Fucoxanthin was observed to suppress the inflammatory response <i>in vitro</i> by reducing the levels of inflammatory markers such as PTGS2, iNOS, and TNF-α. Network pharmacology analysis revealed that fucoxanthin could potentially inhibit ferroptosis through 10 targets, including PTGS2.

Therefore, we aimed to analyze the characteristics and trends of whole-grain consumption in China to contribute to the development of a healthy Chinese population. We searched for important policies, standards, and dietary recommendations related to whole grains through the official websites of the China State Council and its affiliated ministries. Official and public databases, such as the National Bureau of Statistics and the China Health and Nutrition Survey (CHNS), were utilized to obtain data on whole grains and different foods. This approach was employed to gain insight into changes in whole-grain intake levels and dietary structure. Since 2010, the development of whole grains in China has received significant attention. Supportive policies have been continuously introduced on both the supply and demand sides. Numerous whole-grain standards have been developed, and terms and definitions related to whole grains have been preliminarily defined. The consumption of whole grains has fluctuated among Chinese residents since 2000, with a downward trend from 2000 to 2009, followed by an upward trend from 2009 to 2018. However, despite this increasing trend, the whole-grain intake of 80% of the adult residents was still lower than the minimum recommended dietary intake (50[Formula: see text]g/day). Furthermore, the dietary structure of Chinese residents has undergone a significant transformation, characterized by high consumption of high-fat foods, excessive consumption of meat, low intake of dietary fiber, and insufficient consumption of whole grains.

Despite its high prevalence, accounting for 60-70% of all dementia cases, there remains an absence of curative therapeutics. Microglia (MG), the resident immune cells of the CNS, exhibit a bifurcated role in AD pathogenesis. Functioning in a neuroprotective capacity, MGs express scavenger receptors, facilitating the clearance of [Formula: see text]-amyloid protein (A[Formula: see text]) and cellular debris. Conversely, aberrant activation of MGs can lead to the secretion of pro-inflammatory cytokines, thereby propagating neuroinflammatory responses that are detrimental to neuronal integrity. The dynamics of MG activation and the ensuing neuroinflammation are pivotal in the evolution of AD.

Over the past triennium, CM has garnered considerable research attention for its multifaceted approaches to AD, including the regulation of MG polarization.
