Studying the Optimal Time for Meals to Circadian Rhythms and Body Health (Application to Hospitality Establishments)

Abstract

Circadian rhythms, metabolism, and nutrition are closely linked, although the effects of meal timing on the human circadian system are poorly understood. The time factor biological of nature is an essential element for the functioning of cosmic systems. In the event of any defect, many problems come out as a result of this imbalance, and here came whether to change the timing of eating diets has to do with the occurrence of illness in the body and the emergence of diseases of this age such as obesity and diseases of the gastrointestinal tract (gallbladder - diseases of the colon, liver, and others). Hence the need to research the effect of timing, eating the three meals, and the body's system to resist disease. The study sample was withdrawn from Egyptian and foreign guests in hospitality establishments in Hurghada, Egypt with 300 forms. SPSS statistical program was used, and the research was focused on the body's sympathetic nervous system and its role in regulating the body processes related to metabolism. The timing of waking up and eating meals reached a set of findings and recommendations. The most important ones are the need to amend the healthy track of food and to increase the awareness of educational health, followed by hotels and resorts’ restaurants and room services offering those meals according to the client’s demand and the time they want to eat the meal. Therefore, it is necessary to direct the food operators in the hospitality establishments to prepare the food at the optimum time and to search for the modification of new food trends in line with the nature and the regularity of the diet to prevent diseases.

Effect of a Training Program Accompanied by a Suggested Diet on Some Physiological Variables and Regulating Blood Sugar Level in Type II Diabetics

“…The study [33] confirmed that the results of the study [34] show that there is an inverse relationship between regularity in performing aerobic exercise and the reduction of total cholesterol, as regular exercise leads to an improvement in the percentage of lipids in the blood. Low density will increase the accumulation of cholesterol in the arteries, and the higher the percentage of low-density lipids, the greater the possibility of heart disease, and the greater the percentage of excess cholesterol in the body, which is a source of danger that results in chronic diseases such as type 2 diabetes.…”

“…A study [29] confirmed that exercise leads to a reduction in the level of low-density lipids and cholesterol in the blood, and the results of this research have been agreed from the study [21]. The training program that applied to the sample members achieved its goals in reducing the proportion of cholesterol and low-density fats [21,[33][34][35]. Shalaby et al [33] confirm that the practice of physical activity reduces levels of low-density fats, and the results of this research are consistent with the results of the study of Budiono et al [36] on a decrease in body fat percentage when exercising regularly, which leads to the prevention of blockage of arteries in the heart.…”

Dendrimer for targeted drug delivery and Vaccine and Immunostimulatory: applications and methods

“…Though, with an oral injection of NSAIDs, their clinical use is often limited due to the intestinal, gastrointestinal, and renal side effects. Dermal medication overcomes these side effects and maintains the healing level of the blood for a long time [205][206][291][292][293][294][295]. One of the disadvantages of dermal delivery is the low delivery rate due to the skin barriers.…”

“…In addition to the tissue toxicity, high-generation amino surfaced dendrimers also result in in ammation and activation of the complement system. As with the membrane interacting, lipid-bearing dendrimers, there is a ne balance between cytotoxicity and stimulation of cellular components of the immune system [230,249,295].…”

“…Dendrimers can carry guest molecules through receptors on their surface or encapsulate them in cavities between branches [32][33][34]293]. The development of molecular nanostructures with appropriate particle size and shape has been considered for biomedical applications such as the delivery of active drugs, imaging materials, or gene transfer [35][36][37]294]. For example, structures used as carriers in drug delivery generally need to be in the nanometer range and in the de nite size to increase their ability to cross the membrane and reduce the risk of clearance from the body through the liver and spleen [38][39][40][41].…”
