4 things that secretly harm your health

The things we come into contact with every day in our lives are actually secretly harming your health, but you just don’t know it. If you always ignore the harm of these things, sooner or later you will regret it!

1. The water you drink from the tap may contain excessive lead

Beijing faucet product inspection: only 2 out of 50 types were lead-free

The Shanghai Consumer Council once found in a comparative test of faucet products that 22% of the samples tested had excessive lead levels, and some products exceeded the standard by 20 times. The Beijing Consumer Association tested 50 faucet products randomly purchased from various markets in Beijing and found that in the 10-hour and 24-hour lead precipitation concentration tests, only two stainless steel samples had no lead precipitation at all.

Where does lead pollution come from? The source is the material of water pipes and faucets

The faucets used in most households are still cast iron or copper alloy. The main components of copper alloy faucets are copper and zinc, in addition to lead, aluminum, tin, iron, manganese and other elements. The lead element will precipitate after long-term contact with water. The more lead content in the faucet material, the more lead will precipitate. In addition to faucets, cast iron pipes, copper pipes and plastic pipes also contain lead to varying degrees. If these materials are used in water pipes, it will also cause lead pollution problems.

Lead affects children's height and IQ development and causes irreversible brain damage throughout life

Data show that for every 100 micrograms/liter increase in blood lead levels, a child will grow 1-3 centimeters less in height. If blood lead levels rise by 100 micrograms/liter, a child's IQ will drop by 6-8 points. Lead can cause damage to multiple organs and systems in children, and the damage to the brain can even be irreversible throughout life.

① When the tap water is out of use for more than 6 hours, be sure to open the tap and let the water run for more than 1-3 minutes before drinking;

②Now many families have hot water supply, but it is best not to use it as drinking water or cooking, because the lead content in hot water is many times higher than that in cold water;

③When purchasing a faucet, be sure to choose a product that meets quality standards, and it is best to choose a faucet made of stainless steel.

2. Crispy foods are the killer of cardiovascular disease and cancer

The problems with crispy foods mainly manifest themselves in four aspects: refined carbohydrates, trans fatty acids, the carcinogen acrylamide and various additives.

Crispy foods are mostly made by baking or frying. Hydrogenated oil or partially hydrogenated shortening is used in the processing, which contains trans fatty acids to some extent. The molecular structure of trans fatty acids is distorted, making it difficult for the human body to digest and absorb. As a result, it will increase triglycerides and bad cholesterol in the blood and decrease good cholesterol, thereby increasing the risk of cardiovascular disease.

Businesses favor hydrogenated oils because it not only prolongs the shelf life of products, thereby extending their sales period, but also makes food crispier and more delicious. More importantly, hydrogenated oils containing trans fatty acids are low-cost. Acrylamide, also known as "acrylamide", is a carcinogen. It is commonly found in crispy foods made by frying or baking.

Yu Kang, deputy director of the Department of Nutrition at Peking Union Medical College Hospital, pointed out:

Frequent consumption of crispy foods will increase blood lipids, lead to obesity, and increase the incidence of cardiovascular and cerebrovascular diseases, diabetes and other diseases.

3. Cooking fumes are the culprit for the increasing incidence of lung cancer in women

Women who cook for a long time and are exposed to high temperature fumes have a 2-3 times higher risk of lung cancer

According to a five-year epidemiological survey on lung cancer recently published by the Shanghai Institute of Oncology, young and middle-aged women who are exposed to high-temperature fumes while cooking in the kitchen for a long time will increase their risk of lung cancer by 2-3 times. The damage caused by oil smoke to the lungs usually leads to chronic bronchitis, emphysema and lung cancer. Lung cancer occurs because of the oil fume particles produced by high temperatures. These particles, which are smaller than 0.01 microns, are inhaled into the lungs through the respiratory tract, penetrate deep into the lungs, and combine with the cell membranes of the alveoli to generate oxygen free radicals, which in turn damage the genes of the lung cells, induce gene mutations, and lead to lung cancer. The higher the temperature of the oil, the greater the danger, and a bad home environment and cooking habits are also accomplices.

Use steaming or boiling instead of frying to install exhaust equipment to help

It is recommended to use steaming, boiling, slow braising and other methods instead of frying, stir-frying and high-temperature frying. Otherwise, don’t wait until oil smoke rises before putting the food into the pan. Try “water frying” instead. Add some water to the pan halfway through frying and cover the pot with a lid to reduce the chance of oil smoke spreading into the air. In addition, installing exhaust equipment in the kitchen and lowering the height of the range hood can also allow the fumes generated during cooking to be directly sucked into the range hood, which is a good way to avoid inhaling fumes.

4 major handbags that can hurt your lumbar spine

Guo Xianfeng, director of the Rehabilitation Department of Beijing Jishuitan Hospital, said that office women are a high-risk group for lumbar and cervical spine problems due to the characteristics of their jobs such as using computers and working at desks. Now more and more women are accustomed to putting laptops, mobile phones, cosmetics, etc. into large handbags, which makes the lumbar spine of professional women even more overwhelmed.

The human spine is like a tower crane. If the left side is loaded with weight, the spine will bend to the left. In order to maintain the balance of the spine, the muscles on the right side of the spine will actively contract. Due to the difference in lever arms on the left and right sides, the muscles on the right side will produce several times the force of the left side (like the relationship between the long arm and short arm of a tower crane). If you carry a 5 kg weight on your left shoulder, the muscles on the right side may have to generate 15 to 20 kg of force to maintain your body's balance. This force will eventually compress the lumbar spine. In addition, wearing high heels frequently will accelerate the aging of the waist and back over time.

If there are heavy objects in the bag, the force should be balanced.

Doctors suggest that women who like to carry large handbags must adopt the correct way of carrying the bag if they really cannot "reduce the burden". They should keep their bodies straight and their heads and shoulders basically "upright".

You can hold heavy objects in front of your chest, or use a backpack to keep the weight close to your spine so that the force is evenly distributed. If you carry a handbag, it is best to balance the weight with both hands and tighten your anus and abdomen while walking. If you only have a heavier handbag, it is best to carry it with both hands alternately. If you carry a crossbody bag with a longer strap, it is best to place the bag on your abdomen instead of on both sides.
