Background It has been suggested that the increase in carbohydrate at the expense of fat has contributed to the obesity epidemic in North America and some European countries. However, obesity rates in China have increased rapidly in parallel with a transition from the traditional low fat, high carbohydrate diet to a diet relatively high in fat and...
Article
Bacteria in human milk could directly seed the infant intestinal microbiota, while information about how milk microbiota develops during lactation and how geographic location, gestational hypertensive status, and maternal age influence this process is limited. Here, we collected human milk samples from mothers of term infants at the first day, 2 we...
Article
Background & aims Intestinal short-chain fatty acids have been demonstrated to modulate host energy metabolism and are elevated in overweight and obese individuals. We hypothesized that other intestinal energy products especially tricarboxylic acid (TCA) cycle intermediates might also related to overweight status. In addition, little information is...

Article
Obesity and cardiometabolic diseases in both developed and developing counties in a state of nutrition transition are often related to diet, which also play a major role in shaping human gut microbiota. The human gut harbors diverse microbes that play an essential role in the well-being of their host. Complex interactions between diet and microorga...
Article
Short-term intervention studies supported a link between animal-based diet and the outgrowth of microorganisms capable of triggering inflammatory bowel disease. However, whether habitual animal fat intake is associated with gut-related health remained unclear. Thus, we collected dietary information, clinical data and fecal samples from 297 healthy...
Article
Scope: Vegetarian diets confer health benefits to many cardiometabolic diseases, while whether and how gut microbiota in vegetarians contributes to host metabolism remains unclear. Thus, we aimed to explore the possible links between the gut microbiota and circulating gut microbiota-host co-metabolites among vegetarians and omnivores. Methods and...

Objective To investigate whether diets differing in fat content alter the gut microbiota and faecal metabolomic profiles, and to determine their relationship with cardiometabolic risk factors in healthy adults whose diet is in a transition from a traditional low-fat diet to a diet high in fat and reduced in carbohydrate. Methods In a 6-month rando...
Article
Background & aims: Observational studies have shown that diets high in fat and low in dietary fiber, might have an unfavorable impact on bile acid (BA) profiles, which might further affect host cardiometabolic health. In the current study, we aimed to evaluate the effects of dietary fat content on BA profiles and associated gut microbiota, and the...

Aims: To (i) evaluate the global impact of interventions designed to prevent excessive gestational weight gain (eGWG) on the incidence of gestational diabetes (GDM), and (ii) examine whether the effects differ by pre-conception body mass index (BMI) or ethnicity. Methods: A systematic search of randomised controlled trials (RCTs) with a primary...
Article
The health benefits of fish oil, and its omega-3 long chain polyunsaturated fatty acid content, have attracted much scientific attention in the last four decades. Fish oils that contain higher amounts of eicosapentaenoic acid (EPA; 20:5n-3) than docosahexaenoic acid (DHA; 22:6n-3), in a distinctive ratio of 18/12, are typically the most abundantly...

Context Maternal hypertensive disorders during pregnancy are suggested to affect obesity risk in offspring. However, little is known about the prospective association of rise in maternal blood pressure within normal range during pregnancy with this risk for obesity. Objective To clarify the associations of diastolic and systolic blood pressure dur...
Article
Background and objectives: Findings from observational studies in China show that increased dietary fat consumption might be a contributor to the developing obesity epidemic. However, some cohort studies suggest that carbohydrate intake, especially from white rice, is a risk factor for obesity, type 2 diabetes and coronary heart disease in China....
