Benefits for the gut microbiome
According to the study published in 2025 by Dr. Kristina S. Petersen, Associate Professor of Nutritional Sciences at Pennsylvania State University (Penn State, USA). The study attracted 51 adults in the prediabetes stage. They were asked to eat about 57 grams of chestnuts per night for 12 weeks, with the expectation of comparing the difference compared to the group consuming 15 - 30 grams of carbohydrates. Specifically, there is an increase in beneficial bacteria such as Roseburia and Lachnospiraceae, along with a decrease in less beneficial bacteria such as Flavonifractor.
Nutritionist Morgan Pearson, MS, RD, who led the study, commented: Pteed seeds contain fiber, polyphenols and prebiotic compounds that help nourish beneficial microbiota, thereby reducing inflammation and improving digestive health. Pearson is currently working at the University of California Center for Trans fructoreous Nutrition.
However, she also emphasized that more research is needed to better understand the long-term effects of rice paper on gut health.
Good for the heart and control blood sugar
In addition to digestive benefits, chestnuts also have a positive impact on cardiovascular health. Some studies show that eating this seed regularly helps reduce bad LDL cholesterol, reduce triglycerides and help maintain good HDL cholesterol levels. Nutrients like healthy fats, potassium, vitamin B6, and antioxidants in laughing tea seeds can help reduce inflammation, improve vascular elasticity, and reduce the risk of stroke.
According to Dr. Eliseo Guallar, an epidemiologist at the Johns Hopkins School of Public Health (USA): P pointed nut is one of the nuts with the highest nutritional density, especially good for people at risk of heart disease and metabolic diseases.
Regarding the ability to regulate blood sugar, some studies have found that eating about 1/3 of a cup of laughing tea seeds per day can reduce fasting blood sugar levels, improve insulin levels and reduce insulin resistance. Although the results are not completely consistent, the positive trend is opening up many new research directions.
Can help with weight loss
Although there is not much in-depth research, initial data shows that people who eat laughing tea seeds regularly tend to eat less sugar and more fiber. This contributes to creating a feeling of fullness for a long time and supporting weight control, especially when combined with a healthy diet and regular exercise.
Nutritional value of laughing tea seeds
In a serving of about 28 grams (1 ounce), chestnuts provide about 159 calories, 6 grams of protein, 3 grams of fiber, 289 mg of potassium and a significant amount of vitamin A. This is an ideal choice for evening snacks, mixed with salad, made with pesto sauce or eaten with fruit.
