Longevity: epigenetic and biomolecular aspects
2015
AbstractMany aging theories and their related molecular mechanisms have been proposed. Simple model organisms such as yeasts, worms, fruit flies and others have massively contributed to their clarification, and many genes and pathways have been associated with longevity regulation. Among them, insulin/IGF-1 plays a key and evolutionary conserved role. Interestingly, dietary interventions can modulate this pathway. Calorie restriction (CR), intermittent fasting, and protein and amino acid restriction prolong the lifespan of mammals by IGF-1 regulation. However, some recent findings support the hypothesis that the long-term effects of diet also involve epigenetic mechanisms. In this review, w…
Diet and Immunosenescence
2013
Ageing is a systemic condition leading to a gradual loss of molecular and cellular fidelity. A feature of ageing is immunosenescence, consisting in several modifications that increase morbidity and mortality in elderly. Environment, genetic background, immune system, and intestinal microbiota play a fundamental role in immunosenescence. The development of a chronic, low-grade, inflammatory status, known as “inflamm-ageing,” is a typical aspect of immunosenescence mostly due to the pro-inflammatory cytokine production linked to the chronic antigenic load. Nutrition can act on ageing, immunity, and health in general. Unbalanced diet with an insufficient intake of micro- and macronutrient and …
Oxidative markers in children with severe obesity following low-calorie diets supplemented with mandarin juice
2010
Aim: To evaluate the effect of supplementing a hypocaloric diet with mandarin juice, a food with a high content of antioxidants (vitamin C, flavonoids and carotenoids), on biomarkers of oxidant/antioxidant status of severe obese children. Methods: Forty obese children were randomized into two groups pair-wise in a 4-week controlled intervention study. Both groups followed a hypocaloric diet. One group received additionally a supplementation of 500 mL of 100% mandarin juice daily. Clinical data, anthropometry, dietary intake and fasting blood samples were collected at baseline and after the intervention. Lipid peroxidation was assessed by circulating levels of malondialdehyde, and protein …
<p>Exercise Training and Fasting: Current Insights</p>
2020
Fasting is defined as the abstinence from consuming food and/or beverages for different periods of time. Both traditional and modern healthcare systems recommend fasting as a therapeutic intervention for the management of several chronic, non-infectious diseases. Exercising during a fasting state increases lipolysis in adipose tissue while also stimulating peripheral fat oxidation, resulting in increased fat utilization and weight loss. A key focus of this review is to assess whether endurance training performed while fasting induces specific training adaptations, where increased fat oxidation improves long-term endurance levels. Fasting decreases body weight, lean body and fat content in b…
Hypertriglyceridemia and Omega-3 Fatty Acids
1988
Recent studies by Bang and Dyerberg (1) have stimulated interest in the metabolism of omega-3 fatty acids and have suggested a link between the ingestion of these fatty acids in a diet and the low death rate from athersclerotic disease in Eskimos. In Japan, where fish consumption has traditionally been high, a concommitant shift in tissue lipid consumption favouring omega-3 polyunsaturated fatty acids has been interpreted as causative of a relatively low incidence of cardiovascular disease (1). When analyzing Eskimo food consumption, it became clear that the consumption of omega-3 PUFA is much higher besides a 50% reduction of saturated fat and a relatively high content of monounsaturated f…
Considerations regarding the alleged association between Herbalife products and cases of hepatotoxicity: a rebuttal.
2014
We thank Dr. K Appelhans et al. for their comments [1] on our paper [2], published online first in April 2012. In our review, we aimed to draw the attention of physicians to the uncontrolled and increasingly alarming use of herbal products and dietary supplements in the general population. In fact, in Italy this phenomenon, though still limited, has rapidly increased over the last few years. Here, use of herbal medicine products has increased to 3.7 %, while in other countries consumption is higher, reaching 20 % in the UK, and 40 % in the USA. Young non-smoking women with a high level of education appear to be the most common consumers [3]. It seems that women use these products more than …
A deep learning segmentation approach to calories and weight estimation of food images
2019
Master's thesis Information- and communication technology IKT590 - University of Agder 2019 Today’s generation is very aware of what they are eating and the amountof calories in their food. Eating too many calories can lead to increasedweight, which has become a big health issue. A study from 2016 states thatmore than 1,9 billion adults are overweight where almost one third of theseare obese. Statistics from Norway show that 1 of 4 men and 1 of 5 womenare obese.Artificial Intelligence in general and deep learning in particular can be usedto help understand the content of eaten food. In this master thesis, wepropose a network to estimate the weight of food from a single image. Thisis done in…
A novel nutrient blend mimics calorie restriction transcriptomics differentially in multiple tissues of mice
2017
Identification of caloric restriction mimetics (CRMs), compounds that mimic the beneficial effects of caloric restriction (CR) without restriction of dietary energy would be an advancement in anti-aging science. The present study investigated whether the transcriptional profiles of a putative CRM nutrient blend could mimic that of CR in diverse tissues following long-term feeding in B6C3F1 male mice. Study design: Young Controls (YC; 5 mo.) and 3 groups treated from 14-30 mo.: Old Controls (OC), Old CR (OCR; 25% CR) and Old Supplemented (OS); n=7/group. Gene expression profiling in cerebral cortex (CCT), skeletal muscle (gastrocnemius)(SKL), heart (HRT), white adipose tissue (WAT) and liver…
The Use of Polyols in Pediatrics
1969
Children have a high demand of sugars or similar substances. These ought to be tolerable and easily utilized, furthermore palatable if given by mouth, and apt to supply a sufficient caloric intake. Often, carbohydrates are used as the only source of calories for ill children, e. g. in case of acute disturbances of the intestinal tract (caused by infection or incompatibility of food ingested, by malabsorption syndromes etc.) and in stress situations.
J14 Mediterranean Diet And Nutritional Composition Of Patients With Huntington's Disease. Spanish Multicenter Study Of The European Group For Hunting…
2014
Background The impact of a diet is well known in human health. Intake of food groups (fruits and ‘uts, vegetables, legumes, olive oil, whole grains, fish and wine) in the traditional Mediterranean Diet (MeDi) and high MeDi adherence have been associated with lower incidence of chronic diseases and slower cognitive decline, but the relationship between MeDi adherence and nutritional composition has not been reported. Objectives To describe MeDi and nutritional composition in patients with HD. Methods Spanish multicenter, cross-sectional study (EHDN). To assess MeDi we used a 3-days dietary record. Food groups, macro and micronutrients and energy intake information were obtained using the sof…
