1. Proper hydration of the body
Since water is involved in metabolic processes, the demand for this component increases with increased dietary energy value. The amount of water in the body should always be at the same level, i.e. the so-called water balance must be zero. Table 1. Healthy and healthy human diet, Warsaw 2010.2. Dehydration of the body symptoms
This results in decreased physical activity, reduced thermoregulation, and a lack of appetite. The body does not have the ability to store water, so the lack of water in the diet quickly leads to dehydration. Increased hydration leads to problems with concentration, headache, drowsiness, nervousness, increased body temperature, and breathing frequency.3. Dehydration of the body effects
Dehydration leads to serious health effects such as: pain and dizziness, impairment of cognitive function, motor function,?? problems with speech, heart rhythm disorders, renal insufficiency, changes in blood pressure, constipation, dry skin, improper use of medicines, impaired secretion of saliva.4. Coffee and tea as a source of water
The U.S. Department of Agriculture (USDA) has issued a statement recommending that liquids without added sugar be consumed in order to reduce the amount of added sugar in the diet. The US Agency for Water Resources for Man is drinking water, various types of beverages, and food products. However, it does not pay attention to fast-acting drinks such as coffee and tea. The Food and Drug Administration (FDA) recommends that healthy adults consume no more than 400 mg of caffeine per day, equivalent to about 34 cups of coffee. Coffee ranks as the second most commonly consumed beverage for humans.5. Whether coffee and tea are hydrating
In addition, further studies confirm that moderate intake of caffeine does not contribute to significant dehydration of the body. In this study, 18 men aged 2439 drank a total of 624 mg of caffeinated beverages per day. In men, a reduction in total body water intake (> 500 mg) was observed at high doses (> 42 mg) and a decrease in confirmed urine intake by 42%. Furthermore, the author of the study confirmed that the moderate body weight intake in caffeine-induced beverage was not significant. In the same study, the authors of the A. Killer, A. Jenkins, and other experts from the University of California, San Diego, established that the effects of regular drinking of caffeina on the body weight of the caffeine consumed by caffeine were not based on the actual body weight and weight of any of the drinkers who consumed it.6. The caffeine content of coffee and tea
The level of caffeine in tea depends on the variety, the cultivation conditions, the degree of fermentation, the type and the way it is brewed. The caffeine content in coffee also varies, depending on the type of grain, the production process and the method of brewing. The table shows the average caffeine level in selected coffee and tea strains.
