How many carbs in broad beans

According to the McCance and Widdowson nutritional values tables fresh raw broad beans have 7.2g of carbs per 100g

 

The carbs per 100g values on the internet and on packaging are estimates.
For example, a slice of cake may have more currants in than the next, a strawberry maybe riper than the next, a broad bean may have more skin than the next, ... So, I am not surprised the internet gives different values.
I recollect reading somewhere that carb values are measured by setting fire to a sample of the food item and weighing the remaining carbon (ash).
We quote carb values as if they are fact. Some people limit their carbs to a certain amount based on these estimates and worry if they are 0.5g carbs over, and some people precisely calculate their insulin according to these estimates.
Given how many other things can affect my blood sugars (stress, time of month, exercise, time of day, ...), I do not stress that the values on the internet differ, I take one (usually one in the middle ground) and use this for my insulin dose calculations, test and tweak if necessary.

 

I did Keto for 2 years, it was my to go to , needed to bring BS down...It's great but hard work...also ihave given up meat...still in ketotis and feeling fine...finding my way around proteine the vegan meat way...x

 

As a guesstimate I would say around 6g carb per 100g

 

You can buy dried broad bean snacks in many places.. other half likes them. As they are dried they will be far higher in carbs per gram than fresh.

 

It's also worth being aware that the UK and the USA calculate carb values slightly differently - UK treats carbs and fibre separately, but in the USA fibre is included with (other) carbs and can be subtracted from total carbs giving "net carbs". So UK total carbs = USA net carbs, which is why if you check on the web you will see different values and so need to be aware of which version you are looking at.

ETA I like broad beans, but as a T2 I really only need to consider what my meter tells me that my post broad bean meal glucose levels are...
