2021-06-15 Nutrition Trackers

Tuesday, June 15, 2021

Triggered by a member questioning the nutrition tracker differences between SparkPeople, MyFitnessPal, and FarSecret...

Just a thought... (or 2 or 3)
nearly always when I have done a search for a name brand item on SP... I would get multiple entries listed.. and when I looked at the numbers they never matched the numbers on the label I was looking at...
So I would create a new entry with my numbers for my use... (and never check the labels again)
I wondered why the numbers varied so... and chalked it up to sloppy data entry on the part of others...
NOW, I am thinking that the info on the labels keeps changing
SO ,,, maybe I should check the labels to what I have entered to see if this new (box, bag, jar, can) claims the same numbers. and maybe I should add the date to the product name.. so I know when it was created

ALSO, I am wondering how often a product's nutrition data is tested
AND updated on the packaging
AND if there is standardization between testing labs/companies..
AND then there is the normal variation created by the mixing of the ingredients..
as an example, I am pretty sure all tomatoes (by weight) are not created equal depending on variety, soil, fertilizer ripeness, etc

Thus.. at best any nutrition data is an estimate of any one serving because of the innate differences that will naturally occur within each ingredient in the end product.
Also your measurement device may not exactly match the nutrition labels measurement device for serving size.

If you weigh by grams... is it 10 grams just as soon as it says 10 or just before it says 11?
I am thinking about measuring raisins.. I might be able to add 3 more raisins and still register the same weight... so do our scales need to measure to the 1/100th or is 1/10th close enough or ??
and do they really need to be that accurate? just how many calories are we talking about

Maybe we should just record the highest calorie count for the serving and combine that with the lowest numbers for the elements we follow.. such as carb, fat, protein...
with our goal to stay within our calorie range and still consume at least our minimum quantity of carbs, fat, protein.

    cool - to add to your discoveries I found these statements:

    = = = = = = = = = = = = = = = =
    On a food's nutrition label, calories are typically rounded up. When a food contains up to 50 calories per serving, the number of calories is rounded to the nearest five-calorie increment. And when food has more than 50 calories per serving, it may be rounded in 10-calorie increments.

    = = = = = = = = = = = = = = = =
    Declared nutrient values get a 20 percent tolerance for regulatory compliance because it is unlikely that every analyzed batch will have the exact same value
    = = = = = = = = = = = = = = = =

    I don't fret about it too much (which is maybe why I'm in the shape I'm in, lol) but I know it's quite important for some people to be really careful about calories.

    You raised some interesting points - makes me want to learn more. emoticon emoticon

    We have just two months to figure it all out.
    I like the way you think Audra.

    OMG-- this makes me laugh because I was on a rant about it earlier this week when trying to add foods to the MFP tracker-- none of the entries I found were the same as on the label I was looking at-- it's maddening!!

    Well thought out. I like your reasoning for claiming nutritional value.
