In the play William Shakespeare described at will the 7 stages of life. One hundred years later, science explores these stages of human life in terms of diet and associated changes to help the body achieve its maximum well-being.
Do you eat to live or do you live to eat? With food, we maintain a complicated relationship that affects the cost, availability and even the pressures of our environment. But we all have one thing in common: appetite, that is, our desire to eat.
Recent studies have shown that the abundance of food signals – smells, sounds, advertisements – is a major cause of overconsumption in our environment.
Our appetite is not constant, but changes over time as we grow older As the choices we make regarding food will be a crucial factor in health and well-being in our lives, it is important that we apply the right habits.
To rewrite Shakespeare, one could say that there are such "Seven Years of Life" appetite and a better knowledge of these phases will help us to find new ways to deal with the problems of poor nutrition and over-consumption, and in particular the resulting Health Effects of Overweight
First decade, from 0 to 10 years
In early childhood, the body experiences rapid growth. The eating habits acquired in the early stages of life can sneak into adulthood, turning a fat child into a fat adult.
Food-related fears can change the eating time in a real fight for the parents of small children; Implementing a strategy that repeats tasting and learning in a positive environment can help children to know foods they are not used to, but which are very important, such as: Vegetables.
Children should be able to exercise some control themselves, especially with regard to portion sizes. The fact that parents force them to "leave the plate empty" can lead to children losing the ability to pay attention to their own signs of hunger and appetite, leading to overeating at a later date.
Governments are increasingly demanding that babies be protected from junk food advertising – not just on television, but also in applications, social networks and video blogs – as certain foods increase in popularity and encourage obesity ,
Second decade, from 10 to 20 years
In puberty, the increase in appetite and height driven by hormones indicates the arrival of from puberty to transition from childhood to adulthood.
The relationship that a teenager has to eating at this crucial time will determine his lifestyle in later years. This means that the nutritional choices that adolescents make are closely related to the health of the generations they will produce in the future. Unfortunately, if they are not given guidance, young people may adopt dietary habits and consumption preferences that are usually associated with unhealthy consequences.
More studies are needed to find the most effective way to tackle the growing burden of malnutrition and malnutrition. in particular their relationship with poverty and social inequality.
In general, young women are more likely to suffer from nutritional deficiencies than young men because of their reproductive biology. Pregnant teenage girls are also at greater risk as their organism supports their growth and that of the growing fetus.
Third decade, from 20 to 30 years
When we reach young adulthood, lifestyle changes can lead to weight gain. For example, having a college visit, marrying or living with a partner and having children.
Once accumulated, body fat is often difficult to lose: the body sends strong appetite signals to eat when we consume less than we need, but the signals that prevent us from overeating are weaker, what can result in a cycle of excessive consumption. There are many physiological and psychological factors that make the tendency to overeating too light over time too easy.
One area that has recently aroused interest in research is the development of satiety or the feeling of having eaten. enough. This spring is useful when we are trying to lose weight because the feeling of hunger is one of the major difficulties we face when trying to eat less than the body says it needs, ie when we have a "calorie deficit."
Different foods send different signals to the brain, such as eating ice cream, because fat does not send signals to the brain to stop eating, and protein, water and fiber rich ones instead Foods the ability to make us feel full longer The collaboration with the food industry gives us the opportunity to discuss the future of meals and snacks in an advantageous way.
Fourth decade, from 30 to 40 years
Working life in adulthood poses other difficulties: not just the borborigmotic or abdominal ger NOISE, but also the effects of stress, which, as shown at 80% of the population leads to changes in appetite and eating habits.
They can both trigger an insatiable appetite and cause an appetite loss. The different strategies to tackle this problem are attracting a great deal of attention: the phenomenon of "food addiction" – the irresistible need to consume certain foods that are often high in calories – is poorly understood, and many researchers even doubt its existence
There are others Personality traits such as perfectionism and meticulousness, which can also affect stress management and eating habits.
Structure the work environment to reduce problem eating habits like vending machines It's a challenge to face with food and snacks. Employers should strive to subsidize and promote healthier food if they want to have a productive and healthy workforce, paying special attention to the way they deal with stress and the situations that cause it.
40 to 50 years
We are customs animals and do not want to change our habits, even though we know that this is for our own benefit.
The word diet comes from the Greek term diaita and means "life regime, way of life". However, we want to eat as much as we want without changing our lifestyle and yet we want to have a healthy body and mind.
According to numerous data, improper nutrition is one of the main factors contributing to a poor diet Health The World Health Organization stresses that smoking, unhealthy diet, physical inactivity and alcohol problems are the lifestyle factors that most affect health and mortality.
Years when adults need to change their behavior due to health needs, but the disease symptoms are often invisible – such as high blood pressure or high cholesterol levels – and there are too many people who take no action to resolve them.
Sixth decade, from 50 to 60 years
In this age group, the progressive loss of muscle mass starts at between 0.5% and 1%. Annually from 50 and steadily farther, the older we get become. This phenomenon is called sarcopenia.
Factors such as decreased physical activity, consumption of less protein than necessary, and menopause in women accelerate muscle breakdown.
Healthy and varied diets and physical activity training are important to reduce the effects of aging; Older people, however, see no need for protein rich, tasty and cheap foods. High-protein snacks are an ideal opportunity to increase total protein intake in the elderly. However, there are currently only a few products that meet the needs and preferences of this age group.
Seventh Decade, 60 to 70 Years and More
An important difficulty in increasing life expectancy today is maintaining the quality of life because otherwise we become a society of very old and sick or disability affected people.
Proper nutrition is important as aging leads to loss of appetite and hunger, leading to unwanted weight loss and increased fragility. A decreased appetite may also be a consequence of a certain disease, such as Alzheimer's disease.
Food is a social experience, and there are factors such as poverty, loss of a partner or relative, and the fact that one eats without companionship, which affects the sense of pleasure that comes with eating.
Other effects of age, such as dysphagia, dental problems and loss of taste and smell (no teeth) […] no taste, says Shakespeare!), Also affects the craving to eat and the benefits we derive from this practice.
We should remember that our diet is not a mere fuel throughout life. But a social and cultural experience that gives pleasure.
We are all food experts: it is an activity that we practice every day. Therefore, we must strive to consider each meal as an opportunity to enjoy our diet and to take advantage of the beneficial effects of eating adequate foods on our health.
