According to the latest Australian census information.....6.1% of Australians met the daily minimum recommendations for fruit and vegetable intake. Which is 2 pieces of fruit, and at least 5 servings of vegetables.

A serving is 1 cup tightly packed raw, or 1/2 cup cooked.

6.1%.

Those 2&5 recommendations aren't the optimal that I would recommend for healing from chronic disease- they are fundamental for basic health. They provide enough fibre, and colourful plant nutrients to help prevent cancer, and many other chronic diseases.
