The 'Normal' Problem

Introduction

The modern food system solved starvation. We're not dying of scurvy or rickets anymore. Grocery stores are full, and we fortify everything from bread to orange juice. But somewhere in that societal advancement, we stopped asking a different question: what's the difference between enough nutrients to survive and those needed to thrive?

The research on that gap is sobering.

How many lab reports do you think I've looked at in a fifty year medical career? From an emergency medicine perspective I was only looking at numbers that told me something needed to be done immediately or it could be dealt with later. Far and away most were "normal." I spent years looking at my own bloodwork and seeing "normal" results. Yet I'd wake up tired, hit that afternoon wall around 2 or 3 PM, and need willpower just to push through basic tasks. I told myself it was age.

Looking back, I wasn't accepting age. I was accepting a deficiency state that had become so common it was statistically normal.

The data tells a story that most of us aren't hearing. Analysis of national health surveys shows that 31% of Americans are at risk for at least one vitamin deficiency based on blood markers. When researchers look at dietary intake rather than blood levels, the numbers get worse. Over 90% of us fail to eat enough of essential nutrients like Vitamin D and Vitamin E. We're not starving. But our cells are running on half power and it's considered normal because everyone else is in the same boat.

What changed my thinking was discovering why some nutrients matter more than others. There is a gap between "preventing disease" and "supporting optimal function" that may be the most important health distinction that very few talk about.

The Engine and the Thermostat

Let's break down what's actually happening at the cellular level and why it matters for how you feel.

Think of your body as a house with two critical systems working together. Your mitochondria are like the furnace in the basement. They take the fuel you give them and turn it into the heat that keeps everything running. Your thyroid gland is the thermostat on the wall, telling the furnace how hard to run based on what your body needs.

These two systems speak to each other constantly through a chemical "wiring" language, and that wiring is made of specific micronutrients. When you're short on those nutrients, the conversation breaks down. The thermostat can't send a clear signal, so it lowers its output. The furnace can't burn fuel efficiently, so it produces less heat. You end up cold, tired, and foggy. Nothing looks "broken" on standard lab tests.

Because we've built our definition of health on the absence of disease, the basic biochemistry of optimal function often gets overlooked.

The Triage Decision Your Body Makes Without Asking

In 2006, a researcher named Bruce Ames proposed something called the Triage Theory that explains what happens when nutrients run low. His insight was simple but profound: when micronutrients become scarce (not absent, just insufficient), your body makes choices about how to use what's available.

It prioritizes short-term survival over long-term health. The heart keeps pumping. Basic metabolism continues. But the maintenance work gets delayed. DNA repair slows down. Antioxidant defenses weaken. Mitochondrial function declines just enough that you can survive, but not enough that you thrive.

You're in triage mode, and you don't even know it.

The scary part is that triage looks normal on bloodwork. You're not deficient enough to trigger disease markers. You're just deficient enough to feel like garbage while your doctor tells you everything's fine.

I've been there. I spent years in that zone, assuming fatigue was inevitable at my age. It wasn't inevitable. It was reversible.

The Raw Materials Your Cellular Machinery Actually Needs

Most nutrition advice focuses on macronutrients: how much protein, fat, and carbohydrate you eat. That matters. But your cellular engines don't run on macros. They run on specific micronutrients that act as cofactors in the chemical reactions that produce energy and regulate metabolism.

When researchers looked at what nutrients are most commonly insufficient in the American diet, a pattern emerged. We're not missing everything. We're missing a specific subset of nutrients that happen to be critical for mitochondrial and thyroid function.

The Spark Plugs: CoQ10, Copper, and Heme Iron

Inside your mitochondria, energy production happens through something called the electron transport chain. Think of it like a bucket brigade passing electrons down a line. Each handoff requires a specific molecule to catch and pass the electron to the next station.

CoQ10 is one of those electron carriers. So is copper. So is heme iron (the form of iron found in animal tissue, not the non-heme iron in plants or supplements).

Without these molecules in sufficient amounts, the electron transport chain backs up. Electrons leak out where they shouldn't, creating oxidative stress. Energy production drops. You feel tired not because you're lazy or old, but because your cells literally cannot make ATP efficiently.

Here's where food choices matter more than most people realize. When researchers measure the nutrient density of different foods, organ meats (particularly heart and liver) contain 10 to 100 times more of these specific cofactors compared to muscle meat. A serving of beef liver has more bioavailable CoQ10 than you'd get from 20 steaks. It's not even close.

I'm not suggesting organ meats taste good or that you need to eat them. I'm suggesting the biochemistry explains why populations that consumed whole animals (nose to tail) didn't have the "normal" fatigue epidemic we see today.

The Fuel: Tyrosine, Iodine, and Selenium

Thyroid hormone is built from two ingredients: the amino acid tyrosine and the mineral iodine. The active form of thyroid hormone (T3) is made by removing one iodine atom from the storage form (T4), and that conversion requires enzymes made from selenium.

This is where modern food systems have quietly created a problem. For most of the 20th century, iodized salt was the primary source of iodine in the American diet. It worked. Goiter and severe iodine deficiency essentially disappeared.

Then two things happened. Public health campaigns told us to reduce sodium intake. People switched from iodized table salt to sea salt or pink Himalayan salt, which typically contains no iodine. Iodine intake dropped, but not enough to cause the acute thyroid disease that would show up on screening. Just enough to put people into that triage zone where thyroid function is sluggish but technically normal.

At the same time, our environment filled with chemicals that look like iodine to your body. Fluoride in water. Bromine in flame retardants and food additives. These are called halides, and they can compete with iodine for absorption in the thyroid gland. If your iodine intake is marginal and you're exposed to fluoride and bromine regularly, your thyroid may uptake these imposters instead of the iodine it actually needs.

The result is exactly what you'd expect from triage: your body conserves iodine for the most critical functions and lets everything else run slower. You're cold. You're tired. Your hair thins. Your doctor checks your TSH and says you're fine.

What I'm Actually Doing Now

Once I understood how much of metabolism depends on nutrient availability, I realized my habits needed to shift in a few practical ways.

Rethinking Protein Sources

I used to think protein was protein. Get enough grams per day and you're covered. But the amino acid profile matters for thyroid function (you need tyrosine), and the cofactor density matters for mitochondrial function. I'm eating more seafood now, particularly salmon and shellfish, because they're dense in both selenium and iodine. Twice a week minimum.

Desiccated Organ Supplements

I'll be honest: I don't love the taste of liver. But I respect the nutrient density data. I'm taking freeze-dried organ capsules (heart and liver) at least three to five times a week. Each serving provides the CoQ10, heme iron, and copper that I wasn't getting from muscle meat alone. My energy hasn't dramatically transformed overnight, but the trend is upward. I'm tracking it.

Switching Back to Iodized Salt

This was humbling. I spent years using sea salt thinking it was healthier. It probably has trace minerals that table salt lacks, but it doesn't have iodine unless specifically fortified. I switched back to iodized sea salt and I'm measuring my intake to make sure I'm getting roughly half a teaspoon daily. That's about 150 micrograms of iodine, which is the amount research suggests supports thyroid function without overdoing it.

Brazil Nuts for Selenium

Two to three Brazil nuts daily provides all the selenium I need for thyroid hormone conversion. It's cheaper than supplements and the absorption is better because it comes packaged with other nutrients that support selenium utilization.

Filtering Drinking Water

I love the taste of GOOD water. Most of the water I drink comes from a well drilled 300 feet into granite. For 30 plus years I've appreciated that most toxins we put in our bodies come from the water we drink. I've purchased at least 10 Reverse Osmosis (RO) water systems over the last 10 years alone. I put them everywhere I will be drinking water. They're a few hundred dollars up front but then very cheap to maintain. Do a cost analysis on that vs buying water (usually in plastic). We have one by the back door and my grandkids are frequently there filling up their water bottles when they're playing outside. On this topic alone they eliminate fluoride and chlorine which can attach and block iodine. The research on fluoride's impact on thyroid function is strongest in populations with low iodine intake. I figure if I'm going to support my thyroid, I might as well reduce the competition for iodine uptake.

Water quality is a huge topic. We'll dig in more later. First, it should be clean. Buy an RO filter. Don't drink or cook from plastic. Water has structure. That's a deep dive as well. I can taste the difference. My water is structured from flowing through crevices in granite deep below my house. When I am away and return home I am so thankful for the water I have been drinking 35 years.

Adding a Multivitamin

A high-quality multivitamin covers the gaps for nutrients I might not get consistently from food, particularly Vitamin D (which 93% of us are short on according to dietary intake surveys) and magnesium. In addition to a multivitamin I add more Vitamin D which I need based on my blood tests.

The goal isn't perfection. It's getting my cellular machinery out of triage mode and into maintenance mode.

The Bottom Line

Do you have "normal" lab or optimal lab values?

"Normal" just means the area under the curve where 90% of the population lives. When you look around do you think 90% of the people you see have the health that you want?

You can change this. It takes time because you're rebuilding nutrient stores that may have been depleted for years. But the direction matters more than the speed.

I'm 75 years old and still learning. Still tracking my results. Still adjusting based on what the research suggests and what my body tells me. That's what this journey looks like: not perfection, but steady progress based on understanding what your cells actually need.

Your body is doing the best it can with what you give it. Maybe it's time to give it more.
