Receiving charitable food assistance doesn't mean that you're starving, or even that you would be starving without that assistance. What sort of data would you accept to prove that americans are not starving?
Above I've already pointed to TWO types of data that bear on food insecurity in the US, and provided citations:
1. USDA data on food insecurity
2. Food bank usage data
If you wanted to understand the extremes of food insecurity, than data on malnutrition related deaths in the US would also apply:
• Mostafa, N., Sayed, A., Rashad, O. et al. Malnutrition-related mortality trends in older adults in the United States from 1999 to 2020. BMC Med 21, 421 (2023). https://doi.org/10.1186/s12916-023-03143-8
From the paper above -- "Despite some initial decrements in malnutrition mortality among older adults in the U.S., the uptrend from 2013 to 2020 nullified all established progress. The end result is that malnutrition mortality rates represent a historical high...Effective interventions are strongly needed. Such interventions should aim to ensure food security and early detection and remedy of malnutrition among older adults..."
If you wanted to explore malnutrition related deaths for other groups / time periods you could query the CDC Wonder data base using ICD-10 Codes E40 – E46 (as was done in the paper cited above; see also https://www.icd10data.com/ICD10CM/Codes/E00-E89/E40-E46).
I did the query for 2023 and found were >22,000 malnutrition related deaths recorded by the CDC.
If this number went down significantly I would see that as evidence of a decrease in malnutrition in the US. If this number was near zero I would accept your assertion that no/few Americans are starving.
Given the preponderance of data, the notion that one could argue with a straight face that food insecurity in the US is of no concern seems shocking to me.
