Nutritionist warns against pairing watermelon with bread for at-risk groups

Dr Daria Rusakova highlights potential health risks of combining watermelon with bread, especially for individuals with impaired glucose tolerance and related conditions, emphasising moderation and balanced eating for better blood-sugar control.

Nutritionist Dr Daria Rusakova has warned that pairing red watermelon with bread may be unwise for some people, saying the combination can leave diners feeling bloated and may place extra strain on blood-sugar control. In comments reported by a Russian outlet, she said the fruit’s fructose content, combined with the carbohydrates in bread, can create a heavy load for those with impaired glucose tolerance.

She added that the mix may encourage gas and fermentation in the intestines, particularly when eaten in larger amounts. Her concerns also extend to people living with diabetes, insulin resistance, digestive disorders, cardiovascular disease and kidney conditions, for whom sudden rises in blood sugar or fluid balance problems may be more relevant.

The warning fits a broader nutrition picture around watermelon: Healthline has noted that eating too much of the fruit can trigger digestive discomfort, including bloating, gas and diarrhoea, partly because of its FODMAP content. It also points out that watermelon has a high glycaemic index, which means it can raise blood sugar quickly, even though its overall glycaemic load is relatively low when portions are kept sensible.

Elsewhere, gastroenterologists quoted by NDTV have said watermelon eaten straight after a heavy meal can slow digestion and contribute to a sensation of fullness, while its fructose content may ferment in the colon and cause abdominal discomfort. Healthline says people who want to avoid blood-sugar spikes can still eat watermelon in moderation and may find it easier to tolerate when it is paired with foods containing protein, fat or fibre rather than bread alone.
