Peripubertal dietary flavonol and lignan intake and age at menarche in a longitudinal cohort of girls
2017 •
Frank Biro
Dietary phytoestrogens may alter hormonal activity in childhood. Flavonols and lignans are the most prevalent phytoestrogens in the Western diet.We examined whether higher intake of flavonols and lignans were associated with later age at menarche in a prospective study of young girls. 1044 girls ages 6-8 years (mean 7.3 yr) with 2-4 24 hour dietary recalls during their baseline year were followed for 11 years until attainment of menarche in the Breast Cancer and Environment Research Project (BCERP). Associations of age at menarche with quintiles of phytoestrogens were assessed using hazard ratios (HR) and 95% confidence intervals (CI) from Cox proportional hazards models, controlling for body mass index and other covariates. The highest quintile of flavonol intake was associated with a later age at menarche, compared to the lowest quintile (adjusted Hazard Ratio (HR): 0.80, 95% CI: (0.66-1.00). For lignans, there was a later age in overweight girls (HR: 0.56 95% CI=0.40-0.80). These...

Naturally occurring hormones in foods and potential health effects
Belinda Jenks
Hormones and hormone-like substances, for example, phytoestrogens, are food components that can be endogenously produced by a food source or occur secondary to farming practices. The hormone content of foods has been studied for decades, and safety evaluations in the United States and Europe indicate that naturally occurring hormones found in foods are safe for human consumption. More recent studies have focused on the role of certain hormones found in specific foods (e.g. dairy or soy) and their potential health effects. However, limited summaries exist on food content of hormones and hormone-like phytoestrogens in the context of a comprehensive US diet and implications, if any, of their daily consumption for overall health. This review provides an outline of hormone biosynthesis and functions in the body; discusses the more commonly studied, naturally occurring hormones in food and their biological role within food; estimates relative dietary contribution and when available, bioav...

Is soy intake related to age at onset of menarche? A cross-sectional study among adolescents with a wide range of soy food consumption
2014 •
Mark Messina
Early onset of menarche may negatively influence the future health of adolescent girls. Several factors affect the timing of menarche but it is not clear if soy foods consumption around pubertal years plays a role; thus, we examined its relation to age at onset of menarche (AOM) in a high soy-consuming population. We conducted a cross-sectional study on 339 girls ages 12-18 years attending middle and high schools near two Seventh-day Adventist universities in California and Michigan using a web-based dietary questionnaire and physical development tool. Soy consumption (categorized as total soy, meat alternatives, tofu/traditional soy, and soy beverages) was estimated from the questionnaire, while AOM was self-reported. Data analyses included descriptive statistics, Cox proportional hazards ratios, Kaplan-Meier curves and Poisson regression with adjustment for relevant confounders. Mean (SD) intakes were: total soy,12.9 (14.4) servings/week; meat alternatives, 7.0 (8.9) servings/week...

Plant-Based Diet during the Prepubertal Period and Age at Menarche: A Systematic Review
STEFANI CHRISTANTI
This systematic review aimed to analyze the effect of a prepubertal plant-based diet, through dietary patterns and its nutritional components, on the age at menarche. Systematic searches through Medline (EBSCO), Embase, Health & Medical Collection (Proquest), Scopus, and Google Scholar for articles published between January 2000 and September 2022 in English using the keywords of plant-based diet, age at menarche, and their synonyms identified 673 articles. Articles were screened through titles and abstracts, as well as full-text reviews based on inclusion/exclusion criteria and assessment of research quality using the JBI Critical Appraisal Tools with a JBI cut-off final score of >50%, leaving 12 articles in this systematic review presented in the PRISMA 2020 flowchart. Data analysis was conducted descriptively by comparing findings between articles. Age at menarche/puberty was reported as an outcome of food intake through a vegetarian diet, Mediterranean diet, vegetable protein...
