestinal diseases, or kidney issues should include them in their diet cautiously and, if necessary, after consulting a specialist.
