Fish Oil Supplementation Favorably Alters Markers of Vascular Function

Endothelial dysfunction (dysfunction of the endothelium, or the inner lining of the arteries), involves damage to the artery lining that triggers inflammation and the development of lesions characteristic of atherosclerosis, the accumulation of plaque buildup in the arteries. Endothelial dysfunction (ED) occurs very early and throughout the atherosclerotic process. ED indicates an imbalance between endothelial damage and repair, which can…

Omega-3 Supplementation Improves Behavior Problems in Children

Antisocial personality disorder is a mental disorder in which the individual often lacks empathy and tends to be callous, cynical, and contemptuous of feelings, rights, and sufferings of others. Poor nutritional status during pregnancy has been linked to the development of antisocial personality disorder in adulthood.1 Poor nutrition is a possible risk factor for the development of antisocial behavior due…

Low-Dose Antibiotics During Early Infancy Trigger Obesity Later in Life

Early life is a critical development period in many respects, and particularly as it relates to gut microbial composition. Even before birth, gut microbes are transferred from mother to fetus, a transfer that continues during birth and later via breast milk. Once established, gut microbes in the infant play a protective role on the infant’s health. A disturbance of gut…

Elimination Diet for Allergic Esophagitis

Eosinophilic esophagitis (EoE) involves an inflammatory response in the esophagus that causes stiffening or swelling and leads to difficulty swallowing or food getting stuck. High amounts of white blood cells called eosinophils are found in the esophagus tissue in people with this condition. In most cases, people with EoE have other allergic conditions such as asthma, rhinitis, eczema, or food…

Getting Fat—The Result or the Cause of Overeating?

We have been told that all it takes to lose weight is a reduction in calories and/or an increase in energy expenditure (exercise). So if we eat less calories or exercise more or both, we will lose weight. Supposedly, that’s how it works. And yet, we continue to struggle with losing weight and keeping it off for good. Only a…

Immature Microbes in the Guts of Malnourished Children

Malnutrition (severe or moderate acute malnutrition) affects 23 percent of children in developing countries.1 The World Health Organization estimates that malnutrition is the cause of one-third of all child deaths.2 Malnutrition, or inadequate nutrition, manifests most noticeably as delayed growth, but also includes deficiencies in vitamins, minerals, essential fatty acids, and protein. A recently developed intervention for severe acute malnutrition,…

Human Placenta Contains a Community of Microbes

The human microbiome is vast, accounting for 90 percent of our cells. Microbial composition varies from site to site across a range of niches in and on the body. Some niches—such as the colon—are colonized by a very high number of microbes. Other niches—such as the stomach—are colonized by lower amount of microbes. There are yet other areas of the…

New Appetite-Suppressing Benefit of Fiber Discovered

It is well known that fiber has appetite-suppressing properties. In fact, Brenda and I wrote an entire book about it—The Fiber35 Diet. Fiber works in a number of ways to suppress appetite. Fiber expands in the stomach, taking up more space, which makes you feel full. In addition, fiber slows the emptying of food from the stomach into the intestines,…

Gut Microbes in a Hunter-Gatherer Community

Researchers are hard at working trying to characterize the human gut microbiome, the community of microbes that live within the digestive tract of humans, mostly concentrated within the colon. A number of studies have begun to classify the microbes found in people of the Western world, and a few studies have even classified the microbes found in rural populations in…
