Hi Milad,

This would be dependant on what your country (or country where analysis was conducted) classifies as a serving. In the UK, for example, a serving of vegetables is commonly defined as 80g. Therefore if an individual consumed 160g carrots per daily this would equate to 2 servings. Alternatively, you could look at nationally representative nutrition surveys that detail dietary habits of a certain population (average servings sizes etc) and work things out that way.

Hope this information begins to help a little.

Thanks,

Hello,

In the United States, such information should be included in National Health and Nutrition Examination Survey (NHANES).

What's the useful amount?

In my studies, between half and one kg non-starchy vegetables per day prevented slight depressed bood glucose events in overweight patients before the subsequent meal significantly more than no vegetable intake. I consideereed potato as energy dense food, although less dense than cereals.

Hello Milad,

In Portugal potatoes are included in Cereals and tubers food group. One portion of potatoes are 125g.

If you want to read more about it, I would suggest: Rodrigues, S. S. P., Franchini, B., Graça, P., & de Almeida, M. D. V. (2006). A New Food Guide for the Portuguese Population: Development and Technical Considerations. Journal of nutrition education and behavior, 38(3), 189-195. 

Good luck!

Dear Nazarzadeh,

Green has the right answer. Each country (those who use it) has own serving sizes, which are defined by the food and nutrition board or other competent bodies. People's eating behavior, food preferences, national nutrition policy are taken into account to decide the serving size. Its not just a simple figure.

hello,

in exchange list for Meal Planning  ,Foods on the Starchy vegetables list (part of the Starch list and including foods (such as potatoes, com, and peas)1/2 cup(half of cup) of cooked cereal, grain, or starchy vegetable is 1 exchange list and about 90 g potato.

Hi

The serving size depends on the country community and the ethnicity of the Diet. For example Potato is considered as a vegetable in the India especially for the Vegans and the other Vegetarians primarily the major source of Carbs in the Indian society is either Rice or Wheat, so they have a smaller serving size for potatoes. In countries where potato is a staple, and used as the major Carb then they may have bigger servings, most of the international recommendations consider potato as a source of starch. 

If you are doing this for the community you live in then you have see where the potatoes fall into a veggi or a starch and then devise your serving size accordingly
