Many resources are available for figuring out what constitutes a serving of vegetables or fruit. Among those is a Canada’s Food Guide list of servings.
The examples for vegetables and fruit, from the above-noted website, includes, by way of example:
125 mL, ½ cup, 6 spears
125 mL, ½ cup
Bok choy/Chinese cabbage (Choi sum)
125 mL, ½ cup cooked
125 mL, ½ cup
125 mL, ½ cup, 4 sprouts
125 mL, ½ cup, 1 large
125 mL, ½ cup
[The list goes on]
Once I figured out how the serving sizes work, I found that ensuring that I had 7-plus (more precisely, about 10) servings a day of vegetable and fruits, with a predominance of vegetables, was an easy task. It’s not as complicated as I would have imagined, before I made a point of keeping track of things.
Fruit and vegetable consumption and all-cause, cancer, and cardiovascular disease mortality
A relevant resource, that I’ve found of much interest, is an article entitled “Fruit and vegetable consumption and all-cause, cancer and CVD mortality: analysis of Health Survey for England data. (2014).”
You can read an Open Access version of the article at the following link:
Consumption of vegetables appeared to be significantly better than similar quantities of fruit.
Raw vegetables have been shown by others to have a stronger inverse association with mortality than cooked vegetables
Fruit consumption was not significantly associated with deaths from cancer or from CVD [cardiovascular disease]. Vegetable consumption was significantly associated with reduced CVD and cancer death.
Fruit and vegetable consumption is inversely related to household income.
We found a strong inverse relationship between fruit and vegetable consumption and all-cause mortality which was stronger when deaths within a year of baseline were excluded and when fully adjusting for physical activity. Fruit and vegetable consumption was significantly associated with reductions in cancer and CVD mortality, with increasing benefits being seen with up to more than seven portions of fruit and vegetables daily for the latter. Consumption of vegetables appeared to be significantly better than similar quantities of fruit. When different types of fruit and vegetable were examined separately, increased consumption of portions of vegetables, salad, fresh and dried fruit showed significant associations with lower mortality. However, frozen/canned fruit consumption was apparently associated with a higher risk of mortality.

A useful reference regarding fine points such as whether or not potatoes can be viewed as vegetables is entitled: Fruit and vegetable consumption in Europe – do Europeans get enough?
You can find many such resources – including more recent ones than the 2012 resource noted in the previous paragraph – by doing a Google search for “surveys of vegetable consumption.”
In previous posts, I’ve written about vegetables and related topics; you can find them by doing doing a search for “vegetables” using the search engine at this website. Below are some of the posts:
