Global climate change and rapid population growth put pressure on global production of food raw materials. The traditional planting industry is affected by climate, environmental and other factors and requires a significant investment of manpower, material resources and financial resources, which limits the production scale of plant foods. Using plant tissue culture technology to obtain callus for use as food resources or food supplements may be an effective way to solve this problem. Generally, plant tissue culture is considered to be an important branch of cellular agriculture, and the use of plant tissue culture technology can not only improve the contents of secondary metabolites in plant cells, but also allow for rapid cell culture and reduce the dependence of crop growth on the natural environment. While functional components obtained from plant cell culture have been widely used in the pharmaceutical, food additive and cosmetic industries, little literature has been found on the direct production of foods from cultured plant cells. In this paper, we review the process, features and food application of plant cell culture technology, and discuss the current challenges and future prospects for the production of plant foods using this technology.

The prevalence of high blood pressure is on the rise among younger individuals, and recent findings have linked exercise to changes in the diversity and configuration of gut microbiota. However, specific modifications to one's diet, such as incorporating blueberries while engaging in physical activity, can also influence this association. To explore the effects of exercise and blueberry consumption on gut bacteria, we conducted an 8-week study involving healthy and hypertensive college students. Our microbiome analysis revealed slight shifts in gut bacteria composition in response to increased physical activity, with significant changes in the diversity of the g_[Eubacterium]_eligens_group observed in hypertensive college students who regularly consumed blueberries. Although exercise and blueberry supplementation had a negligible impact on the gut microbiota diversity of healthy college students, it significantly boosted the production of butyric acid bacteria in hypertensive young adults. These results suggest that the changes in gut bacteria variety and abundance brought about by blueberries may be tied to alterations in the body composition of patients with hypertension. This study aims to reveal the impact of blueberry on the hypertensive students from a unique perspective, suggesting the impact of taking blueberry while taking exercises.
