This narrative review highlights recent advances and ongoing trials using nutrition approaches for healthy aging. Focus will be placed on nutrition therapies that target cognition (“the mind”) and mobility (“the muscle”), both critical components to maintaining a high quality of life for older adults. For “the mind,” two seemingly incongruent therapies are being investigated to improve cognition–the MIND diet (high in carbohydrates and anti-oxidant fruits and vegetables) and the ketogenic diet (low in carbohydrates [...]

Exercise induced muscle damage occurs following strenuous and unfamiliar exercise and results in biomarkers of muscle damage and inflammation in the circulation. Creatine (Cr) is a commonly utilized nutritional supplement which has been proposed to enhance post-exercise recovery and has been suggested to decrease exercise induced inflammation. Exercise is well recognized to be beneficial for older adults to maintain skeletal muscle mass and strength as well as promote health for other biological systems. However, o [...]

Exercise-induced moderation of postprandial glycaemia in adolescents is unclear and has not been examined under free-living conditions. We assessed the effect of moderate-intensity exercise (MIE) and high-intensity intermittent exercise (HIIE) bouts on subsequent postprandial glycaemic responses across three standard school days. Fourteen healthy adolescents (13 ± 1 years) completed three conditions in the following order across consecutive days: MIE, 30-min continuous brisk walking; CON, no-exercise control; HIIE, [...]

Inflammatory bowel disease (IBD), which includes ulcerative colitis, and Crohn’s disease, is a chronic relapsing-remitting inflammatory state of the gastrointestinal (GI) system. The cause of IBD is multifactorial, encompassing factors of genetics, environment, and the host immune system, initiating a complex interplay of maladaptive host immune responses and subsequent chronic inflammation. Aberrant host immune responses are at least in part due to changes in the commensal microbiome, which can in turn affect the [...]

Colorectal cancer (CRC) is currently the third most common cancer within the United States among both males and females, with increasing rates occurring in younger individuals compared to the past. Multiple environmental and social aspects including diet may be contributing to this increase in CRC rates. The aim of this review is to examine foods containing high fructose corn syrup, processed meats, and red meats which have shown to be linked to an increase in incidence of CRC. These foods can be a cause for disrup [...]

Flavonoids are phytochemicals (polyphenols) of plant origin. They can trap free oxygen radicals generated by mitochondria and other electronic transport chains, thereby inhibiting inflammatory and carcinogenic changes in vivo and in vitro. Why the body requires these compounds for the well-being of the organism and the maintenance of human health remains unclear. However, a deficit of flavonoids could lead to molecular malfunctions in cells, organelles, and macromolecules. This manuscript describes the occurrence a [...]

Accumulating evidence demonstrates that senescence and the associated inflammatory phenotype (SASP) also occur in post-mitotic cells such as mature adipocytes. Visceral adipose tissue in humans is susceptible to inflammation due to nutritional imbalance and ageing. However, while adipose tissue has been well researched in the context of obesity, senescence of differentiated adipocytes has not been investigated thoroughly. Our group recently demonstrated that ageing and normal ad libitum (AL) nutrition in mice resul [...]

We report the case of a 30-year-old male with significant obesity (body mass index 47 kg/m2) with co-existing moderate obstructive sleep apnoea, hypertension, hypercholesteremia and hypogonadotropic hypogonadism, who was treated with a very-low-energy diet (VLED) and lifestyle modification programme for 12 months. The patient lost weight throughout the entire treatment period (average weight loss was 2.1 kg/week, for a total of 42.7 kg), and showed marked improvement in co-morbidities and no adverse effects. This c [...]

Microbes have been part of the diet throughout human history. In the evolution of food preservation practices, some techniques inadvertently leveraged microbial activity not only to extend the storage life but also to enhance the properties and nutritive value of foods. In the last century, a variety of bacterial species (referred to as probiotics) were found to confer health benefits to the host. The advent of high-throughput sequencing methods facilitated improved surveillance of conventional probiotics within gu [...]

Children with inflammatory bowel disease (IBD) have a high prevalence of vitamin D insufficiency secondary to factors such as malabsorption and decreased intake. In recent years the benefits of optimal vitamin D status have been highlighted for their potential to improve the disease course and long-term outcomes in this population. Clinical benefits have been seen to bone health, the immune system, and gut health, with further improvements to disease and treatment outcomes. Recommendations for vitamin D treatment p [...]
