In general, eating too much yam can have adverse effects, so it is important to consume it in moderation in daily life.

Yam, as a common food ingredient, has functions such as strengthening the spleen and stomach, nourishing the kidneys, and benefiting the lungs to relieve coughing. It is a highly nutritious food. Yams contain starch, protein, vitamins, and various minerals, offering numerous health benefits such as enhancing immunity and improving the digestive system. However, as with any food, yam should be consumed in moderation.

Yam contains abundant dietary fiber, and moderate consumption can promote intestinal motility and help prevent constipation. However, excessive intake may cause gastrointestinal discomfort, such as bloating and diarrhea. Especially for individuals with spleen and stomach deficiency-cold, excessive yam consumption may worsen symptoms. Additionally, yam contains a certain amount of starch; excessive consumption increases caloric intake, which may lead to weight gain or fluctuations in blood sugar levels.

In daily diet, it is recommended to properly combine foods, control portion sizes, and avoid excessive consumption of any single food item, which helps maintain overall health.
