If you want to eat healthy, you only know that scientific nutrition is not enough. It is also one of the necessary capabilities to see through the secrets of the processed food industry. A number of US food expert opinions interview domestic nutrition experts to unveil the 10 secrets that are common in the food industry.
Don't believe that cookies are healthy. Wei Liping, director of nutrition at the Hospital of Integrated Traditional Chinese and Western Medicine, Southern Medical University, said that biscuits contain refined grains, fats, salt, sugar and other substances, and long-term consumption can easily cause excess energy. During high temperature processing, B vitamins contained in food ingredients are destroyed. Relatively speaking, whole-wheat crackers are relatively healthy, but it is rare that they can really achieve less oil, less salt, and lower sodium in the market.
"High fiber" may be counterfeit. American food expert Dr. Robert Davies pointed out that chicory root or maltodextrin can create the illusion of "high cellulose." Compared with natural dietary fiber in cereals and vegetables, this type of so-called "high-fiber" food not only does not bring health, but may also cause abdominal distention, suffocation and other gastrointestinal problems. Wei Liping reminded that to supplement dietary fiber should choose fruits and vegetables or coarse grains, edible fungus such as fungus, mushrooms, and kelp are also relatively abundant.
Extra virgin olive oil may be a steamed bread. Olive oil is considered to be a healthy oil. Its advantage is that monounsaturated fatty acid content is high, accounting for 86% of the total fat, which helps reduce blood fat and prevent vascular diseases. However, Wei Liping believes that due to the fact that the total energy intake of modern people exceeds the standard, it is hoped that the goal of reducing lipids and preventing diseases by replacing edible oils may have little effect. Not only that, but now the olive oil market is turbulent. A survey conducted by Prof. Dan Flynn of the Olive Center of the University of California, USA, found that about 70% of the olive oil on the market does not meet the criteria of extra virginity (not more than 1% acidity). Therefore, from a cost-effective point of view, it is better to choose domestic soybean oil, sunflower oil, and pay attention to the control of oil consumption.
"Natural" is misleading. If a cooked meat product says "Natural" or "Preservative free (Sodium nitrite)" on the label, you may feel very relieved. Dr. Joseph Seblanek, professor of meat science at Iowa State University in the United States, cautioned that this may also be misleading. For example, the labeling of meat products containing “celery meal and active bacterial cultures†can naturally synthesize sodium nitrite and play a certain antiseptic effect. It is not recommended to consume large amounts of food in the long term.
Organic foods do not necessarily equal health. “Organic†does not necessarily mean “healthyâ€. Prof. Shaxi Bruce, a food safety expert at the University of Illinois at Urbana-Champaign, explained that organic foods absolutely prohibit the use of pesticides, fertilizers, herbicides, etc., as well as soil, air, and water environment. With high demands and relying on current scientific methods, whether or not to meet organic standards is difficult to detect and can only rely on the trust of producers and regulators. Experts pointed out that at home, it is actually the certification of “green food†and the complete supervision process. The regular sampling system is perfect and the quality is relatively reliable.
Use "reduced" sugar content with a pseudonym. Walter Willett, head of the Department of Nutrition at the Harvard School of Public Health, reminds that in many processed foods, companies will use sugared cane juice, agave nectar, fruit juice concentrate, and corn syrup to replace “sugar†â€, causing the product to have no illusion of less sugar or sugar. The U.S. Food and Drug Administration (FDA) has now asked manufacturers to list all sugar additives on the ingredient list. Consumers need to pay more attention.
