===Impact on nutrition===
The introduction of refrigeration allowed for the hygienic handling and storage of perishables,<ref>{{Cite book |last=Center (U.S.) |first=Food and Nutrition Information and Educational Materials |url=https://books.google.com/books?id=Rr57xpPrTVgC&dq=The+introduction+of+refrigeration+allowed+for+the+hygienic+handling+and+storage+of+perishables&pg=PA14 |title=Audiovisual Guide to the Catalog of the Food and Nutrition Information and Educational Materials Center |date=1975 |publisher=U.S. Department of Agriculture |pages=14 |language=en}}</ref> and as such, promoted output growth, consumption, and the availability of nutrition. The change in our method of food preservation moved us away from salts to a more manageable sodium level. The ability to move and store perishables such as meat and dairy led to a 1.7% increase in dairy consumption and overall protein intake by 1.25% annually in the US after the 1890s.<ref name=":1">{{cite journal|last=Craig|first=L. |author2=Goodwin B. |author3=Grennes T.|title=The Effect of Mechanical Refrigeration on Nutrition in the United States|journal=Social Science History|volume=28|issue=2|pages=325–336| doi=10.1017/S0145553200013183|year=2004|s2cid=144508403 }}</ref>

People were not only consuming these perishables because it became easier for they themselves to store them, but because the innovations in refrigerated transportation and storage led to less spoilage and waste, thereby driving the prices of these products down. Refrigeration accounts for at least 5.1% of the increase in adult stature (in the US) through improved nutrition,<ref>{{Cite web |title=Bibliographies: 'Nutrition – United States – Social aspects' – Grafiati |url=https://www.grafiati.com/en/literature-selections/nutrition-united-states-social-aspects/ |access-date=2024-03-12 |website=www.grafiati.com |language=en}}</ref><ref>{{Cite journal |last1=Craig |first1=Lee A. |last2=Goodwin |first2=Barry |last3=Grennes |first3=Thomas |date=2004 |title=The Effect of Mechanical Refrigeration on Nutrition in the United States |url=https://www.jstor.org/stable/40267845 |journal=Social Science History |volume=28 |issue=2 |pages=325–336 |doi=10.1017/S0145553200013183 |jstor=40267845 |issn=0145-5532}}</ref> and when the indirect effects associated with improvements in the quality of nutrients and the reduction in illness is additionally factored in, the overall impact becomes considerably larger.<ref name=":1" /> Recent studies have also shown a negative relationship between the number of refrigerators in a household and the rate of gastric cancer mortality.<ref>{{cite journal|last=Park|first=B. |author2=Shin A. |author3=Yoo, K.|title=Ecological Study for Refrigerator Use, Salt, Vegetable, and Fruit Intakes, and Gastric Cancer|journal=Cancer Causes & Control|volume=22|issue=11|pages=1497–1502|doi=10.1007/s10552-011-9823-7|pmid=21805052 |display-authors=etal|year=2011|s2cid=24595562 }}</ref>
