Feijoas- why a B- grade?

I live in New Zealand. I love this time of year cos the feijoas come into season. I bought some today and had a couple after dinner. I came to CC to log them in and was shocked to see they're graded a B-. Unlike most other fruits they have no sugar in them. (***This is according to CC*** And apparently according to them they have no fibre in them either.***) They are low in sodium & fat. In my mind they are healthy; really healthy. They also are great for helping you to go toilet (In fact better than most other fruits.) Why such a bad grade?

Added the bit in brackets (***) as my information came from CC.

Ignore the grades. They tend to be a law unto themselves.  Feijoas are definitely healthy to eat! If you want to you can click 'report bad grade' or something to that effect on the page and it will get re-evaluated by an actual person.

I miss Feijoas! I'm a kiwi, but in the UK.  We dont get them here :(

I miss Feijoas too! I am also a kiwi, living in Malaysia. No Feijoas here but, I guess, lots of cheap tropical fruit to substitute with. I still wish we had Feijoas though! They rock Hey... I wonder how many kiwis are on CC?

Feijoas - B+

That's the generic listing at the bottom of the list, but there are some brand name listings under this item with lower grades.  It's most likely due to missing information on the nutrition label. 

If you think the grade is wrong, scroll down to where you see report bad grade, and click there to let managment know it might be wrong. 

Feijoa's are great. That's a pity that you can't get them in the UK & Malaysia. I know they export them to the US, as the first job I ever had when I emigrated to NZ (from Scotland) 16 years ago, was picking & packing feijoa's for export.

I definitely think the grade is wrong, unless there's something bad in them that I'm not aware of. I'll do some browsing around some NZ sites for nutrition information and then if I still think it necessary, I'll report it as a bad grade.

Thanks for the replies.

I did some research and it would seem that in the CC analysis of feijoas, they haven't gotten all the nutrition details. Per 100grams, they actually have 10grams of sugar, so I guess this could possibly account for a lower grade. Here's the details I found:

(per 100g of freshly picked fruit)
Vitamin C 30mg
Energy 190kJ (45 calories)
Dietary fibre 4g
Sugars 10g
Protein 0.5 to 1gm
Fat 0.3g

You can manually enter the fruit using the info. you found and see if it gives a better grade. It does appear that CC's current entries are ignoring some good points, like the fiber!

I looked up the last one on CC rated a B+.  It listed no sugar content for the fruit and no fibre.  If that is the case and not misinformation, that's probably the reason it's not an A.  It would be all starch, no fibre, much like white rice.

I did manually enter it and it came out a B+.

If you compare feijoa to grapes. Grapes have far more sugar, way less fibre & have more calories, but they get an A grade. I think I might just ignore the CC grades and just focus more on the calorie counting.

I found some in-depth analysis of feijoa and when I log 100grams in my food log using the figures provided here: http://www.ernaehrung.de/lebensmittel/en/F563 011/Feijoa.php I finally get the grade-A that I would expect it to get.

Hey, no wonder a B... should be a C if you see it the other way, if 100 grams of it have 10 grams of sugar, this amounts to 40 calories out of 45, meaning, 88% of its caloric value is sugar.

Or imagine diluting 40 grams of sugar in a 100cc glass of water...

???? You lost me with your maths. How come 10 grams of sugar suddenly became 40 grams?

10 grams per 100 grams is 1/10th, so therefore only 4.4 calories is from sugar. Bananas, grapes and other fruits have similar amounts of sugar per 100 grams, if not more, and they're all graded A.

Sorry, it should be 10 grams, 40 cals.

10 grams per 100 grams is 1/10th, so therefore only 4.4 calories is from sugar.

Sorry, now its your reasoning that's wrong.

1 gram or carbs, sugars and protein has 4 calories
1 gram of fat has 9 calories

Of course 10 grams is 1/10 of 100 grams.
However, 10 grams of sugar are 40 calories out of a total of 45 calories in one fruit - 88% of its caloric value.

On my water example, 10 grams of sugar in 100cc of water - or a litre, it does not matter - is 40 calories out of 40 calories, so 100% calories from sugar in that cup, as water has no calories.

Well ya learn something new every day. I had no idea that 1 gram of fat, sugar or protein had X amount of calories in it.

True. There are likely better sources of information but this one makes for an easy read  and is quite clear:

http://www.bodybuildingsecretslive.com/nutrit ion-faq/if-i-eat-1400-calories-a-day-how-many -of-those-calories-should-be-protein-carbs-fa t-fiber/

They explain how to spread the calories through macronutrients (how much from fat, carbs and protein) and has some information on fibre.

I book I can recommend (it totally changed my diet) is "burn the fat, feed the muscle", by Tom Venuto. It is also a good and easy read will lots of useful information presented in layman's terms.

A calorie is basically a unit of energy - the amount of energy required to raise the temperature of one gram of water by 1 °C.

From "Howstuffworks":

A calorie is a unit of energy. We tend to associate calories with food, but they apply to anything containing energy. For example, a gallon (about 4 liters) of gasoline contains about 31,000,000 calories.

Specifically, a calorie is the amount of energy, or heat, it takes to raise the temperature of 1 gram of water 1 degree Celsius (1.8 degrees Fahrenheit). One calorie is equal to 4.184 joules, a common unit of energy used in the physical sciences.

Most of us think of calories in relation to food, as in "This can of soda has 200 calories." It turns out that the calories on a food package are actually kilocalories (1,000 calories = 1 kilocalorie). The word is sometimes capitalized to show the difference, but usually not. A food calorie contains 4,184 joules. A can of soda containing 200 food calories contains 200,000 regular calories, or 200 kilocalories. A gallon of gasoline contains 31,000 kilocalories.

The same applies to exercise -- when a fitness chart says you burn about 100 calories for every mile you jog, it means 100 kilocalories.
