2. Provide some suggestions on food health.

Should we choose healthy food or what is healthy? The dietary grain "miscellaneous grains" in China is healthy, and the crops referred to by "five grains" are wheat, millet, millet, millet and hemp.

When it comes to a balanced diet, we can't help but mention the nutrition pyramid; Nutritionists divide foods into four categories, namely, fat and sugar, dairy products and meat, vegetables and fruits, and cereals. The bottom of the nutrition pyramid is mainly cereals, but which agricultural products or foods should belong to cereals?

Rice and wheat are still the main foods in China. In China, rice (rice) cultivation originated in the Shennong era in southern China about 4,700 years ago. The cultivation of wheat (barley and wheat) was introduced into North China in the late prehistoric period or before Pan Geng moved to Yin.

As for the millet, millet and grain in the grain, they all belong to "millet". "Millet" is one of the important grains in the north, and it is rarely planted in the south. "Small" basically includes millet and millet.

Millet is not what we often eat today, but rice seeds and yellow rice. Corn is a crop introduced from the west only in modern times.

Peas are beans, and beans in grains are not all beans, but soybeans. Soybean was called glutinous rice in Zhou Dynasty, and it was called bean since Qin and Han Dynasties.

Hemp in grain refers to hemp. The seeds of hemp are nontoxic, but the leaves are toxic, so it can be used as food.

Calculate the consumption of household food, determine the purchase plan, and then purchase, record the variety, quantity, price and other data of the purchase. After one month, the consumption and surplus of all kinds of grain will be counted, and the grain purchase plan for next month will be revised. Yesterday, Kunming's "Saving Grain at My Side-2008 Youth Scientific Investigation Experience Activity" was launched, and the above series of theme activities will help young people establish the awareness of saving grain.

The youth scientific investigation experience activity is a national theme science popularization activity jointly sponsored by the Ministry of Education, the Central Civilization Office, the State Administration of Radio, Film and Television, the Central Committee of the Communist Youth League and the China Association for Science and Technology. Every year, related activities are organized for young people all over the country around a theme. Following "energy saving is at my side" and "water saving is at my side", this year, under the background of global concern about food issues, the theme of the event was determined as "saving food at my side".

The reporter learned that the activities include special lectures and inspection experiences. On the basis of teenagers' learning and understanding of China's grain problem, we will carry out corresponding scientific investigation and experience activities around saving grain, and carry out experience investigations such as small reporters, propagandists, theme class meetings and farm trips with families, groups and classes as units.

Teenagers will, with the cooperation of their parents, measure the consumption of family food and determine the purchase plan. Then go to shops and vegetable markets to buy in person as planned, and record the variety, quantity, price and other data purchased. After one month, the consumption and surplus of all kinds of grain will be counted, and the grain purchase plan for next month will be revised. Family investigation experience can not only educate teenagers, but also drive other family members to pay attention to saving food together.

In addition, under the organization of the school, teenagers will design and calculate the weight of a grain of rice by themselves in groups of 3-5 people, which has a personal feeling of saving every grain of rice. Plan the investigation activities of saving grain, and collect tips for saving grain through investigation. At the same time, go deep into communities, streets, parks, schools and other places to publicize and save food to the public.

However, through students' personal experience, investigation and publicity, it is helpful for students to establish the awareness of saving food and gradually develop the habit of saving food in daily life.

5. Food safety knowledge

Food safety knowledge:

1, don't believe that cookies are healthy.

Wei Liping, director of the Nutrition Department of the Hospital of Integrated Traditional Chinese and Western Medicine of Southern Medical University, said that biscuits contain refined grains, fat, salt, sugar and other substances, and long-term consumption can easily lead to excess energy. In the process of high temperature processing, the B vitamins contained in food raw materials will be destroyed. Relatively speaking, graham crackers is relatively healthy, but few people in the market can really achieve less oil, less salt and less sodium.

2. "High fiber" may be fake.

Dr robert davies, an American food expert, pointed out that chicory root or maltodextrin can create the illusion of "high cellulose". Compared with pure natural dietary fiber in grains and vegetables, this so-called "high fiber" food can not only bring health, but also cause gastrointestinal problems such as bloating and belching. =

3. Extra virgin olive oil may be a gimmick.

Olive oil is considered as a healthy oil. Its advantage lies in the high content of monounsaturated fatty acids, accounting for 86% of total fat, which is helpful to reduce blood lipid and prevent vascular diseases.

Because the total energy intake of modern people exceeds the standard, it may not be effective if we hope to achieve the purpose of reducing fat and preventing diseases by replacing edible oil. Not only that, the olive oil market is very chaotic now.

Professor Dan Flynn of the Olive Oil Center of the University of California, USA, found that about 70% of the olive oil on the market does not meet the standard of extra virgin olive oil (the acidity does not exceed 1%). Therefore, from the perspective of cost performance, it is better to choose domestic soybean oil and sunflower seed oil, and pay attention to controlling the amount of oil used at ordinary times.

3. "Pure nature" is misleading.

If the label of a cooked meat product says "pure natural" or "preservative-free (sodium nitrite)", you may feel very relieved.

Dr Joseph Seabra Neck, a professor of meat science at Iowa State University, warned that this may also be misleading. For example, meat products labeled "celery powder, active bacteria culture" can naturally synthesize sodium nitrite, which has certain antiseptic effect and is not recommended to be eaten in large quantities for a long time.

4. Organic food is not necessarily equal to health.

"Organic" does not necessarily mean "healthy". Professor Shashi Bruce, a food safety expert at the University of Illinois at Urbana-Champaign, explained that the use of pesticides, fertilizers, herbicides, etc. is absolutely forbidden in organic food, and there are also high requirements for soil, air and water environment. Moreover, it is difficult to detect whether it meets the organic standards by current scientific means, and we can only rely on the trust of producers and regulatory authorities.

Experts pointed out that in China, on the contrary, the certification and supervision process of "green food" is complete, the regular sampling system is perfect, and the quality is relatively reliable.

5. Use pseudonyms to "reduce" the sugar content.

Walter willett, director of the Department of Nutrition at Harvard School of Public Health, reminded that in many processed foods, enterprises will use pseudonyms such as distilled sugarcane juice, agave nectar, concentrated juice and corn syrup instead of "sugar", which will create the illusion that the products contain no or little sugar. The US Food and Drug Administration (FDA) has now asked manufacturers to list all sugar additives on the ingredient list.
