Just at a quick glance... How can a large egg (50 g) contain 147 g choline? https://www.opennutrition.app/search/eggs-eeG7JQCQipwf Additionally, on https://www.opennutrition.app/search/brown-lentils-VwKWF7CQq... it says: > Unlike larger legumes, they require no pre-soaking and cook in 20-30 minutes, making them ideal for soups, stews, and salads That is not necessarily true.

That is missing a milligram label, thank you for pointing that out. Fix uploading now.

I think they meant mg. Eggs are 293/100gr

when i track nutrition i always get stuck on things like "are the values for a chicken thigh with the bone in or out? do i weigh the meat pre-cooked or after i cook it? do i weigh the bones after i'm done eating and subtract that from the initial weight?" im probably overthinking it.

love the look and i'll keep playing with it but right off the bat i ran into a couple issues:

when i start typing on the search box on the home page it eats the first character (so as i type chicken, what shows up in the next screen's search field is just 'hicken'). and when i search for chicken thigh i don't get any results - seems to just stop filtering? when i press enter in the search field when "chicken thigh" is entered i get a "something went wrong" error.

Also https://world.openfoodfacts.org/ exists, and has an app with everything you'd need. And is just crowd sourcing nutrition labels and barcodes.

That is what I thought.

BTW when you hover over the ingredients, you just get back the name. Are you guys going to do something with it in the future? Right now there is a visual feedback (the cursor changes), but it is not useful yet. I am not entirely sure what I would have expected, perhaps a description of what it is, and upon clicking on it, it could have information gathered from various sources, like examine.com and what have you, but that would be a huge change on its own, the short description upon mouse hover-over should work for now and may not be a huge change.

I have tracked my macro intake seriously for years and use the database every day, as do many folks who used the initial app releases. It's actually more valuable to me to have the data in this format, even estimated, because what happens with other apps is you get gaps in macronutrient reporting on things like Omega 3's, and you wonder 'Am I not eating any Omega 3's or does the database containing the food I ate just not include them?'. In that case I'd much rather have an LLM that had access to as much relevant data as I could feed it reason through approximate nutrient distribution and give me the best estimate it could.

Appreciate the feedback!

Very cool site, great implementation. Calorie burn is dependent on weight and body fat. Individuals who are x+25kg will burn way more calories than x. For users who come to this site to supplement their weight loss information might be misinformed in their journey, or worse,use it as a primary source and become discouraged because their idea of calorie loss is a little skewed due to the conservative numbers currently…

> or worse,use it as a primary source and become discouraged I would hope these people download the free app so they can actually track their food, which has extensive tooling to track weight trends and expenditure changes over time :). But yes, you should be able to customize the assumptions, I just have about 100 more of these things to add and didn't want to wait longer to see feedback.

I don’t know bud, but when I work with diet and nutrition, I feel like I owe users accuracy more than I deserve feedback. Maybe we have a different sense of ethics.
