Diet, Nutrition and the Context of Risk (Part 2): Food Poisoning
G. Douglas Andersen, DC, DACBSP, CCN
Other than the morbidity and mortality linked to eating too much food, "all-natural" organisms that contaminate our food cause more illness, more hospitalizations and more death than food contaminated by heavy metals, plastics, preservatives, artificial colors, emulsifiers, artificial sweeteners and pesticides combined. In fact, the numbers are staggering (see Table 1) and yet for some reason, food poisoning does not seem to resonate compared to more innocuous or esoteric threats.
For example, when I lecture on the topic, the possibility that GMO crops might cause widespread illness someday (they haven't yet) generates much more passion than the widespread illness caused every year by contaminated food. After reading quite a bit about it, I believe part of the problem is many people don't recognize food poisoning when they have it, since the CDC estimates one of every six Americans contracts it every year. In other words, people know they're sick when symptoms such as an upset stomach, abdominal cramps, nausea, diarrhea and vomiting are present. The problem is they call it the stomach flu or the 24-hour flu – two ailments that technically don't exist (see below) – when in fact, they probably have food poisoning.
tricky to diagnose:6
Most of the time, the last thing you ate isn't what made you sick.
Many foodborne diseases don't produce the toxins until after they are in your intestines, and once the process begins, it can take days to weeks for levels to increase enough to cause problems.
The same pathogen can affect different people differently.
Sometimes only one person gets sick after eating a shared meal that was contaminated.
A person's current immune status and stress level play a role in who can stop a bug and who cannot.
Good fortune can dictate who misses a pocket of high infestation when sharing a common source such as an appetizer.

Building on a historic March 2026 meeting between Make America Healthy Again and chiropractic leadership, MAHA has announced the launch of the MAHA Chiropractic Hub, “a coordinated national partnership uniting MAHA Center, MAHA Action, and the chiropractic profession, including national associations, state organizations, practitioners, educators, researchers, and patient advocates. The Chiropractic Hub will advance federal policy, expand patient access, and build broad public support for chiropractic care across America.”
The chiropractic profession is confronting one of the most significant federal regulatory threats it has faced in decades. A new U.S. Department of Education (ED) accountability framework – commonly referred to as the “Do No Harm” (DNH) regulation – could place many chiropractic programs at risk of losing access to federal financial aid (student loans), potentially reshaping the future of chiropractic education and workforce development across the United States.
Pain has become the dominant language of musculoskeletal healthcare. Numeric pain-rating scales and symptom reports are routinely used as primary indicators of clinical success. But while pain reduction is meaningful, it is an incomplete and often misleading representation of recovery. This has real consequences for patient adherence, long-term outcomes, and how conservative care is perceived within the broader healthcare system.
