Very soon, engineers invented machinery that reduced human physical efforts. People no longer need to go upstairs on foot when they have an elevator. What is more, they grow more food that resists the negative impact of the environment. Therefore, we have machines, fast food and genetically modified food products that influence our health negatively. Modern people suffer from the lack of motion and physical activity. Furthermore, they consume unhealthy food that contains fat and sugar.

If we consume healthy high-quality food, we feel better and all the systems of our body work in the proper order.

What is healthy eating? There is no need to write about fast food inasmuch as everyone understands that it contains much fat, salt and sugar. Healthy eating is the consumption of the products that provide our organism with the required microelements and vitamins. What products contain the required elements?

You cannot eat only porridge or cornflakes all the time. You should vary the choice of your dishes. Moreover, it is useful to combine different dishes making complex meals.

It is no less important to eat regularly. It is reasonable to start your workday with a nourishing breakfast.

Physical health is a valuable but easily spent resource. Not speaking of serious chronic diseases, there are a lot of minor, less noticeable threats that can nevertheless affect one’s physical condition and productivity: the common cold, headaches, and nausea are among them. However, among these minor threats, the most distressing one is perhaps food poisoning, which can easily incapacitate a person for at least several days.
A person usually gets food poisoning as a result of consuming contaminated or spoiled food and drinks. It often happens at picnics, in school cafeterias, restaurants, and other similar places. There are different ways food can get contaminated. For example, meat can become contaminated by contacting the intestines of an animal being processed; water can contact animal or human waste and become infected as well. Generally, contamination occurs when food is improperly processed or stored. Other ways of contamination include dirty hands, improperly-cleaned cooking utensils, an expired expiry date, and so on. Besides, a person can get food poisoning when consuming raw or under-cooked products—fruit, vegetables, fish, eggs, or meat (Medline Plus).
Generally speaking, food poisoning is an intoxication caused by low-quality food. However, a more meticulous scrutiny reveals that food poisoning has a lot to do with malicious bacterium; commonly, these bacterium comprise Campylobacter, Salmonella, Shigella, Listeria, and some others. Although they are, in general, not life-threatening, in rare cases there can be serious complications caused by the exposure to these bacterium, such as reactive arthritis or brain/nerve problems (Web MD).
Symptoms of food poisoning include fever, nausea, diarrhea, vomiting, general weakness, and strong abdominal pain or cramps. Usually, the symptoms start within the first several hours after contamination, but in some cases, food poisoning symptoms can remain hidden for days or even weeks. The sickness usually lasts up to three days; in the majority of cases, one can treat the sickness themselves: usually it is enough to adhere to a special diet (often it is is recommended to eat boiled rice, and drink a lot of strong tea or plain water) and take charcoal pills. However, there might be cases when it is crucial that a person with food poisoning visits a doctor. The list of disturbing symptoms includes bloody vomit or stools; diarrhea for more than three days; an oral temperature higher than 101.5 F; dehydration, severe weakness, and neurological symptoms such as blurry vision or tingling (Mayo Clinic).
Food poisoning is a common but distressing digestion disorder usually caused by the consumption of contaminated food. In order to minimize the risks of developing the symptoms, which include nausea, diarrhea, weakness, fever, and some other manifestations, one should avoid eating raw or under-cooked food, wash hands before meals, and always check the expiry date on a product package. Food poisoning is easy to treat, but there are cases when it is better to seek medical aid; these cases include having blood in one’s vomit or stool, dehydration, high oral temperature, and neurological symptoms.
