[1]"Yam tuber is rich in nutrients and bioactive compounds, such as starch, protein, non-starch polysaccharides, steroid saponin, allantoin, and phenolic compounds. The most important health benefits include antioxidant activity, anti-inflammatory activity, gastrointestinal protection, gut microbiota regulation, cardiac diseases treatment, hypoglycemic activity, anti-tumor activity, and estrogen-like effect. We also summarize the applications of yam tuber in foods and medicine. Finally, the review indicates that better utilization of yam tuber is hindered by poor variety protection, limited research on its pharmacological activities, browning phenomenon, and some safety concerns."

In the context of the fast-paced modern lifestyle, a significant proportion of the population experiences a range of digestive issues, including weak spleen and stomach function and indigestion. Due to its mild nature and high dietary fibre content, yam is effective at regulating the functions of the spleen and stomach, as well as promoting the digestion and absorption of food.

Additionally, yam contains a distinctive mucin protein that safeguards the gastric mucosa and mitigates excessive stimulation by gastric acid. Consequently, yam is frequently recommended as a daily nourishing ingredient for individuals with gastritis or gastric ulcers.

Recent studies have demonstrated that yam is a rich source of immune-enhancing nutrients, including polysaccharides, amino acids, and vitamins. These nutrients have been shown to promote the production and activation of white blood cells, thereby enhancing the body's ability to combat external pathogens. For those with weakened immune systems and a proclivity for illness, yam represents an optimal dietary choice for immune-regulating properties that can be sustained over time to fortify the body and enhance resilience.

Furthermore, the multitude of nutrients present in yam can enhance the body's energy metabolism, alleviate fatigue and facilitate the restoration of stamina. Consequently, yam can be considered an efficacious tonic for individuals experiencing prolonged fatigue due to occupational demands.
