The tone varies from analytical to inquisitive, with some posts emphasizing the importance of understanding how food waste contributes to broader ecological and health issues.
Most discussions acknowledge the article's findings on the rise of food waste and its environmental impact, indicating moderate agreement with the published conclusions.
Posts show high interest, referencing detailed data, trends since 1974, and links to original research, demonstrating an engaged audience seeking to deepen understanding.
Several contributions pose nuanced questions, cite related studies, and discuss implications for obesity and resource waste, reflecting moderate to high levels of engagement.
The discussions highlight significant environmental and health consequences, emphasizing water use, calorie oversupply, and resource waste, suggesting the findings are seen as impactful.
Abstract in brief
- Food waste in the US has increased by about 50% since 1974, now averaging over 1400 kcal per person daily, which equals around 150 trillion kcal annually.
- This waste contributes significantly to environmental issues by using up freshwater and fossil fuels, and releasing methane and CO2 emissions from decomposing food, impacting climate change.
- Currently, food waste makes up more than 25% of freshwater use and consumes around 300 million barrels of oil each year in the US.]

Most liked on X and Bluesky15 years ago, we discovered US food waste progressively increased ~50% since the 1970s. Increased weight accounted for only ~1/3 of the increase of calories in the food supply, with ~2/3 being wasted. There's a calorie oversupply & distribution problem! https://t.co/E7Qhq5uSfa https://t.co/jYQEuyFOxH
Previous work showed that increasing levels of food supply was probably enough to explain rising levels of obesity https://t.co/izTGpFlUx3 but an issue with these data is separating increased consumption from increased waste @KevinH_PhD 3/ https://t.co/J9u1gfz7Jv
Increased food waste results from a food system engineered for surplus protein and calories and mostly ultra-processed foods. Of the increased calories available since the 1970s, two-thirds were wasted and one-third accounts for the rise in US obesity: https://t.co/E7Qhq5Mt6I https://t.co/k8o3dzR5wA

@TamarHaspel @AlanLevinovitz @tednaiman @DBelardoMD @marionnestle Sounds like old proposal: “the US obesity epidemic has been the result of a “push effect” of increased food availability and marketing with Americans being unable to match their food intake with the increased supply of cheap, readily available food.” https://t.co/E7Qhq5uSfa

5. 25% of the world’s fresh water supply is used to grow food that is never eaten. https://t.co/dC6JfYKDqn
@Chrest_brett The mathematical model has been validated to give reasonably accurate predictions for overfeeding studies and long-term weight gain. See figure 2 here: https://t.co/E7Qhq5uSfa
