There are hundreds of claims about healthy foods, and the most dangerous thing about this is that many people accept these claims and try to implement them, even though they have heard them from people who are not experts in the field of nutrition.
In the article published by the Turkish newspaper "Milliyet", journalist Tanay Karkos said that sometimes we impose unnecessary restrictions on our bodies, and make it more difficult to follow a balanced diet because of the false information that we received as a fact.
The writer quoted the food engineer, Ebru Akdag, as refuting some well-known rumors in the world of nutrition by answering the following questions:
1- Long life milk produced by UHT technology under high temperature, which we call canned milk, is it harmful to health?
This question is the most important;
There are those who claim that “UHT milk is useless,” that its manufacturers “add drugs to it” and that it is “addictive.” These are all myths, because UHT: Ultra-high-temperature processing (i.e., UHT: Ultra-high-temperature processing) Ultra-high temperature sterilization) is a superior technology that has been used worldwide since 1961 with the aim of processing liquid foods.
This technology relies on heating milk at a temperature of 135-150 degrees Celsius, then cooling it in a short time from 2 to 6 seconds, and then packing it in sterilized packages (free of germs) and in a sterile environment as well.
Checking the viability of the egg by placing it in a glass full of water (the island)
And if the package is not opened and kept for a long time at room temperature, it preserves its nutritional value, in other words: UHT UHT milk is a product in which its nutritional value is preserved without the need for any protective additives, thanks to all of heat treatment and packaging technology.
2- Some of us store foods by applying the freezing method at home, and some of us resort to frozen canned foods;
Does the nutritional value of frozen foods change?
Does it contain preservatives?
Frozen foods are produced by freezing seasonally harvested fruits and vegetables within a few minutes using the “freeze” system, after they have been washed and cleaned.
In this way, it maintains its nutritional value throughout its shelf life without adding any preservatives. In fact;
Research reveals that the nutritional value of frozen fruits and vegetables is generally higher than that purchased from the market, because fruits and vegetables that are picked from their branches and separated from their roots begin to lose their nutritional value from the first moment, and it usually takes a week to reach the market, which is what It loses its nutritional value.
On the other hand,
Frozen products retain their nutritional value thanks to the technology used, as they are frozen only hours after harvest.
3- Are only roaming chickens (which are not raised in farms) that produce brown eggs?
The color of the egg yolk varies with the breed and diet of the hen, and it is not correct to use it as a quality standard, and there is also no evidence to suggest that the nutritional value of the eggs of wandering chickens (that is, those raised randomly and not in chicken farms) is higher than others.
4- Is a brown-shelled egg better than a white egg?
The color of the egg has nothing to do with its quality, in fact;
The link between the quality of the egg and its color is not different from linking it to the color of the feathers, because the breed of chicken is the determining factor for the color of the egg. The Italian Leghorn chicken produces white feathers and earlobes, while the Australian Orpington chicken produces white eggs. With red, yellow or brown feathers and red ear lobes, it produces brown eggs.
It is worth noting that in the beginning each egg is white, and then the eggs are colored at the end of the 26-hour journey in the hatching channel in the hen, and because the addition of pigments that give the egg its brown color takes place after the formation of the egg, only the outer surface of the shell becomes colored.
5- Is chicken that takes longer to cook normal?
Chickens that are raised in the village are usually old, as their life extends until the slaughter period, so it takes longer to cook, and the chickens that you buy from the market are cooked more easily, as the fastest growing and easy-to-cook small breeds of chicken are produced by industrial methods.
6- Are antibiotics and hormones given to chickens?
Chicken is one of the foods that comes to mind when it comes to “hormonal foods”, to the point that there are a large number of people who say “I no longer bring chicken home”, but it should be noted that the use of growth hormones in chicken is prohibited all over the world.
On the other hand;
This use is illogical from a technical and material point of view, because adding growth hormone to chicken feed does nothing. When it reaches the animal’s stomach, it will disintegrate and become ineffective, and in order for the hormone to be effective, it must be injected into chickens every day and more than once a day, so he will have to The breeder has to spend all day chasing the chickens.
So, in production houses with thousands of chickens;
Do you think it is possible to hunt and inject each chicken several times a day?!
This is illogical.
As for antibiotics, it should be noted that it is prohibited to add antibiotics as feed additives for growth purposes, but they can be added for therapeutic purposes.
7- Do food additives cause cancer?
None of them cause cancer, and if there is the slightest suspicion that food additives may cause cancer, the use of such food additives is not permitted.
Behind allowing the use of food additives lies an army of international scientists who have worked on it for 10 to 15 years;
The Committee on Food Additives includes experts from the Food and Agriculture Organization (FAO) and the World Health Organization.
In addition, the use of food additives is allowed if there is consensus from international food and health authorities such as the European Food Safety Authority and the US Food and Drug Administration.
Regardless of cancer, the use of additives is modified in such a way that if a person consumes this additive every day for 70-80 years of age, he does not notice any effect of it, and it is not allowed to add these substances unless it has advantages that benefit health in order to enter the evaluation stage.
Among its advantages are the following:
Preventing the development of pathogenic microorganisms in food.
Protect the nutritional value of food.
Special production for people with unique nutritional needs.
Increasing the nutritional value by fortifying it with substances that have a positive effect on health such as fiber, vitamins and minerals.
Longer shelf life.
Improving the structural properties, flavor and color of food.
Prevent unwanted reactions such as oxidation that create health risks.
8- Does the fact that the color of butter, whether yellow or white, reveal its quality?
The color of butter depends on the animal's diet. Its color is not an indication of its quality;
If the cow, sheep or goat whose milk has been used, follow a diet based on green fodder such as grass and weeds, the butter will appear yellow because there are more coloring agents in these green fodders;
Where it is transferred to the animal's milk with its food, then it melts in the fat and gives the butter its color.
If the animal, whose milk is used to make butter, is fed feed such as hay, barley, and wheat, the butter is expected to be lighter in color, because these foods do not contain coloring agents.
However;
Since consumers rate the quality of butter according to its colour, coloring agents of vegetable and mineral origin permitted in the Codex Alimentarius may be used in butter production.
9- Does crystallization of honey indicate that it is pure, natural honey?
It is normal for honey to crystallize;
However, this is not a valid indication to provide evidence that it is natural, original, pure or any other conclusion;
Honey may or may not crystallize depending on many influences such as its type, storage conditions, length of storage period, etc., which are the factors that make it difficult for consumers to know its truth, especially since it is one of the foods that can be easily imitated, and for this reason honey must be subjected to laboratory analysis, which tests many advantages to know The authenticity and quality of honey or not.
10- Is consumption of canned products harmful to health?
Is it possible for the metal to transfer to food that is sold canned in metal containers?
Consuming canned products is not harmful to health, and it can have a positive effect in terms of increasing the consumption of vegetables and fruits and preventing food waste, but compared to their fresh or frozen counterparts, the nutritional value of canned foods is slightly lower, but this does not cancel out their being a good alternative to food when we cannot Reach for other varieties or when there is no time to cook.
Usually the packaging used in canned food has passed the necessary tests to prevent any transfer of minerals to the food.
11- Is there plastic in herbal and fruit tea bags?
When you mention the phrase bags, nylon is the first thing that comes to mind, but tea bags are not made of plastic, as the main tea producers in Turkey make them from the fibers of the abaca plant, which looks like a banana tree.
And since linen shirts don't melt when wet, abaca tea bags don't dissolve in hot water.
12- Are 100% natural fruit juices really free of additives?
No added sugar, sweeteners, flavors, preservatives and coloring to 100% natural fruit juices, which means they are very similar to the juice we make at home.
The difference between them is that this type of canned juice undergoes heat treatment to preserve its nutritional value and make it last as long as possible.
13- Are juices made from rotten fruit?
According to the legal regulation for the manufacture of juices, juice must be produced from “hard and ripe fruits that are fresh, frozen or dried”, and the juice cannot be extracted from rotten fruits.
14- Does heating food in the microwave have health risks?
The waves emitted by microwaves are in the form of "electromagnetic" radiation, which is different from ionizing radiation that can damage cells.
These radiations are emitted from various household appliances, such as microwaves, radars, telephones, televisions, and hair dryers.
The exposure of cooked food to radiation when heated in the microwave is a myth.
Scientific research shows that microwaves are safe to use.
15- Is rock salt effective in preventing some diseases?
Like other types of salt, rock salt does not have any special benefits.
Scientific studies have revealed that excessive salt intake leads to high blood pressure associated with cardiovascular disease.
Since sodium represents 97% of the components of rock salt, an excess of it is harmful to health.
16- Is gluten consumption harmful for everyone?
It is recommended that people with celiac, who make up less than 1% of the population, eliminate gluten from their diet, especially those with gluten intolerance or gluten sensitivity.
This is not due to the presence of pathogens in gluten, but rather because the body of people with these digestive disorders reacts differently to gluten.
Gluten is a protein found in grains such as wheat, barley and rye.
A gluten-free diet can negatively affect health if you do not have a problem with gluten.
According to a 2017 report by the American Heart Association, a diet low in gluten increases the risk of type 2 diabetes.
17- Is it safe to use olive oil for cooking or frying?
Olive oil is divided into types, including extra virgin olive oil and refined oil, and each type is suitable for cooking and frying.
Although there are no warnings about using olive oil for cooking, heat treatment of the oils loses some of the beneficial phenolic compounds.
18- Does eating foods subjected to irradiation sterilization lead to the accumulation of radiation inside the body?
The goal of radioactive sterilization of food is to eliminate pathogenic microorganisms, food putrefaction and parasites, and to keep food safe and sound for as long as possible.
Reputable scientific institutions have conducted many researches on this technology for more than 30 years and have proven that foods subjected to radioactive sterilization do not contain radiation.
This has been confirmed by the World Health Organization, the Food and Agriculture Organization of the United States, the International Atomic Energy Agency, the Centers for Disease Control and Prevention and various other scientific bodies.
Even NASA astronauts consume foods that have been sterilized with ionizing radiation to avoid foodborne illnesses during their spaceflights.
