Revision #1435

''Part of the [[using-the-ios-app|Loopa iOS app]] guide.''

'''Health Info & Sources''' lists where Loopa's numbers come from: the equations behind your calorie and protein targets, the guidance behind your macros, and the food and supplement databases. It is part of '''Loopa Basic''' and '''Loopa Premium'''.

== Where to find it ==

* '''Health''' tab › '''My Loopa''' › '''Health Info & Sources'''. You can also search the Health tab for it.
* '''You''' tab › '''About''' › '''Health Info & Sources'''.
* Any '''Sources''' button (an ⓘ, read by VoiceOver as "Sources and medical disclaimer"). It sits beside your targets on [[today-s-page|Today's Page]], in Health Settings and on the plan you see at the end of setup, on the [[the-full-dossier-report|Weekly report]] (the summary, Energy Balance and Macros cards), in the [[the-what-if-simulator|What-If simulator]], and at the foot of [[help-me|Loopa AI Coach]]. A Sources button opens the same list as a sheet titled '''Sources'''; tap '''Done''' to close it.

== Not Medical Advice ==

The list opens under '''Not Medical Advice''': "Your targets (calories, BMR/TDEE, protein, carbs and fat) are estimates from published equations and public-health guidance. They're a starting point, not a prescription, and they're general wellness information, not medical advice. Talk to your doctor or a registered dietitian before making changes, especially if you have a medical condition, are pregnant or nursing, or take medication."

'''INR target range'''

'''Food & nutrition database'''
* '''USDA FoodData Central''': Foundation, SR Legacy, Branded and FNDDS data, including restaurant and fast-food items. Public domain.
* '''Open Food Facts''': food and barcode data, including the ingredient lists Loopa reads when you scan a packet. Used under the Open Database License.
* '''Powered by fatsecret Platform API''': branded, restaurant and menu items, which is where most chain-restaurant and supermarket products in Loopa come from. Used under licence.
* '''Loopa’s own catalogue''': a hand-kept set of corrections and additions, plus every food you save yourself. Loopa's corrections outrank the source database, so a fix stays fixed after the next update.

'''Supplement labels'''
* '''NIH Dietary Supplement Label Database (DSLD)''': supplement products and their Supplement Facts panels, shown as printed on the label. Public domain.
