    2. soy milk, water, fruit juice, low fat / skim milk

  3. Lunch recommendation:

    1. Make carbohydrate the focus of your meal: Eat more rice, pasta, noodles, do not just have a big piece of steak or chicken with French fries.

    2. Eat vegetables whenever possible: Order green leafy vegetables in Chinese type eatery and have some mixed vegetables in Western type eatery.

    3. Order foods which are lower in fat. E.g. choose meats with less fat (pork chop, roast beef, sliced beef, steamed chicken are usually lower in fat); choose tomato based sauce or soup; choose foods which are not fried; choose fruits as dessert.

  4. Dinner recommendation:

    1. If not enough fruits and vegetables have not been eaten during the day, try to make up at dinner.

    2. Make carbohydrate you focus.

  6. Choice of beverage:
