What determines longevity?
A team of researchers has found that there is a very clear relationship between what being lives and the speed at which their telomeres – the structures that protect the genes in the chromosomes – shorten. This is the main conclusion of a study published in the journal PNAS, in which researchers also show that this relationship can be expressed with a mathematical equation, a formula capable of accurately ...Read full article...
Essential nutrient reduces cardiovascular disease by 70%
In a balanced diet all nutrients are important, but there are some that, by the role they play in the body, are indispensable. One of them is omega 3, the best ally of the heart.

Avoid disappointment and frustration by learning to say NO
Are you a people pleaser or a submissive person? Maybe it’s time to say no, without remorse. One of the most important elements that defines emotional intelligence is assertiveness, understood as the ability to honestly express our rights, beliefs and needs without denying those of others. It seems easy, but relationships are not always so. Almost all of us have had difficulties in expressing ourselves freely or setting limits ...Read full article...
Is urban life making you crazy?
A study in 1930 pointed out that living in a city increases the risk of suffering from psychosis. Urban life puts mental health at risk in several ways, but there is good news: there are ways to cushion the impact. We like to live in the city. More than half of the planet is currently doing so. It is understandable. Large cities have numerous advantages, among which are that ...Read full article...
Immune System response depends on our biological clock
The immune system seems to be governed by an internal clock that coordinates with our central biological clock. The functioning of the human body, as well as that of plants and other animals, is regulated by an internal biological clock called the circadian rhythm that is synchronized with the night and day cycles. It is formed by neurons of the suprachiasmatic nucleus, located at the base of the brain, ...Read full article...
When it comes to dieting, the Devil is in the details
The way in which you organize your meals and the times you choose to eat are as important as the nutritional value of the food you ingest. Let’s start from the most important point of all: Diets don’t work. What works is having an adequate lifestyle. But if you choose to diet, it is important to at least do it right. In an ideal world, you follow a balanced, healthy ...Read full article...
What is emotional hunger?
Eating is a pleasure, but many centuries ago, it was not the first reason why people fed themselves. The first justification that led a person to eat food was survival. But if we consider what we eat today, and we stop to think carefully about the answer, surely many reasons arise that take a person to a corner beyond being hungry. One of those reasons has a very close ...Read full article...
Antibiotics are making children fat
The growth of obesity has to do with the antibiotics we give to children. The world is of microbes. They have been here for more than 3,700 million years and have had time to colonize every corner of the planet. Although they are invisible, they represent the bulk of the Earth’s biomass. In our interior, we harbor almost a kilo and a half of bacteria from thousands of different species. ...Read full article...
Eating badly kills more people than smoking
Eating badly, be it in the form of few foods or a lot of others, is related to 11 million deaths in the world per year, according to a study published by The Lancet. This figure represents practically one fifth of the 57 million deaths that occur on the planet annually, and is higher than the deaths attributed to tobacco (7 million, according to the World Health Organization, WHO), ...Read full article...
Niños no vacunados NO representan un riesgo para nadie
“La vacunación en sí no es un método seguro ni eficaz para prevenir la enfermedad”, dice inmunóloga de Harvard. A menudo se afirma que quienes optan por no vacunar a sus hijos por motivos de conciencia ponen en peligro al resto del público, y esta es la razón detrás de la mayoría de la legislación para poner fin a las exenciones a las vacunas que actualmente están considerando los ...Read full article...
Eating ‘unsweetened’ and ‘light’ products can cause more strokes and heart disease
For some people, soft drinks with ‘light’ labels are a good choice for health. Others believe that sugarless food might be a good choice to lose weight, but not in the eyes of scientists. According to recent research, which has put the effects of sweeteners under scrutiny, excessive consumption of apparently unsweetened soft drinks could have negative consequences for health. Researchers examined the association between sugar-free drinks, stroke and ...Read full article...
Your home’s air poisoned by cleaning products
Not even inside our homes are we safe from atmospheric pollution if we do not take the proper precautions. Some culinary practices and housecleaning work -especially if we dust or use chemicals- increase pollution levels in cities already considered highly contaminated. This is the main conclusion of a study led by researchers from the University of Colorado in the United States, whose preliminary results presented last month at the ...Read full article...
The “natural flavor” trap in processed food
Pay attention and you will see something strange in the supermarket. Food brands begin to promote their products with claims that are difficult to understand. For example, the already “100% vegetable” idea, the oatmeal drink of a well-known brand is presented to the buyer with two curious words: “natural flavor”. But what does that mean? The truth is that we do not agree on what such a brief message ...Read full article...
The globalization of food production is fertile land for food insecurity
According to the World Health Organization (WHO), foodborne disease affects 600 million people and cause more than 420,000 deaths each year worldwide. Not surprisingly, children take the brunt, both in terms of mortality and developmental delay, which affects nearly 150 million children under the age of five and is often caused by dangerous microbes or parasites that invade their meals. Last year, for example, a lethal outbreak of listeria ...Read full article...
