Insights on oxidative stress Free radicals are molecules that are formed inside the body’s cells when oxygen is used in metabolic processes to produce energy (oxidation process).These molecules are particularly unstable because they have only one electron instead of two; this leads them to seek a balance by taking the electron from other molecules with…

The broader picture Every day nutritionists face the need to balance the food energy intake with the metabolic needs of the patient.In the still predominant practice of low-calorie diets, for example, the aim is to reduce more or less significantly the daily energy intake provided by food (typically measured in Kcal) compared to the estimated…

Physio-pathological interactions and alterations As a rule, hot and humid seasons record increasing cases of malaise and disorders linked to altered hydro-electrolytic balance. All population groups are at risk – more so in recent years due to worsening climate change.As a result, a significantly higher amount of fluids is transferred to the outside environment (with…

A challenging picture According to a study carried out in 2001 [1], 9.4% of women over forty (i.e., since a very young age) and 11.8% of men over sixty are affected by osteoporosis. The numbers increase considerably if referred to osteopenia (for the same population groups the figure is 47.2% for women and 46.1% for…

Vitamins and minerals are key micronutrients for the good functioning of our immune system, and they need to be introduced into the body through proper nutrition. During the winter, however, when colds and flu are easy to catch, it is necessary to increase our body’s defense by supporting physical barriers, cellular immunity and antibody production.For…

Persistent activation of the HPA axis and presence of MUS Circadian rhythm of the HPA axis and stress factors In principle, the physiological circadian rhythm of the HPA axis is regulated at the level of the hypothalamus [7], specifically by the region of the suprachiasmatic nucleus (SCN), located immediately above the optic chiasm and connected…

There are 3 different types of fat or adipose tissue: WAT (white adipose tissue), BAT (brown adipose tissue) and beige. White adipose tissue (WAT) is not only an energy reservoir but, being a highly active endocrine organ, it is closely related to obesity, increased pro-inflammatory cytokines, altered lipid profiles, blood glucose levels and subsequent insulin…

Introduction The combination of dietary excesses and sedentary lifestyle promotes weight gain and obesity, with all the consequences that derive from them. In the ongoing fight against obesity and related disorders, several strategies have proven successful in activating the thermogenesis of brown adipose tissue (BAT) and the energy expenditure of the whole body (EE24h) through…

Non-volatile Acidosis, Volatile Acidosis and Buffer Systems Introduction The metabolic processes that occur within our body lead to constant pH changes through a continuous succession of intake-elimination of “acids” and “bases” that alter the concentration of the hydrogen ion (H +), thus changing the pH of the body that must cope with these variations and…

What it causes, what triggers it, how to monitor it and how to recover from it Inflammation is a normal defence mechanism that protects the body from various insults and pathogens, as well as the tissue repair processes, and helps restore the physiology of infected or damaged sites. It is a mechanism, characterised by redness,…
