The truth behind widespread nutritional myths

There are few times when our perceptions about the diet touching the realm of science fiction, and often the information we receive eg from our internet cause of confusion to agitation, especially when they relate to issues ygeias.Me expect our food choices greatly affect health and our appearance, let's look at the most widespread nutritional myths and the truth that lies behind them!

Myth 1: The black bread has fewer calories than white Yet the "battle" black and white bread is almost a tie, with the second to deliver around 5 calories per slice above! Of course in nutritional value superior wholemeal bread (black) and is richer in nutrients and fiber, while having a lower glycemic index compared with white.
Myth 2: "Stuck" my metabolism and I do not lose pounds To lose one pounds must employ fewer calories than it spends. In addition, a slimmer requires less energy than a heavier to syntirithei.Kata during a slimming diet, therefore, where the body weight is reduced, it comes that the energy take from food is equal to that body "burns" you. That is why your weight statheropoieitai.Ara So you do not lose pounds, not because it "takes" your metabolism, but because they hire more calories than you "entitled" your new, lower weight, body.
Myth 3: The light foods do not help in weight loss.

Can often in our minds to questions generated, but the scientific evidence to date support that the light food can be a powerful ally in weight management effort, enough to be consumed in moderation and as part of a balanced and active lifestyle.

The "misunderstanding" surrounding their effectiveness is rooted in the fact that many believe that the light products are not fattening. The result; To consume them in large quantities! But "light" does not mean "calorie-free".

With the exception of some light refreshments and cold drinks, actually pay little or no calories, the other "light" versions of foods and beverages continue to provide energy (calories). Moreover, according to the food legislation, 'light' are considered as food and beverages with 30% less energy than "normal". Checking labels and comparing light versions with standard products, we can identify the individual differences (eg, 1 slice of yellow cheese has about 75 calories and 1 slice of yellow cheese with low fat 55 calories).

So when, as part of a balanced diet, the light food or drinks replace the corresponding full, then manage to reduce calories of diet and give a valuable "helping hand" to weight loss if consumed in moderation of course.

Myth 4: Sugar prohibited in weight loss diets If the coffee is plain for you the first measure against overweight, then the time has come to think again, because the truth about sugar is not so bitter. Sugar belongs to simple carbohydrates, making a "fuel" that provides instant energy to the body, and has now been confirmed that moderate consumption can be part of a balanced diatrofis.Min forget that the "key" for proper weight management located on the three -meter-balance variety, that basically means that no single food or ingredient is not considered "forbidden" or responsible itself for the upward trend of the index zygarias.Akomi So in slimming diets, sugar is not considered prohibitive. Instead, you can enjoy the sweetness, integrating it in moderation in a balanced diet lite, always according to your needs in energy and nutrients and in accordance with the recommendations of your dietician. Myth 5: The oil is nutritious food and therefore not fattening Indeed, olive oil consists of so-called "good" monounsaturated fat and is a nutritious food, on the other hand, however, it still belongs to the category of fat, which means that it is rich in calories! So every gram fat provides you with 9 calories, which is more than twice if you compare it to carbohydrates (bread, sugar, pasta, etc.) and protein (red meat, fish, poultry, etc.) that yield 4 calories per So grammario.Meinete away from the excesses and make sure to consume olive oil in moderation. The excessive use of moreover can even turn your salad into a "bomb" calories.
Myth 6: It is important to drink 8 glasses of water a day

Measure and remeasured until you catch the coveted goal, to be honest, has now overturned! First, each of us has its own water needs, according to sex, age, physical activity and environmental conditions. Moreover, while the water must be the first choice, but not the only hydrating agent.

In fact, water recruit from all liquid drink, but also from many foods, such as fruits, vegetables and yogurt. Indeed, it has been estimated that 20-30% of the liquids need daily ingested from solid food, the remaining 70-80% of the drinking water and all non-alcoholic beverages consumed in a day.

So the newest scientific data and recommendations of the European Food Safety Authority (EFSA), not only limited to water, but clearly said the 2 to 2.5 liters of water must be ingested daily (women and men respectively) can be covered from all sources.

What does this mean in practice? That you can put on your taste and hydration selecting beyond drinking water, through a variety of non-alcoholic beverages such as juices, milk, soft drinks, coffee and tea.

Remember that many drinks contain calories, which should be included in the total daily intake, while their light versions can be an additional source of hydration with a pleasant taste but fewer or no calories

Myth 7: The "E" appearing on food labels are dangerous

The original E you see on food labels has its roots in the word "dangerous", but the word (E) UROPE and simply means ... (E) urope Coding! E is a classification code representing a food additive has been assessed as safe and approved by the European Commission (EU). If your mind food additives are still "misunderstood" know that without them we could not consume most of our favorite products.

Essentially, these are ingredients added to food in order to maintain a nutritious, tasty and above all safe, eg preventing deterioration would be hazardous to our health.

Some of them are of natural origin, such as lycopene from tomato that is used to give red color, one contained naturally in foods but synthesized for practical reasons, such as ascorbic acid (vitamin C) protected from oxidation, and some are synthesized to yield a particular characteristic, such as aspartame, which is composed of two amino acids (essential components of proteins) to give a sweet taste without calories.

All food additives, regardless of the origin and type, go through the same rigorous evaluation by the European Food Safety Authority, which not only allows their use if it is proved to be safe, but also reassess at regular intervals so that we are always confident that the additives are safe ingredients in our food.

Myth 8: The low calorie sweeteners such as aspartame, are unsafe

There are few times especially on the internet we find inaccurate information questioning the safety of low calorie sweeteners such as aspartame or a relative or friend warns us that "hurt" ... The truth however is that you occasionally hear have no scientific status.

The low calorie sweeteners such as aspartame, acesulfame-K, saccharin, sucralose, and steviol glycosides (sweetener from the stevia plant) belonging to food additives and therefore approved for use in foods and beverages after a safety assessment by EFSA and confirmed that there are no short-term or long-term side effects in humans.

Indeed, the available scientific data testify that the non-caloric sweeteners can be safely consumed by all population groups, such as pregnant women, lactating women, children and people suffering from diabetes.

For example, aspartame, commonly found in the "dock" is probably the more extensively studied food additive, which has repeatedly confirmed that it is safe eg by the European Food Safety Authority (EFSA), which is the body responsible for food safety in the European Union.

Something that is also not well known, is that aspartame is comprised of two amino acids (aspartic acid and phenylalanine), building blocks of proteins, which are found in protein-containing foods such as meat, milk, eggs, and small amount of methanol also contained in various fruits and vegetables. Aspartame is metabolized in the human body, just like metabolized and other protein foods.

Myth 9: addicted to sugar

The preference for sweet taste is rooted in our genes and is a potential survival mechanism we use in our infancy and directing us to nutritious, safe food, such as fruit or milk.

That wish periodically something sweet, indeed, there is something strange, since our sweet taste creates pleasure, a feeling that overwhelms us, not only when we taste a fresh and generally tasty food, but also in a wide variety of our daily lives, as for example when we embrace our child or when you laugh.

Thus, to date scientific data indicate that sugar creates hand feeling of pleasure, but does not cause addiction in humans. Eating behavior, the way that we think and behave towards food that determines how often and in what quantities will consume any kind of tasty dish.
