Prior to the China International Import Expo, we're focusing on a single product that's key to global trade each day. And today, the highlight is on health products. China's health food market is expected to become the world's second largest by 2020. And many Chinese are going for foreign health foods and supplements, thanks to their top-notch quality. CGTN's Tang Bo shows us how eating healthy is becoming easier, and more affordable.

One cup of protein powder a day, an unshakable morning routine for Zhang Lili and her husband. For 16 years, she and her family have made Amway items a big part of their lives. The popular American home product maker is well known in China for its health foods and supplements.

ZHANG LILI HEALTH-CARE FOOD CONSUMER "I always had colds and went to the hospital quite often. But after taking these health supplements, my health picked up and I felt much better. And my confidence is better too."

Zhang knows that the key to a strong body is a healthy diet and proper exercise. But extra nutritional supplements are also important, especially for the elderly.

Currently, China has more than 16,000 health foods and products, among which over 95 percent come from domestic makers while the rest are overseas.

Amway is one of those foreign companies cashing in on the booming market.

VINCENT HWANG, VICE PRESIDENT GREATER CHINA REGION, AMWAY "We have been in China for over 20 years, and have witnessed the growth of the health food market where the per capita disposable income is also climbing. The market is still young. We want to further our development deeper into the third and fourth tier cities."

TANG BO SHANGHAI "An increasing number of Chinese people prefer foreign health-care foods to domestic ones. Experts say a convincing quality, diverse product line, and professional marketing have won over the majority. China has decided to open more to such overseas products. That means a much more competitive market which stands a really good chance of maturing further."

New health food regulations introduced in 2016 have simplified the process of entering the market for both domestic and foreign brands.

Zhu Yi, a health food expert from China Agricultural University says the domestic market will ultimately benefit from the entry of overseas brands.

ZHU YI, ASSOCIATE PROFESSOR CHINA AGRICULTURAL UNIVERSITY "First of all, competition will bring down health food prices. Secondly, foreign brands have reached a high level of product segmentation and are able to meet even picky consumer needs. That has set an example for domestic brands, and will be able to help us find new research hotspots and profit points."

Zhang Lili regularly gives health lectures to her neighbors.

She says she's happy to share her knowledge with those who are becoming more careful and particular about their health foods and supplements.

Zhang says foreign brands with high quality and personalized services will continue to be her choice and what she will recommend to others.
