Happiness is given by… genes

Endless contentment is almost impossible, a new study suggests. But it can be surprisingly close to many of us. The findings of this study may explain why some people are unhappy despite the fact that they are lucky, while others remain happy even in critical situations. "There have been assumptions among psychologists that happiness is primarily determined by genes and is determined by personality traits even before we are born," says Richard Lucas, director of the latest study and professor of psychology at Michigan State University.

Endless contentment is almost impossible, a new study suggests. But it can be surprisingly close to many of us. The findings of this study may explain why some people are unhappy despite the fact that they are lucky, while others remain happy even in critical situations. "There have been assumptions among psychologists that happiness is primarily determined by genes and is determined by personality traits even before we are born," says Richard Lucas, director of the latest study and professor of psychology at Michigan State University.
The psychologist considers that the genes determine in a proportion of one third or even half that a person feels happy or not.

Other factors are divided between major events that can change our life, such as winning the lottery or losing someone dear, but also daily events, such as stress at work or getting stuck in traffic. US researchers analyzed data from two recent studies, one German and one British, in which over 17,000 people participated. Inherited predispositions for contentment and happiness have proven to be consistent factors over the years. The level of satisfaction has changed after certain periods, depending on the major events in the individual's life. "For example, a person who married in 1990 may experience a more intense sense of happiness for that year," explained psychologist Richard Lucas.
Another psychologist, from Michigan's Hope College, agrees with the findings of his colleagues, who actually demonstrate that "our emotional response to positive or negative events has a much shorter life than the world would be tempted to believe." David Myers also believes that feeling of well-being is also influenced by lifestyle.
Another study shows that there are differences according to gender. Thus, Swedish researchers claim that a gene responsible for the onset of depression in girls can actually protect boys from depressive symptoms. The two genes studied by scientists at the University of Uppsala, 5-HTT and MAOA, play a role in how the brain "manages" the signal given by certain chemicals, such as dopamine and serotonin.

Is Healthy Tooth the Secret to Long Life for Women?

Here's another reason to use dental floss: A recent study published in the Journal of the American Heart Association revealed that women with dental disease die prematurely.

Oral hygiene is probably more important than you think


"The risk of fatalities for older women is higher if their periodontal status deteriorates," said the study's author, Michae LaMonte, an associate professor of epidemiology at the University of Buffalo. According to a cardiologist, the results of the study are very interesting. "Oral hygiene is an important part of our body's health, and perhaps this research will stimulate further investigation to accurately understand the impact on the heart," she said. Dr. Rachel Bond, an associate professor at Lenox Hill Hospital. According to the literature, two thirds of people over the age of 60 are affected by tooth diseases. A common consequence of this is tooth loss, which can affect one third of Americans over the age of 60. But is it really true that the health of a tooth affects life expectancy? In response to the request, LaMonte and his team analyzed data from 57,000 women over 55 years of age. They followed women for seven years, killing 3,800, of whom 3,589 died due to heart disease. According to the results of the research tooth disease increased the risk of mortality by 12%.A few ladies had extremely bad oral hygiene, which could have even resulted in the loss of all tooth during the research. Factors predisposing to more than one heart disease were present in these women, they were lower-grade, and they visited their dentist less frequently.

Feeding the baby: how to avoid food allergies

Diversifying children's nutrition and providing solid foods is an important step for all parents, but it is also a joy accompanied by lots of worries and questions, most of which are related to food allergies.

Allergic reactions to food are the way in which the immune and digestive system, still undeveloped, of children defend themselves against possible food threats.

These are manifested through intestinal cramps, bloating, inflammation of the limbs and face, inflammation of the esophagus accompanied by the sensation of suffocation, red spots on the skin and even itching. This is why parents do everything they can to immunize their children so that they do not suffer from allergies. Here are some tips that will help you:

Try to gradually identify the allergens

It is very important to familiarize the child with new foods gradually, so that you can observe any change and know its nutritional origin. If you introduce several foods at once, you may not be able to figure out which of them causes allergic reactions to your child.

The type of new foods and the order in which you introduce them to the baby's diet are not necessarily important, provided they follow a balanced and nutrient-rich diet.

Each time you offer a new food to your child, wait 3-5 days until you introduce another ingredient that you have never tried and do not remove from the diet those foods that you are already used to and which you know are safe because it is impossible to have allergic reactions to them if he has not already had in the past.

The most dangerous foods for the allergic

There are over 160 foods that can give allergic reactions, and some of them are more risky than the other. The most dangerous are milk, eggs, peanuts, nuts, fish, crustaceans, soy and wheat. They are responsible for almost 90% of food allergies and should be introduced later in children's nutrition.

Symptoms specific to food allergies

When you offer a new food to your child, you should follow if it shows allergic reactions. Symptoms may appear immediately after swallowing or a few hours after and include urticaria or inflammation of the skin, erythematous rash, swelling of the tongue, face or lips, vomiting, soft stool, coughing and breathing difficulties or loss of consciousness.

In the worst cases, allergies can be fatal; if you notice any sudden changes or serious manifestations of the symptoms listed above, you should consult a specialist doctor.

Minor symptoms such as urticaria or skin eczema should also be reported to the pediatrician in order to determine their causes and origin, respectively to identify the nature of the allergy.

After you do this, it will tell you what to remove from the baby's diet and how to protect it from exposure to allergens that make it bad. Do not insist on giving your child a certain food, even if the initial reactions are minor, as they may become severe through repeated exposure.

When to start diversifying the meals and giving your child solid food

Some allergies disappear over time. Milk and egg cells gradually fade as children grow and their digestive and immune systems mature. But there are also allergies that never disappear, such as peanuts, nuts or crustaceans.

Until recently, the Pediatric Association of America recommends parents not to give their children milk until they are one year old, eggs up to 2 years old and peanuts, nuts and over 3 years old.

However, these recommendations were made on the basis of expert opinions and did not have a solid scientific basis, so in 2008 it was decided to eliminate them. The current guide suggests that if there is no family history of allergies, there is no evidence that waiting until the introduction of these foods can protect children from allergies.

Therefore, the best advice in this regard can be given by your child's pediatrician, who knows his medical history and who has all the information about your family's allergies.

How to protect your baby from food allergies

Numerous pediatric doctors recommend parents to wait until the age of 9-10 months for the children before giving them the 8 foods with high risk of causing allergies. Although the risks are similar after this age, experience shows that allergies are easier to manage in children older than 9-10 months.

There are still many doctors who, worried about the possible effects, recommend to parents not to offer children peanuts and crustaceans before reaching the age of 3 years. Moreover, cow's milk should not be introduced into the diet before reaching the age of one year, because of the significant differences between it and breast milk, which has a much higher nutritional value.

Yogurt and soft cheese are safe foods even earlier because the proteins in these dairy products are broken down and do not cause problems most of the time.

honey it should not be introduced before one year, as it has been shown to cause infant botulism, even if it is hypoallergenic.
