This Saturday:

The $41 billion industry built around a nutrient most Americans already get enough of. A bipartisan bill moving through Congress to put a clock on prior authorization. And the doctor who figured out how to save thousands of lives in wartime, then was told his own blood was categorically different.

Sit back, relax, and enjoy the reading.

70% of Americans say they are trying to consume more protein.

That number has held for five consecutive years.

The market did what markets do: they put protein in everything. Protein water. Protein coffee. Protein pasta. Protein chips. A $41.2 billion industry growing toward $69.8 billion by 2033.

The problem: most Americans already get enough protein.

Most Americans are not protein-starved. Adult men average roughly 90–100 grams a day. Women average closer to 65–75 consumes between 100 and 120 grams of protein per day. Even under the updated 2025-2030 Dietary Guidelines, which raised the recommendation significantly, the upper range for active adults tops out around 120 grams. The sedentary adult needs around 50 to 60.

The nutrient we are actually failing at is fiber.

Only 7% of American adults consume the daily recommended amount. Not 7 in 10. Seven in every hundred.

Fiber lowers LDL cholesterol. It slows carbohydrate absorption. It feeds the gut microbiome. Diets high in fiber are associated with lower rates of type 2 diabetes, colorectal cancer, and heart disease.

Nobody got rich telling you to eat beans. Fiber is in vegetables, beans, and whole grains. There is nothing to add, reformulate, or patent.

In October 2025, the CEO of PepsiCo told analysts: "fiber will be the next protein." He said it because his company was launching a fiber-fortified snack. Within a year, articles about fiber had already seen a 9,500% increase in page views.

A July 2026 Harvard study of more than 200,000 people found that the overall quality of a person's diet matters more than whether the food is processed or not. A high-protein ultraprocessed bar is still an ultraprocessed bar.

The people buying protein water are not wrong to want to eat better. But wanting to eat better and knowing how to eat better are two different things. One of them requires a professional. The other requires a purchase.

How much would a nutritionist cost compared to a year of protein supplements?

The market already ran those numbers. It built a $41 billion industry on the answer.

Prior authorization has no federal clock.

Your doctor submits a request. The insurance company has anywhere from 24 hours to several weeks to respond, depending on the payer, the plan, and the specific service.

Last week, we wrote about Ocean McIntyre. She was 34 years old when her doctor requested prior authorization to see a specialist. The insurance company took three months to say yes. By then, the window to preserve her vision had closed. There is no federal law that would have required a faster answer.

There is no federal law requiring a turnaround time for non-urgent cases.

Congress has been working on that.

The Improving Seniors' Timely Access to Care Act, bipartisan, passed through the House Energy and Commerce Subcommittee, would require Medicare Advantage plans to use electronic prior authorization, establish specific response timeframes, and publicly disclose denial rates. Sen. Sheldon Whitehouse reintroduced companion legislation in February 2026 with broader provisions for commercial plans.

The bills are advancing. Floor action is expected.

In the meantime, major health plans voluntarily committed to reducing the volume of services requiring prior authorization by the start of 2026. The American Medical Association called it insufficient. Nine out of ten doctors say prior authorization has delayed medically necessary care.

The fix is currently a voluntary promise and a pending vote.

The wall is still there.

Knowing what is happening in healthcare, even when you are not currently using your insurance, is not optional. It is how you understand what you agreed to before you need it. When the moment comes, the people who moved fastest were the ones who already knew the rules.

In 1940, a doctor named Charles Drew solved one of the most urgent problems in wartime medicine: how to store blood long enough for it to reach soldiers on the front.

His doctoral dissertation at Columbia, "Banked Blood: A Study in Blood Preservation," laid out the technique. Then he put it to work.

Drew directed the Blood for Britain program in 1940, 15,000 American donors, 5,000 vials of dried plasma shipped to hospitals in Britain during the Blitz. He invented the bloodmobile in 1941: self-contained collection centers on trucks that could travel anywhere.

Sixty-three of them ran during World War II. In February 1941, he was appointed director of the first American Red Cross Blood Bank.

He had built the system from scratch.

It was saving lives.

Two months later, the War Department ordered the Red Cross to segregate donated blood by race. Black blood in one batch. White blood in another. The official justification stated the policy was not "biologically convincing" but was "psychologically important in America."

Drew resigned.

In 1944, he wrote a letter calling the order "a grievous mistake, a stupid error" with "no scientific basis for the policy." The Red Cross kept segregating blood until 1948.

The man who understood blood better than anyone alive was told, by the institution that used his research, that his blood was different.

He was right. They kept his system anyway.

Each of them made a decision anyway.

The systems that shape your health were not designed around you. They were designed at scale, for averages, by people who would not be in the room when the consequences arrived.

Knowing that is not pessimism. It is the beginning of asking better questions.

See you next Saturday.
