Food as Safety: What Engineers Need to Know About the #1 Workplace Hazard
By Victoria Siegel, Mechanical Engineer, MBA, Certified Community Herbalist & Founder of Rational Body
We spend a lot of time in engineering thinking about risk. We identify hazards. We analyze failure modes. We implement controls. We protect people.
So let me ask you something: when was the last time you ran a risk assessment on your lunch?
I'm serious. Because the number one cause of death, disability, and lost productivity in your workforce isn't a confined space or a rotating shaft or a chemical spill. It's food. And we've been treating it like a trivial matter — a perk, a comfort, a celebration — when it is, in fact, the most persistent safety hazard most of us face every single day.
This is the talk I wish someone had given me fifteen years ago. I'm giving it to you now because I care. And because engineers are uniquely positioned to see through the noise, question the norms, and actually do something about it.
The Top Killers — And What They Have in Common
Let's start with the data, the way we always should.
Heart disease is the #1 cause of death in the United States. The landmark PREDIMED Study found that a Mediterranean diet — rich in olive oil, fish, nuts, and vegetables — reduced cardiovascular events by 30% compared to a low-fat diet. Thirty percent. That's not a supplement. That's food.
Cancer affects 1 in 2 men and 1 in 3 women in their lifetime. PET scans light up tumors with glucose tracers because cancer cells are glucose-dependent. Sugar doesn't just feed cancer — it may actively accelerate it. The research on this is growing and it's not fringe.
Liver failure — which most people associate with alcohol — is now being driven primarily by non-alcoholic fatty liver disease (NAFLD), directly linked to fructose consumption. High-fructose corn syrup, which is in almost everything processed, is metabolized exclusively in the liver. We are flooding that organ.
Alzheimer's disease is now being called "Type 3 Diabetes" by some researchers. Amyloid plaques in the brain — the hallmark of Alzheimer's — are worsened by insulin resistance and inflammation. But here's what's exciting: emerging microbiome research is showing that gut health directly influences brain health. The gut-brain axis is real, it's bidirectional, and it is changeable through diet.
Autism and ADHD — rising at rates we cannot explain through genetics alone. Microbiome research is again pointing us toward the gut. Dr. James Adams at Arizona State University has shown measurable symptom improvement in autism through targeted dietary and probiotic interventions. This is not a fringe claim. This is published research.
The through line? All five of these conditions are food-influenced. Not solely caused by food, but meaningfully worsened — or improved — by what we eat every single day.
Sugar Is Not a Food
I want to make a bold claim, and I want you to sit with it: sugar, in isolation, cannot sustain human life. Therefore, it does not qualify as food.
Compare the definitions. Food: a nutritive material taken into an organism for growth, work, and repair. Drug: a substance with physiological effects when ingested. Sugar hits the same dopamine receptors as cocaine. It causes withdrawal. It creates tolerance. It is engineered to be addictive — and then, when the health crisis it creates becomes undeniable, the same companies go back to their engineers and say, "Make it less addictive." That's the business model.
We have normalized this. We celebrate with it. We hand it to children as rewards. We put it in the middle of conference tables as a gesture of hospitality. And then we wonder why we're exhausted by 2pm, why we have joint pain, why we can't focus.
Speed vs. Velocity: Why Calories Are the Wrong Unit
Here's the engineering reframe I want you to carry with you: counting calories is like counting speed when you need to know velocity.
Speed tells you how fast. Velocity tells you how fast and in what direction. Calories tell you how much energy is theoretically available. They tell you nothing about what your body actually does with it, what signals it sends to your cells, or whether you'll be satiated or starving an hour later.
Think of it this way: every calorie you eat is like a delivery box arriving at your door. Counting calories is counting boxes. But what matters is what's inside. The same delivery truck is going through your bloodstream. Your body looks at what arrives, tries to recognize it, and responds accordingly. When it sees something that looks like food but delivers no usable nutrition — a fake fat, a synthetic dye, a lab-constructed flavor — it gets confused. It releases the wrong signals. And you stay hungry, because your cells are not getting what they actually need.
This is why people eating 2,000 calories of processed food are simultaneously overfed and malnourished.
Your Cells Expect Real Food
Here's something I find profound: your DNA has been shaped over tens of thousands of years by the food your ancestors ate. Your cells have expectations. They know what to do with an heirloom tomato. They know what to do with bone broth. They know what to do with wild-caught salmon and raw honey and fermented vegetables.
They do not know what to do with Red 40.
One of the simplest, most grounding things you can do is look at your family's lineage and ask: what did they eat? Mediterranean? Load up on olive oil, legumes, fish. Northern European? Your body may run beautifully on root vegetables, fermented dairy, and fatty meats. East Asian? Rice, fermented soy, seafood. Traditional diets — before industrialization — were not perfect, but they were coherent. Your cells could recognize the inputs.
When you swap back toward those traditional patterns, a remarkable thing tends to happen: everything gets better. Skin. Energy. Sleep. Weight. Pain levels. Mood. Not because you're on a "diet." Because you stopped confusing your biology.
This Is a Safety Issue
I want to be direct about something: food is the #1 safety risk for most of your workforce, and we don't talk about it that way.
In the field, nutrition deficits affect reaction time, focus, and resilience — the exact capacities that prevent injuries. Working from home, the kitchen is steps away and the temptations are constant, with no social accountability. In the office, the snack cart, the birthday cake, the candy jar on every desk — they're framed as kindness, but their cumulative effect is chronic inflammation and cognitive impairment.
This is not trivial. The top five killers in America are lifestyle-driven. They are happening to your coworkers, your family members, and very likely, to you. And the path from here to there is slow enough that we don't feel it — until we do.
The Path to Change Is Not Linear
I'll tell you what worked for me, and I'll say upfront: it may not be right for everyone.
I went all in. One month. I removed every temptation from my house — every processed food, every condiment with hidden sugar, every snack. I ate meat, vegetables, healthy fats (coconut milk, avocado, olive oil), and smoothies. I learned as I went. I adapted. And at the end of that month, I had broken the addiction cycle, reset my palate, and started feeling — for the first time — what it actually felt like to be well-nourished.
For others, one change at a time is the right path. Swap the breakfast cereal. Then the cooking oil. Then the lunch. Progress is progress.
What matters is that you start looking at it. Because once you see it, you can't unsee it.
What "Normal" Actually Means
Here's something I want you to sit with: common is not the same as normal.
If you have joint pain, headaches, chronic heartburn, skin rashes, acne, brain fog, or mid-afternoon crashes — those are common in 2025. They are not biologically normal. They are your body sending signals that something in the input stream is wrong. We have normalized the signals and suppressed them with ibuprofen and antacids and caffeine. But they don't go away. They compound.
Anorexia and bulimia, when you step back, can look like rational responses to a food system that is genuinely toxic and a cultural narrative that is genuinely confusing. That's not to minimize the tragedy of eating disorders — it's to say that when the food system is broken and we don't know how to feed ourselves, people find their own desperate logic. The answer isn't shame. The answer is clarity.
Food Dyes: A Case Study in Ground-Up Change
California's School Food Safety Act banned six artificial food dyes in 2023. Implementation in schools won't be complete until 2027. That's four years — two to ban, two more to implement. And even then? There's nothing stopping parents from sending dye-filled cupcakes on birthdays.
This is the pace of top-down change. It is slow, it is partial, and it is resisted at every step by industry lobbyists, because jobs are tied to these products. I'm not fighting there. I'm fighting here, at the ground level. Because companies make what we buy. Politicians care about what we ask for. And communities change when people talk.
Here's what you can do right now: read labels. Any dye not derived from a natural source — beet juice, turmeric, spirulina — is synthetic and unnecessary. Red 40, Yellow 5, Blue 1 — these have no place in food. And they certainly have no place in food served to children.
Build the Muscle Memory
This is my favorite part of the talk, and I'll warn you: it's unusual.
I bring candy to my presentations. And then I tell people: see this? Throw it in the trash. Not because I'm asking you to waste it. Because your body is not a trash can — it is worth more than this — and building the muscle memory of seeing these things as non-food, as something you'd no more put in your mouth than you'd put in your gas tank, is one of the most powerful things you can do.
That reaction — "no, that doesn't belong in a human body" — is one you can train. And once you've trained it, a lot of other things get easier.
If you want one book to start with, I recommend Deep Nutrition by Dr. Catherine Shanahan. It will change the way you look at your plate, your family's health history, and your own biological potential.
Community Is the Medicine
Here's what doesn't work: telling people what to do. Shaming. Restricting. Top-down mandates.
Here's what does work: community. People talking to each other. Sharing what they tried. Venting about how hard it is. Celebrating what's working. Asking questions without judgment.
I don't expect to leave this room having changed everyone's mind. Honestly? If one person walks out thinking differently about what's on their plate — one person who mentions it to their partner, or makes one different choice at the grocery store next week — that matters. That ripples.
Because I know what it feels like to be a recovering sugar addict — and yes, I use that word with full awareness — surrounded by my problem being treated as birthday cake and Girl Scout cookies and office snacks. It's everywhere. It's constant. And it's not because people are malicious. It's because we've been taught that this is how we show love.
But here's the truth: real love feeds people real food. Bake a cake with raw honey and almond flour and fruit. Make a snack spread that's beautiful and nourishing. Show up with an heirloom tomato from the farmers market and a hunk of good cheese. That is care. That is celebration. That is food as its best, most ancient self — a gift, not a slow poison dressed in bright packaging.
A Final Note on Empathy
I want to close with something I feel strongly about: this is not a personal failure.
The deck is stacked. The food system is broken. The marketing is sophisticated. The addiction is biological. The cultural programming runs deep. And our doctors — brilliant as they are — received almost no nutrition training in medical school and have seven minutes per patient visit. They cannot fix this.
But we can. Together. One conversation at a time. One meal at a time. One choice at a time.
Look at your plate like an engineer: what are the inputs? What outputs are you getting? What would you change in the system to get different results?
You already have the tools. You just need to point them at the right problem.
The most delicious rebellion of your life is waiting. Start today.
