An awful lot.
Thought l would start this l can not always find what l want so a place to add the question. Others may want to add as well then the how many are in the same place. So long as there isnt one of these l have missed.

My question is how many carbs in a Spring Onion please can not find a straight forward answer.

Thanks MID :)
 
Around 10% by weight, so depending on the size, less than one to a couple normally.
 
Not sure how accurate but Google suggested 7g per 100g of spring onions.
 
3g per 100g according to tescos and asda...............................

I think they're listing carbs and sugars separately, possibly, as they have about 3g for each. Maybe 6g in all?
 
If it's an American nutritional panel remember to deduct the fibre from the carbs, they give the total carbs but in the UK it's already deducted to give the net value.
 
When labs measure the amount of carbs in food, they often measure the fat, protein and moisture and what ever is left is assumed to be carbohydrate. Whenever there is a measurement of something, there is an associated error. When you have multiple variables in a measurement, the error in the final value will be the sum of all of the other errors. When carbs are calculated, you have the errors from the fat, protein and moisture measurement, which all add up to give an error on the carb measurements to be around 20%.

Therefore, expect to see a variation of around 20% for carbohydrates for any given food item.

Add this 20% error reading to the 20% variable in most BG monitors and it's no wonder we struggle sometimes !

Plus the 30% variation in injected insulin entering the bloodstream (if you re-use needles). A study I read suggested that there's a 20% variation in the amount of carbs estimated to be in food by a diabetic - i.e. given a plate of food and not nutritional info, estimate the amount of carbs. So yeah, it's a wonder we can do it at all really, isn't it?!
 
I know I recommend it a lot but the book Carbs and Cals is really useful. It shows calories, carbohydrates, protein, fibre, fat and saturated fat. It has a picture of the actual food and shows portion sizes. For example there re photos of 6 different potions of chips, from 10g of carbs to 90g. I thought I was quite clued up on food until I got this book

Yup got carbs and cals first thing l did but not everything is in there :( to be honest not sure why they have so many pictures of one item l know different amounts but still it is a very useful book :)

I tell you l have enough of a problem doing all the carbing l am not adding subtracting or allowing for any % if l decide it is .... then it IS .... And l am putting my hand down on this with a firm foot

The MyFitnessPal app is good as it has a barcode reader function for apps. There is no one app that does it all, I've got 4 I think and that pretty much covers all the bases !

I've got some Salter scales that are quite useful. I weigh what I'm eating on it, type in a code and then it tells me how much protein, carbs, fat, calories and salt there is in it. However these have their limitations, eg most veg is expected to be cooked before you weigh it and things such as cream cheese etc seems to vary a lot compared to what is on the packaging . But I still find them very useful!
