Specifically, the gut microbiota affects skeletal homeostasis through changes in host metabolism, the immune system, hormone secretion, and the gut-brain axis. The major role on gut-bone axis is due to short-chain fatty acids (SCFAs). They have the ability to influence regulatory T-cell (Tregs) development and activate bone metabolism through the action of Wnt10. SCFA production may be a mechanism by which the microbial community, by increasing the serum level of insulin-like growth factor 1 (IGF-1), leads to the growth and regulation of bone homeostasis. A specific SCFA, butyrate, diffuses into the bone marrow where it expands Tregs. The Tregs induce production of the Wnt ligand Wnt10b by CD8+ T cells, leading to activation of Wnt signaling and stimulation of bone formation. At the hormonal level, the effect of the gut microbiota on bone homeostasis is expressed through the biphasic action of serotonin. Some microbiota, such as spore-forming microbes, regulate the level of serotonin in the gut, serum, and feces. Another group of bacterial species (Lactococcus, Mucispirillum, Lactobacillus, and Bifidobacterium) can increase the level of peripheral/vascular leptin, which in turn manages bone homeostasis through the action of brain serotonin.</p>","PeriodicalId":8269,"journal":{"name":"Annals of Nutrition and Metabolism","volume":" ","pages":"1-10"},"PeriodicalIF":3.2,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143027876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eating habits start to be shaped early in life, making the introduction of solid foods a critical period. Given the high prevalence of obesity, its long-term health consequences, and social implications, prevention is crucial. This narrative review aimed to identify factors related to the introduction of solid foods that influence obesity and suggest feeding strategies to prevent it. Tracking studies indicate that overweight and obesity during childhood often persist into adulthood, with associated complications such as hyperglycemia, dyslipidemia, hypertension, and nonalcoholic fatty liver disease. Complementary feeding involves introducing solid foods besides breast milk or formula. The timing and content of complementary feeding are crucial in influencing obesity risk. Introduction of solid foods before 4 months is associated with higher BMI in childhood. The method of introducing complementary feeding, such as baby-led weaning, has been proposed to predict later obesity risk, though findings are currently inconclusive. Parental feeding practices and socioeconomic factors significantly influence complementary feeding and obesity risk. Early prevention programs, especially those involving parental education on responsive feeding and diet, are promising for reducing obesity risk. Future programs should incorporate parents' perceptions and motivations to improve intervention effectiveness.</p>","PeriodicalId":8269,"journal":{"name":"Annals of Nutrition and Metabolism","volume":" ","pages":"1-12"},"PeriodicalIF":3.2,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142999126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
