Food Preservation

While we consider some historical data, we know that conservation of the food itself, regardless of cultural and period in which people live, has been an obsession and constant concerns in human history.

As early as the Neolithic, for example, and as has been endorsed by hundreds of researchers, it became known that the cold would be for food preservation, to keep them in good condition, but it was not until Napoleon in the nineteenth century – conducted a campaign to encourage research in this field when it was discovered that the oil was a special and useful item for the conservation of fish.

With all this, and many efforts, was born the food canning process on glass, but then the Englishman Peter Durand kept making new containers turn a new material: tinplate, which allowed the thought lasted longer and the container itself was much stronger.

And so, after much research, and “years” of experience, today it is known that the conservation process does not alter the nutritional composition of foods, keeping them intact.

For example, light-sensitive nutrients such as vitamins K, A and folic acid is not lost with the passage of time by not giving the light itself to the contents of the can.

For many fish, oleic acid oil used for coverage and conservation features cardiovascular properties, preventing heart disease.

Eat broccoli to improve skin health

According to the study presented at the annual meeting of the American Society for Cell Biology in Washington, the natural compound sulforaphane, abundant in broccoli and other vegetables would influence the treatment of genetic skin disease called epidermolysis bullosa simplex.

Epidermolysis bullosa simplex is a genetic disease that weakens the skin and causes it to break easily by a slight bump or friction, such as scratching.

Signs and symptoms are variable, can affect the hands, feet and heels, or in severe cases, the breakdown of the skin in much of the body generates infections, dehydration and even death in infants.

Dr. Pierre Coulombe, School of Medicine, Johns Hopkins University in Baltimore, noted that most cases of epidermolysis bullosa simplex due to mutations in the genes that encode the proteins keratin 5 (K5) or keratin 14 (K14), which are skin cells.

The researcher explained that the use of topical sulforaphane to treat the disease takes a functional redundancy in the keratin gene family.

When mice were treated with sulforaphane showed a significant reduction of the breakdown of the skin, since this substance can activate two keratin genes, whose sequence and properties are closely related to one of two defective genes of keratin in epidermolysis bullosa simplex .

That is, treatment with sulforaphane promotes the production of skin cells that reduce the breakdown caused by the lack of K14 in the mouse model. The authors claim that sulforaphane and similar drugs are options to prevent the breakdown of the skin associated with K14 mutations in this disease.

Coulombe hopes that in future sulforaphane treatment or is the main component of treatment for patients with the disease, as currently available treatments relieve symptoms but not cure the condition and have limited effectiveness.

While already obtained some evidence that when applied to human skin sulforaphane compound induces the correct genetic types of keratin, the team is taking the first steps to bring these results to patients.

Finally, note that the sulfurafano also may enhance detoxification of undesirable compounds and strengthen cellular antioxidant defenses. In addition to get from broccoli, can be found in cauliflower, cabbage, cabbage and radish. All these vegetables are “functional foods” because they contain a substance that promotes our health.

Cooked foods increase the risk of uterine and ovarian cancer

A Dutch study of more than 120,000 people a direct relationship between consumption of acrylamide, compound formed when heating food, and the incidence of uterine and ovarian cancer.

Acrylamide is generated in processed or cooked foods such as bread, breakfast cereals, coffee, meat and fried or baked potatoes.

Research indicates that women who absorbed more acrylamide were twice as likely to suffer these types of cancer than others.

The study conducted in Dutch University of Maastricht, said that the amount of acrylamide than twice the incidence of cancer is equivalent to the daily consumption of a packet of chips or half a pack of biscuits per day.

Experts recommend eating foods cooked at home, as they typically contain smaller amounts of this substance that processed products and food that is served in fast food establishments and even in restaurants.

I would add that the food purchased is not only more risky and have higher amounts of acrylamide, but also possesses a higher amount of calories that the food prepared by our own hands.

Notwithstanding these recommendations, knowledgeable on the subject acknowledge that it is impossible to completely eliminate the acrylamide in food.

Food is a strategic factor in the life of a competitive athlete. It plays an obvious role in improving performance, but it is invaded by energy and protein supplements to the effects not always controlled.

Meal Assembly
Feeding the athlete differs little from that of everyone. It should be composed especially better, eaten at the right time and in greater quantity, ensuring reconstruct losses of water and minerals through sweating.

Power Sports Foods

Carbohydrates are the fuel core muscles and should be absorbed in large quantities (pasta, potatoes) on a regular basis during training and a few hours before competitions (three or four hours before). Always prefer the sugars contained in the pasta and starches to sugars pastries and sugary drinks.

Protein is important for the renewal of muscle growth and iron intake, as well as lipids, which provide vitamins and fats needed for the proper functioning of the body.

Finally fruits and vegetables provide vitamins and minerals and their water intake and promote rehydration.
Yoghurt and other dairy products, daily absorbed also involved in the supply of protein and calcium needed for bone and muscle contraction.

Diet
If the diet of an individual who has a normal activity, is approximately 2000 kilocalories (kcal), it can be significantly increased in the great sport, because of the enormous energy consumption required in some effort. A stage of Tour de France may require a diet of about 10 000 kcal, due to the intensity and duration of the event.

For all athletes, it is important to have a balanced diet, suited to the effort, focusing on natural foods and easy to digest. Avoid meats such as sauces and fried foods that may be responsible for cons-performance during training and tests.

Water
Hydration of the sportsman is fundamental, and often obeys modes. For example, in the years 1950-60, it was recommended in the marathon to not drink during the race, but now we must drink several liters of water. It is estimated that the loss of 1% of body weight in water leads to a decrease of 10% of athletic performance. The drink is so important and its volume must be adapted to stress, climate and the duration of the effort.

The important thing is to drink regularly in small quantities, without waiting for the sensation of thirst or fatigue.

Supplements
Nutritional supplements are the subject of constant controversy. A few years ago, the fashion was to supplement carnitine, sensible increase muscle mass. Now it is creatine, which is known about the long-term effects, even if it has a significant effect on muscle performance of short duration, the type of sprint. Creatine (instead of carnitine) is not prohibited and is not considered a doping product.

Energy drinks are rich in minerals, salts and vitamins are of interest to reconstruct metabolic control during exercise, but some of these drinks are fortified with amino acids such as taurine, whose effects are not all known, and which are banned in some countries like France.

The timing of food is a ritual, which many consider one of the great pleasures of life, which is why it is necessary to take our time and enjoy those hours around food.

For it is important that we take time before and organize in advance the times in which we must nurture, because when our bodies stay healthy, you should not skip the meal times, which can bring a result a lack of nutrients in our body, which attempt to compensate for missing lunch the next time we go to eat.

Feeding times should be respected from an early age, school age children, adolescents and elderly, who are the most nutrients needed in the body as food is concerned with putting the body in motion and provides the energy needed then of hours of rest.

There are many scientific studies that say that breakfast is one of the most important meal of the day, and he did not skip it help you lose weight and keep healthy, so at times when making food, whether we have this 3 meals major and two snacks, or 6 small meals a day, the best in all cases is quite healthy food choices, rich in vitamins, minerals, carbohydrates, and not skip any, that the body is satisfied over day without exceeding it.

Life is a matter of priorities, and priority should be taking care of our body. Not just to have a healthy appearance, but also to maintain acceptable levels of quality of life. Therefore, we must be aware of the importance that the practice of physical activity has on our daily lives.

1In physical activity benefit sometimes wait for a doctor to give us the alarm to improve physical activity a physiological imbalance (diabetes, hypertension, etc …)

But … why wait to have a problem to put solutions? Why not put the means to prevent potential problems in our bodies from an early age without waiting to develop? The sooner we start our life healthy activities, we will have more chances to enjoy a full and active life.

Antibiotics are very useful medicine that have saved countless lives, but have their drawbacks. They are very effective in killing bacteria but are so powerful that kill all bacteria, including those that are friendly to our body.

In the intestine there are many types of bacteria that are essential for the proper functioning of the intestine. In this population of “good” bacteria is called intestinal flora.
