fava beans, onions, tomatoes
 

Hi everyone. Last week I found some Roasted Fava Beans (also known as broad beans) in the supermarket. I bought a packet & they tasted absolutely great. I've been trying to look up their nutritional value but I'm confused.
Here in carb counter, it says 100g has 19.65g carbs, 5.4g fibre
In fitday, it says 3.5 oz (appx 100g) 50.95g carbs, 14g fibre
In another website, it says a cup (I don't know what's that in grams, sorry) has 31.77g carbs, 9.47g fibre.
Can anyone please give me the correct answer?
Also, when I looked up the carbs of onions & tomatoes, I noticed that their cooked carb-value is quite different from their raw carb-value. For example, 100g of raw onions has 6g-11g carbs, while only 4.01g carbs for 100g of raw onions.
If I'm just gonna fry my onions with a little oil, should I count the "raw onions" carb-value? Please help me, I'm clueless. I thank u for your time. Happy low-carbing!

Welcome to the confusing world of carb counting!

In my Corrine Netzer book it has broad beans listed like this:

raw, 1/2 cup 6.4 carb less 2.3 fiber = 4.1 effective fiber count ( which is what we use...the carbs-the fibre)

Mature beans, boiled, for 1/2 cup are 16.7-4.6= 12.1

Doesn't make much sense does it?

If your beans are roasted, dried and crunchy snacky things, the extra carbs may come from ingredients that are added for flavouring and roasting.

Broad beans don't seem to be much of a carb bargain, even if you are using the low numbers. Corn and carrots fall into that category as well.

Is there a nutrional listing on the packet? One of the things to keep in mind is, if there is no nutrional listing on the packet, can or box, then you want to think twice about buying it. No sense in wasting money on stuff that turns out to be too high in carbs.

I know this doesn't completely answer your question.

The discrepancy may be due to the fact that 100g of the beans will have more water in them when raw or cooked .. But when roasted and dried, they will lose the water weight. 100 grams of dried, roasted beans probably weighed 2 or 3 times as much when in their moist state.

Thus, 100g of dried, roasted beans could have 2 - 3 times the nutrient count as for raw or canned/boiled.
