Fat has 38.1 kJ per gram and has by far the highest energy content. The term "joule" comes from the English physicist JP Joule that indicates the energy required to increase the temperature of 1g of water by 1 ° C. 1,000 joule equals 1 kilojoules (kJ). In everyday use, however, the more common unit is the kilocalorie (kcal). Where: 4.184 kJ = 1 kcal .
Thus, fat has a calorific value of 38.1 kJ = 9.1 kcal. By comparison, proteins and carbohydrates provide just 17.1 kJ (4.1 kcal) per gram. Even alcohol is 29.3 kJ (7.1 kcal), under the energy content of fat.
To burn now 1 kg of body fat, you would first have to identify the physiological calorific value (energy content) of 1 kg human adipose tissue. If we extrapolate the physiological caloric value of fat to one kilogram, we get about 38,100 kJ, equivalent to 9,100 kcal. But, does one have to save 9,100 calories to lose one kilogram of body fat? No. Since the human adipose tissue is not 100 percent pure fat, but about 25 percent water, which is the physiological caloric value of body fat "only" is about 6,900 kcal.
To lose a kilogram body fat, you must thus save around 7,000 calories. With the aim to lose one kilogram of fat in a week, that would be 1,000 calories per day. This is not an easy task and even not recommended. But what is the best way to proceed? Eat less? Or just move more?

The proper functioning of the immune system basically depends on three factors: the environment, food and emotional health of the child or adult. A malnourished child or a kid in a toxic environment or with a serious emotional problem has higher risk of getting sick. It is therefore appropriate to demystify the whole market of natural or synthetic products that promise a stronger immune system: nutritional supplements, vitamins, royal jelly. They won't help if we do not take care of the basic pillars that guarantee good health.
Nature has given us a wonderful way to strengthen the defenses of the baby at birth gift: breast milk.

Breast milk acts like a natural vaccine, passing, passively, the defenses that the mother has the breastfed child. The protective effect of breastfeeding against respiratory diseases, gastrointestinal, obesity, diabetes and leukemia, is amply demonstrated.
For its proper functioning, our body need a proper supply of nutrients from the diet, not supplements or artificial foods. Children should eat plenty of vegetables and fruits of all colors daily (each color represents a nutrient, vitamin antioxidant or different), whole grains and legumes. Furthermore, their nutrition should provide quality protein: egg, poultry and fish are essential to ensure proper growth and development. Sugars, sweets, biscuits or artificial juices should not abound in a baby diet because of large amount of sugar, salt and saturated fats.
The houses should be aired daily, to maintain a fresh, clean air. Field trips, outdoor activities ... in some contaminated sites are beneficial for children. On the other hand, it should be adequate hygiene, not excessively or not deficient, since both ends favor the child to get sick more than usual.
For proper physical development, emotional health is fundamental. Let the kids be kids: playing time, adequate rest and feeling loved and accepted are the keys to their welfare. If the child is happy, he is more likely to enjoy good physical health.
The high levels of LDL cholesterol are one of the major health problems affecting many people in the world. A lot of information indicating that high levels of LDL cholesterol are associated strongly with the risk of coronary heart disease. When LDL cholesterol levels are high, cholesterol is deposited in the walls of arteries and forms a hard substance called plaque. Over time, the plaque causes the arteries to narrow, reducing blood flow and causing a condition called atherosclerosis, which can lead to the occurrence of serious cardiovascular problems.
In this article, we show you 5 of the most beneficial food and supplements to maintain healthy cholesterol levels based on this reference:
Fruits contain many vitamins and essential nutrients, and therefore their consumption is very beneficial to our health, growth and human development.
Vitamin A is present in many fruits, the most noteworthy include oranges, blackberries, watermelons, peaches, apples and kiwis. The benefits that this vitamin our body gives us are cell reproduction, the formation of hormones, stimulating the immune system and improvement of vision and hair growth.
Vitamin B1 can be found in bananas, raspberries, pears, lemons, oranges, mangoes, grapefruits and pineapples. The benefits that this vitamin contributes to our health are the proper functioning of the heart, nervous system and muscles.
Vitamin B2 can be found in the kiwi. This vitamin is necessary for production of red blood cells, growth, physical development and reproduction.
We can find vitamin B3 in bananas, peaches, kiwis and melons. This vitamin is important for the proper functioning of the digestive system and the nervous system, for healthy skin and normal growth.
Vitamin B5 can be found in fruits such as oranges and bananas. This vitamin brings us many benefits to our health, most notably the metabolism of food, cholesterol production, manufacture vitamin D and steroid hormones and maintaining a healthy digestive system.
Vitamin B6 can get the bananas and watermelons. This vitamin is necessary for the metabolism of carbohydrates, fats and proteins, for the production of antibodies, the immune system maintenance, the production of red blood cells and the proper functioning of the nervous system.
In vitamin B9 and folic acid we have folate and can be found in strawberries, kiwis, blackberries, oranges and bananas. This vitamin is necessary for cell growth, fetal development, the production of red blood cells, DNA and nervous system.
Some of the most important vitamins are found in fruits and vegetables, so it is important to know the best way to preserve their vitamins. Some ways to help save the vitamins of fresh fruit is, in case you need to cook, is simmering them. Just cut the fruit parts beaten. If possible, consuming the fruit skin, that is, in the case for example apples and pears. If it is necessary to peel the fruit, you should eat as soon as possible. The air oxidizes the fruit, vitamins start to break down. It is important to keep fruits in a cool place, it helps to preserve vitamins. Frozen fruits tend to have better nutrients because of low temperatures and lack of exposure to air.
