Nutrition experts say that fermented or pickled foods often contain high levels of sodium (salt). When consuming too much sodium, the body tends to retain water, while creating pressure on the kidneys during filtration and excretion. In the long run, this can affect people with pre-existing kidney disease or high blood pressure.
In addition, sour bamboo shoots, if not processed thoroughly, may contain natural compounds such as cyanogenic glycosides, which need to be treated properly to remove toxins. Some ready-made sour bamboo shoot products may also be supplemented with salt or preservatives, increasing the risk of electrolyte imbalance if eaten a lot.
Nutrition experts also note that eating a lot of sour and salty foods can cause the body to increase water secretion through the kidneys, leading to a feeling of more thirst and mild dehydration, especially in hot and humid weather conditions.
However, experts do not recommend completely removing sour bamboo shoots from the diet. Instead, they should be used in moderation, combined with a variety of fresh foods and drink enough water every day to maintain balance for the body.
Experts emphasize that the problem is not in the dish itself, but in the processing method and frequency of use in daily meals.
