Skip to 0 minutes and 14 seconds The sixth category is a very popular topic in the past 20 years, functional food. The definition of functional food comes from a theoretical basis and clinical verification. Clinical verification must from many clinical experiments. These experiment results must prove certain food has the advantages to the human body. Only then we will define it as functional food. Functional food usually contains unique nutrition elements. For instance, fish oil is one of the most commonly consumed dietary supplements. Fish oil is an important source to provide omega-3 fatty acids. Fish oil supplements are available as liquids or capsules. Fish oil can also be added or combined in other types of dietary supplements to provide more choices for consumers.
Skip to 1 minute and 18 seconds Clinical experiments shows that omega-3 fatty acids is the main source that benefits health. So if we use omega-3 fatty acids to produce a food product and this product has been through clinical verification to prove its advantages to health. Then we classify this product as a functional food. This advantage to health means to alleviate or prevent a specific disease or symptom. Experiments prove fish oil can lower triglycerides and thus prevent vascular disease. So functional foods, in a way of speaking, has a similar effect of the medicine. This type of product usually emphasizes its effectiveness or function on health. Other than fish oil, there are 2 otehr famous dietary supplements. One is red yeast rice. It is also very well-known.
Skip to 2 minutes and 9 seconds It can be used to reduce cholesterol level. Even our ancestors know the benefits of red yeast rice and created many Asia recipe with red yeast rice such as crispy fried pork, fish, chicken and tofu. These can all marinade with red yeast rice sauce. More than 40 years ago, scientists from Japan and USA found that red yeast rice can be used to restrain endogenous cholesterol synthesis. The experiment group intake more red yeast rice has better control of cholesterol level. The other famous dietary supplement is lactic acid bacteria. Lactic acid bacteria is famous for improving the health of the intestine and stomach. In Chinese proverbs, a healthy stomach and intestine make you younger.
Skip to 3 minutes and 7 seconds More active lactic acid bacteria in the human stomach and intestine will makes the person healthier. Instead of bad bacteria which can harm the human body, if good bacteria such as lactic acid bacteria is in control, the intestines will be healthy and in good condition. So lactic acid bacteria contained products will be labeled as functional food that can help improve the health of the intestines. Overall, there are many functional foods in the markets. More and more scientific evidence proving that there is a lot of good functional food I will give few interesting examples later. The seventh type of food is designer foods. Designer food is related to biotechnology. It is the food specifically used for and designed for a certain disease.
Skip to 4 minutes and 6 seconds Biotechnology includes genetic modification. For example, through genetic modification, a certain species to secrete some substance that is healthy to humans in huge amounts. Designer food means that we use biotechnology or genetic modification to create this type of food. This food exists for specific demands. For instance, goat milk contained with antibiotics; when patients taking antibiotics, it can be taken along with goat milk. The same as coffee. We can see caffeine-free coffee So, removing the unfavorable elements in the food, which is the elements that we do not need through genetic modification or other process methods can create another kind of product. We call it the designer foods. However, the regulation for designer foods is extremely strict before launching to the markets.
Skip to 5 minutes and 14 seconds Whether this type of food will have any impact on the environment remain debates. And there are also morality issues concerned in some cases. In general, we classify health food as 7 categories.
Health Food Category: Functional Food, Designed Food
In this video, Prof. Huang will explain functional food and designed food.
The definition of functional food comes from a theoretical basis and clinical verification. Clinical verification must from many clinical experiments. These experiment results must prove certain food has the advantages to the human body. For example, fish oil is one of the most commonly consumed dietary supplements. Clinical experiments show that omega-3 fatty acids are the main source that benefits health. So fish oil can be categorized as a functional food. This type of product usually emphasizes its effectiveness or function on health.
Finally, designed food is related to biotechnology. It is the food designed for special needs. For example, goat milk contained with antibiotics; when patients taking antibiotics, it can be taken along with goat milk. The same as caffeine-free coffee. In some cases, designed food includes genetic modification.
In general, we classify health food as 7 categories.
