Have a unique interest in "all-natural"? Pure natural is not necessarily good!

Do you have a unique interest in "all-natural"? In a recent commentary published in the British journal Nature Human Behavior, everyone has a belief in being "close to nature". Naturality is defined as "not man-made and does not involve anything made or caused by man; It is widely believed that nature is where human well-being lies, and once an object is considered natural, consumers infer other attributes, such as safety and health, while non-natural man-made chemicals are hated as "not safe or healthy enough". Experts say "all-natural" is not necessarily good and is often a gimmick in commercial marketing.
natural food, the source is unknown and easy to poison. When it comes to all-natural foods, we all think of "green", "organic", "pollution-free" and other words, "organic fruits and vegetables", "pure natural honey", "pollution-free ecological eggs" and other products have higher prices than ordinary food. Yun Yun, Ph.D. in Food Engineering, Department of Agriculture and Bioengineering at Purdue University in the United States, said it is unrealistic to eat food without any human intervention without a definition of "all-natural" in the food sector.
food safety classification, food divided into ordinary food, pollution-free food, green food, organic food four levels. Among them, the minimum standard of ordinary food, allowing the application of regulations to limit the range of types and added amount of fertilizer, pesticides, livestock feed, organic food standards are the highest, in the production process do not use pesticides, fertilizers, growth regulators, antibiotics, genetically modified technology, but also use organic fertilizer and bio-source pesticides. The so-called pure natural food, because there is no standard, in the planting, harvesting, storage and preparation process lack of strict quality control, some even unknown sources, such as wild bacteria, wild animals, casual consumption may lead to poisoning, safety can not be guaranteed. Whether it is livestock fish, or fruits and vegetables, in order to less pests, bacteria, etc. , all need to take the necessary intervention. And to meet the food regulatory standards of formal food, agricultural residues exceed the standard is very small, the relevant departments issued a test report shows that in recent years, a variety of ingredients are mostly qualified rate of about 98%. If we are really worried, through tap water cleaning, peeling, water and other ways can effectively remove agricultural residues.
natural cosmetics with a short shelf life and an allergy risk. Open an e-commerce website to search for "homemade skin care products", you can see thousands of products on display, from face wash, toner, moisturizing cream, to mask, lipstick and so on. There are merchants declared that "no preservatives, the use of natural herbs made purely by hand", such as gold and silver flowers, roses and so on. In fact, the China Consumer Association has rejected cosmetic advertisements such as "100% all-natural" and "chemical-free addition" - all-natural cosmetics do not exist.
China Spice Flavor Cosmetics Industry Association and other institutions jointly issued the "whitening beauty skin care products consumption guidelines" introduced, usually, cosmetics are made from a variety of ingredients including chemical distribution, of which the largest proportion of the composition is often deionized water, depending on the product type may add other ingredients, such as glycelin, white oil, silicone oil, stingric acid, nutrients, flavor, preservatives and so on. In contrast, natural plant ingredients are only a small part of them, and pure natural plant ingredients cannot be made into products. Liu Yongsheng, director of dermatology at China Medical University's Aviation General Hospital, said that the current network as a sales channel for those "all-natural" cosmetics, directly add petals and other plants, itself easy to lead to bacterial growth and product corruption, if no longer add preservatives, its service life is very short. In addition, these products have not been rigorously clinically tested to determine whether there are sensitive substances or other chemicals in the ingredients. Some so-called "all-natural" cosmetics, in order not to let customers after the use of allergies and other symptoms, secretly add hormones and other ingredients, may lead to hormone-dependent dermatitis and other side effects. In addition, fruits and vegetables directly applied to the face, sensitive skin people may cause irritation, redness and other allergic symptoms, and some photosensitive fruits and vegetables (citrus, mango, celery, spinach, etc.), direct contact with the skin, and then encounter sunlight, may cause sun dermatitis, resulting in facial redness, papules and blisters and other symptoms.
all natural fabrics, although there are advantages but not all aspects are good. People have been exposed to cotton, hemp, silk, wool and so on in their daily lives are common raw materials for all-natural clothing fabrics. Because most finished clothing products need to go through the process of pulping, dyeing and so on, so clothes in the advertising campaign with "all-natural" as an advertising language is not very appropriate. But in the inherent impression, natural fabrics are often better by default than synthetic fabrics. Tao Wei, a professorial senior engineer at the China Society of Textile Engineering, said that "pure natural" fabrics are not the best, in fact, most brands on the market are mixed fabrics, even functional fabrics, such as single guide wet fabrics, flame retardant fabrics, anti-static fabrics.
all kinds of fabrics have their advantages. Natural fabrics, cotton sweat absorption, silk smooth, hemp breathable, wool to keep warm. The most common synthetic fibers are polyester, acrylic, spandex, etc. , this fiber is often better color, more wear-resistant, has its own advantages, and with the development of technology, greatly improved the synthetic fiber breathable and other shortcomings. The other is the blended fabric, that is, natural fabrics and chemical fibers in accordance with a certain proportion of mixed weaving, concentrated on cotton, hemp, silk, wool and chemical fiber advantages. In order to ensure the health and safety of clothing fabrics, we should pay attention to the following two points when choosing: 1. Buy qualified products. Qualified products have "execution standards" and "grades" on the label, in line with the standard clothing in formaldehyde content, color fastness and other aspects of protection; 2. Choose fabric according to demand. Underwear, underwear and other best cotton or cotton mixed spandex fabrics, elastic and breathable, coats, etc. can choose some fiber, blended fabrics, not easy to wrinkle, wear resistance;
