BACKGROUND Poor diet increases the risk of both colorectal cancer and type 2 diabetes. We investigated the role of diet in the association between diabetes and colorectal cancer. METHODS We analyzed data from 484,020 individuals, aged 50-71 years who participated in the prospective National Institutes of Health-AARP Diet and Health Study and were cancer(More)
BACKGROUND Income disparities in mortality are profound in the United States, but reasons for this remain largely unexplained. The objective of this study was to assess the effects of health behaviors, and other mediating pathways, separately and simultaneously, including health insurance, health status, and inflammation, in the association between income(More)
Anticipatory hunger is a learnt increase in intake of food having a flavour or texture that predicts a long fast. This learning was studied in rats trained on a single food or a choice between protein-rich and carbohydrate-rich foods, presented for 1.5 h after 3 h without maintenance food at the start of the dark phase. Eight training cycles provided a(More)
Several recent experiments have provided evidence that the ingestion of a distinctive food by rats can be a learnt instrumental act as well as an associatively conditioned reaction. In the previous work, maintenance food was withheld for shorter and longer durations on different days following access to the training food. Extra eating before the longer fast(More)
OBJECTIVE Weight reduction is a key goal for the prevention of vascular complications in obese individuals with type 2 diabetes, but a nutritionally balanced intake is also important in this regard. We compared dietary intakes and vitamin supplement use between obese and nonobese women and men with type 2 diabetes to identify gaps in adherence to(More)
OBJECTIVE To assess the association between breakfast energy and total daily energy intake among individuals with type 2 diabetes. DESIGN Cross-sectional study. Daily energy intake was computed from a 24 h dietary recall. Multiple regression models were used to estimate the association between daily energy intake (dependent variable) and quartiles of(More)
BACKGROUND Nutrition education (portion sizes, balanced meals) is a cornerstone of diabetes management; however, moving from information to behavior change is challenging. Through a single arm intervention study, we recently demonstrated that combining education with group-based meal preparation training has measureable effects on weight, eating behaviour,(More)
BACKGROUND Type 2 diabetes is associated with low-grade systemic inflammation, increasing the risk for various adverse health outcomes. PURPOSE Our objective was to investigate the association between C-reactive protein (CRP), a marker for systemic inflammation, and lifestyle factors in a national sample of people with type 2 diabetes. METHODS This(More)
Food intake can be increased by learning to anticipate the omission of subsequent meals. We present here a new theory that such anticipatory eating depends on an associative process of instrumental reinforcement by the nutritional repletion that occurs when access to food is restored. Our evidence over the last decade from a smooth-brained omnivore has been(More)
Rats can learn to anticipate the omission of subsequent meals by increasing food intake. Our previous reports have analysed group means at each trial but that does not allow for rats learning at different speeds. This paper presents instead a rat-by-rat analysis of all the raw data from previous experiments. The re-analysis supports the published evidence(More)
