Micro-vegetables (MV) are seedlings of larger vegetables. They can be grown quickly and are a concentrated source of micronutrients. MV are thought to have broad health benefits, including many inflammatory conditions. These include metabolic, cardiovascular, and cognitive diseases. This could have important implications for the health of an ageing UK population. Less than a third of British adults consume 5 portions of fruit and vegetables per day; this is the level that reduces risk of morbidity and mortality. Vegetables, including MV may - at least in part - exert their health effects by changing the level and type of bacteria in the mouth and gut. Despite their promise, the MV scientific literature is not yet extensive enough to support definitive health claims. It requires the addition of high-quality studies that are relevant to humans. This study will firstly investigate the anti-inflammatory effects on skeletal muscle and adipose tissue in older adults, using a proteomics approach. Second, this study will assess concentrations of circulating inflammatory markers in the sera collected from participants at baseline and at the conclusion of a 6-week period. Further, this study will describe the effects of six weeks MV consumption on cognition, and the oral and gut microbiome. As the bioactive compounds in the MV are owed to the potential beneficial effects for human health, these will be characterised in sera collected from participants.
