Can I eat grapes if my blood sugar is high during chemotherapy?

Patients with high blood sugar undergoing chemotherapy can consume small amounts of grapes, but should carefully control the intake. Grapes contain abundant nutrients, such as flavonoids and resveratrol, which have antioxidant, anti-inflammatory, and cancer-preventive properties. However, grapes also contain high levels of sugar, primarily fructose and glucose, which can rapidly elevate blood sugar levels. Excessive grape consumption may cause fluctuations in blood sugar and negatively affect disease management in patients with hyperglycemia. Therefore, it is recommended that patients with high blood sugar who wish to eat grapes during chemotherapy consume only small quantities and closely monitor their blood sugar levels. Additionally, to avoid discomfort caused by the cold temperature of grapes, they can be soaked in warm water before consumption. If needed, patients should consult their physician or a nutritionist to develop a personalized dietary plan.
