“If you drink a lot of water you lose your appetite and lose weight “. This belief that runs on the net is false, according to theCollege of Health that on its website has created an area dedicated to buffaloes. We offer our readers the text to dispel one of the many myths that crowd the internet.
Drinking too much water, as well as drinking too little of it, is harmful to health because, among other effects, it can determine the dilution of electrolytes in the blood, especially sodium and potassium, which have an essential function in the balance of liquids between the internal and the outside of the cells. To maintain a good state of health, the human body needs the right amount of water in order to replenish water losses, thus ensuring optimal conditions for most physiological processes. Signs of excessive water intake are headache, nausea and He retched, increase in blood pressure, confusion, sleepiness, difficulty breathing, asthenia (tiredness). The European Food Safety Authority (EFSA) Scientific Panel on Dietetic Products, Nutrition and allergy, has recently redefined the dietary reference values of several nutrients, including water, recommending the amount that is necessary to be in good health according to age and gender.
The reference values, which consider the water taken as a whole – both through direct consumption and through food and beverages of all kinds – in conditions of moderate environmental temperatures and medium levels of physical activity, are defined as follows:
– in newborns up to six months of life: 0.1 liters per kilo of weight per day (l / kg / day)
– in children: between 6 months and one year of age: 0.8-1.0 liters per day (l / day); between 1 and 3 years of life: 1.1-1.3 l / day; between 4 and 8 years of age: 1.6 l / day; when the age is between 9-13 years: 2.1 l / day for boys and 1.9 l / day for girls
– in adolescents, adults and the elderly: for females 2 liters per day; for males 2.5 l / day
The values are indicative; in conditions of hot climates and intense physical activities, or other situations that induce dehydration, the levels of water to be taken can vary significantly (it can also be considered more than double the quantities indicated). This also occurs under conditions of stress e gastrointestinal disorders causing vomiting e diarrhea, as for infant diarrhea.
