Issues on Healthy Foods
Dehydrated Foods
Apr 5th
Food drying is a practice used to preserve fruit, vegetables and animal protein to the crop since ancient times, and a dehydrator refers to a device that removes moisture from food to contribute to their conservation. A dehydrator uses a heat source and airflow to reduce the water content of foods. The water content of food is usually very high, typically 80% to 95% for different types of fruit and vegetables and 50% to 75% for different types of meat. The removal of moisture from the food prevents growth of different bacteria and food spoilage. The removal of moisture from the food drastically reduces the weight of the food. For example, to store dry fruit and used to extend shelf life of various foods.
Devices require heat using energy sources like solar or electrical energy and range in the form of large-scale drainage DIY projects or commercial projects for home use sold. A commercial dehydrator essential components usually consist of a heater, fan, so that to create for ventilation and bowls of food. A dehydrator heating, ventilation openings and simultaneously remove moisture from the food. A heating element heats the dehydrator’s so that when the moisture from the inside. The device blows warm, moist air from the unit through the ventilation slots. This process takes hours for the food on a much lower water content, usually fifteen to twenty percent or less dried.
Most foods are dried at temperatures of 130 ° F or 54 ° C, although the meat is processed into jerky to be heated at a higher temperature of 155 ° F or 68 ° C, these temperatures or dried, for protection against pathogens, who may be in the flesh. The key to successful food dehydration is the application of a constant temperature and adequate air flow. Too high a temperature can lead to curing food, that food is hard and dry on the outside but moist on the inside is.
The first commercial dehydrator was sold 1920th Solar dryers use solar energy to make a stream of warm air from the compartment. Solar dehydrator are often cited as a viable tool for the search for sustainable agriculture and food security. Also as an option to supply emergency dehydrated food and water storage for emergency conditions such as in extreme adventure or other nature explorations.
Coffee and Women’s Health
Feb 13th
Sterility
The results revealed that women who drank a cup of coffee every day more susceptible to infertility than women who do not drink coffee. Related Expert had surveyed 104 women who have the habit of drinking coffee, of which approximately 50 people is not easy to get pregnant. In addition there is also a content expert opinion, that this study only small in scope, can not be used as a prove of the special effects of coffee on the birth of a child. However, researchers stress that if it can not explain the causes of sterility in medical science, it must be considered infertility associated with caffeine.
The risk of heart resistance
The experts of medical science from Boston University public health institutions has conducted research for 4 years to 858 women aged 45-69 years of age who first heart infarct disease and 858 women who had never suffered from cardiac infarction disease. The results show, that if every day eat 5 cups of coffee or more, can cause the risk of myocardial infarction in women increased by 70%, after all, the risk will increase and the increase continued in line with the amount of coffee drunk multiply.
Easy caused osteoporosis
Researchers from the University of California, the U.S. has made a survey of 980 women aged between 50-98 twilight years, and the result is found, an old woman who did not consume milk, but drinking more than 2 cups of coffee in the long run, no matter what age and level of obesity, density spine and groin bones will decrease, and the level of decline related to the length of time consumed and the amount of coffee consumed. Therefore, caffeine can be fused with the free calcium in the human body, and excreted in the urine. Decreased calcium-free will definitely cause the decomposition of calcium bind, resulting in osteoporosis.
Not good for the fetus
Since the early 1980s, Doctor Kao Lin from the Agency for the U.S. Food and Drug Administration in an attempt to find, that after feeding rats as much as 12-24 cups of strong coffee consumed adult dose every day, pregnant rats, mice will give birth to children with disabilities . Therefore, on behalf of the U.S. Food and Drug Administration, researchers advise pregnant women should stop drinking coffee for a while.
Syndrome of high blood pressure
This disease is a disease typical of pregnant women, patients manifesting edema (edema water), high blood pressure and urinary with egg whites enzimes, if not prevented and treated immediately, could endanger the safety of the fetus’s mother. An Australian study says that although every day just to drink a few cups of coffee just to raise blood pressure. Therefore, it is not good for pregnant women to drink coffee.
Easily arise diabetes
Survey results and analysis of Finnish and American researchers showed that these two countries is a country whose citizens consume more coffee. Consequently, in these countries who suffer from diabetes is also the largest. Among other things, the number of coffee consumers nation Finland ranks first in the world, and people with diabetes is also the largest country in the world.
The number of coffee consumers in Northern European countries are also quite large, and people who suffer from diabetes too much. In contrast, the number of copies of the Japanese consumer in the world at least, and people with diabetes are also at least. According to the analysis of researchers, that the caffeine in coffee through the pancreas in the composition of the fetus, especially the liver and brain of the fetus, can lead to babies born later might be suffering from diabetes.
