In a recent systematic review published in the journal Advances in Bamboo Science, researchers assessed human consumption studies and in vitro investigations using human cell models, alongside laboratory studies relevant to food processing, to evaluate the health effects of consuming bamboo shoots and derived products.

Based on available evidence, they concluded that, while human data remain limited, properly prepared bamboo products may offer several health benefits, including improved digestive, antioxidant, and metabolic outcomes. However, each reported benefit is supported by a small number of individual studies rather than a broad clinical evidence base.

Bamboo as an Emerging Functional Food

Bamboo is a fast-growing, highly versatile plant belonging to the grass family, with more than 1,250 species worldwide. Although found across most continents, bamboo is most abundant in Asia, accounting for around 80% of global coverage.

Its rapid growth, high biomass yield, and adaptability have made it valuable not only for construction and environmental applications but also as a food source. Bamboo leaves and shoots are commonly consumed, particularly in Asian cuisines. They are nutritionally attractive due to their high protein content, moderate fiber levels, low fat content, and presence of essential amino acids and minerals such as potassium and selenium.

Previous research suggests that compounds derived from bamboo may have several health benefits. However, bamboo consumption also carries risks, as some species release cyanide from cyanogenic glucosides if not properly processed, posing serious health hazards. Appropriate preparation, such as boiling, is therefore essential to reduce potential toxicity.

Scope and Design of the Systematic Review

Despite growing interest in bamboo as a functional food, it had not previously been systematically evaluated. Researchers searched Medline (via PubMed) and Web of Science, assessing study quality using standardized risk-of-bias tools. The systematic search identified 1,052 potentially relevant records. After title and abstract screening, 19 full-text articles were evaluated; 16 met the inclusion criteria.

These comprised four human studies, four in vitro studies using human cell lines, and eight laboratory-based studies examining bamboo components with relevance to nutrition and food processing. All but one were set in Asia. The overall methodological quality of the in vivo human studies, assessed using the Newcastle–Ottawa Scale, was moderate.

Evidence From Human Consumption Studies

The four human studies involved a total of 4,934 participants and examined diverse health outcomes. One large cross-sectional study in schoolchildren reported a high prevalence of goiter (31%) despite adequate iodine intake, suggesting a possible association with frequent consumption of bamboo shoots rather than established causality.

Supportive evidence from an experimental rat component within the same study showed altered thyroid structure and reduced thyroid hormone levels following bamboo shoot intake, reinforcing concerns about potential goitrogenic effects.

In contrast, other human studies reported beneficial effects. A randomized trial found that flavonoid-rich antioxidants from bamboo leaves reduced internal exposure to glycidamide and acrylamide by altering toxicokinetics and increasing urinary excretion of related biomarkers, with sex-specific differences observed.

A study in people with diabetes showed that cookies fortified with bamboo shoots significantly lowered postprandial blood glucose levels in a dose-dependent manner.

Another small dietary intervention in healthy women demonstrated improvements in lipid profiles, including reductions in total cholesterol and low-density lipoprotein (LDL) cholesterol, along with increased bowel movement frequency and increased stool volume, indicating improved bowel function.

In Vitro Findings Using Human Cell Models

Four studies investigated bamboo extracts using human cell models. These consistently showed antioxidant and anti-inflammatory properties, including reduced reactive oxygen species production, inhibition of inflammatory markers, improved cell viability, and low cellular toxicity.

Bamboo leaf and shoot extracts also reduced oxidative stress and apoptosis under high-glucose conditions, supporting a potential but not yet clinically established protective role against metabolic and inflammatory damage.

One study assessing heavy metal content found elevated lead levels in some bamboo shoots; however, simulated intestinal digestion did not induce toxicity in intestinal cells, suggesting that conventional risk assessments may overestimate health risks when bioaccessibility is not considered.

Laboratory Studies Relevant to Nutrition and Food Processing

Eight studies explored bamboo-derived ingredients for nutritional and technological applications. These demonstrated potent antioxidant activity and prebiotic-like effects in laboratory-based studies, through stimulation of beneficial gut bacteria and the production of short-chain fatty acids, but lacked direct evidence from human gut studies.

Bamboo extracts reduced harmful compounds such as acrylamide and furan during food processing without compromising sensory quality. Other studies highlighted the high nutritional value of bamboo shoots, including fiber, protein, vitamins, and minerals, and showed that processing methods and harvest stage influence nutrient composition and functional properties.

Overall Interpretation and Research Gaps

Overall, the findings suggest that properly prepared bamboo products may offer multiple health benefits, including improved glycemic control, lipid profiles, bowel function, antioxidant capacity, and reduced exposure to food-processing toxins. Importantly, these outcomes are derived from distinct, mostly small studies, and should be interpreted individually rather than as a unified body of clinical evidence. These effects are likely linked to bamboo’s rich content of dietary fiber, bioactive compounds, and micronutrients.

However, concerns remain regarding potential goitrogenic effects, particularly with frequent consumption of inadequately processed bamboo shoots. Importantly, appropriate preparation methods such as boiling are thought to substantially reduce cyanogenic compounds, although human evidence remains limited.

The main limitations include the limited number of human studies, substantial heterogeneity in outcomes and study designs, and a lack of high-quality trials, which precluded meta-analysis. Despite these constraints, the evidence supports bamboo’s promise as a sustainable, nutrient-rich food. Further well-designed human intervention studies are needed before firm dietary recommendations can be made.
