The aim of the present study was to introduce Focused Principal Component Analysis (FPCA) as a novel exploratory method for providing insight into dietary patterns that emerge based on a given characteristic of the sample. To demonstrate the use of FPCA, we used a database of 1,968 adults. Food intake was obtained using a food frequency questionnaire covering 26 food items. The focus variables ...

The beverage of Hibiscus sabdariffa flowers is widely consumed in Mexico. Polyphenols contained in plant foods are frequently associated with dietary fiber. The aim of this work is to quantify the dietary fiber, associated polyphenols, and antioxidant capacity of the Roselle flower and the beverage traditionally prepared from it and its contribution to the Mexican diet. Roselle flower contained...

This review will discuss some of the antioxidant assays and biomarkers/measurements used to assess the effect of dietary components on ameliorating in vivo oxidative stress. Although the development of dietary antioxidants has become a major component of the dietary supplement market, this review will focus on foods (primarily fruits and vegetables) and their impact on biomarkers of oxidative s...

OBJECTIVE The objective of this study is to investigate the effects of the UK Pregnancies Better Eating and Activity Trial (UPBEAT) behavioral intervention on dietary patterns in obese pregnant women. METHODS Dietary patterns were derived from Food Frequency Questionnaires using principal component analysis in 183 UPBEAT pilot study participants. RESULTS Two unhealthy dietary patterns, proc...

We examined the effect or not of an antibiotic treatment on dietary fiber-induced goblet cell proliferation in the rat ileum. The number of goblet cells in the ileum increased when rats consumed dietary fiber. However, this effect was maintained with a concurrent treatment of antibiotics, suggesting that the fiber effect on goblet cell response would remain irrespective of a bacterial component...

J P Context: The Supplemental Nutrition Assistance Program (SNAP) is an effective component in reducing food insecurity in the U.S. In the discussion of strategies to also help SNAP participants maximize diet quality, it is important to know their current dietary patterns and food choices. This paper provides a systematic review of recent U.S. studies on dietary quality, food consumption, and s...

Description Medium chain triglycerides (MCTs) are a class of lipids in which three saturated fats are bound to a glycerol backbone. What distinguishes MCTs from other triglycerides is the fact that each fat molecule is between six and twelve carbons in length. MCTs are a component of many foods, with coconut and palm oils being the dietary sources with the highest concentration of MCTs. MCTs ar...
