The short answer

You stand at the stove and wonder if you eat enough protein. And if you cook for your mom or dad, you wonder about them too.

The US minimum, called the RDA, is 0.8 grams of protein per kilogram. At 150 pounds, that is about 54 grams a day. The new US Dietary Guidelines, from January 2026, aim for 1.2 to 1.6 grams per kilogram. That is about 82 to 109 grams. A group of experts on aging looked at people over 65. They say at least 1.0 to 1.2 grams per kilogram. That is about 68 to 82 grams.

So the minimum is low, and the newer advice is higher. And the beef on your plate? Just four companies buy most of the young cattle it comes from.

How much protein do you need after 50?

Quick answer: the US minimum is about 0.36 grams per pound you weigh. The 2026 US guidelines aim higher, at about 0.54 to 0.73 grams per pound.

You stood at the meat case longer than you meant to. A pack of ground beef in your hand. Is it enough protein for you? For your dad?

What does 0.8 grams per kilogram mean?

A kilogram is about 2.2 pounds. So the RDA works out to about 0.36 grams for each pound you weigh. At 150 pounds, that is about 54 grams a day.

Harvard Health calls it "the minimum amount you need to keep from getting sick." It is a floor, not a goal.

And the minimum does not go up with age. A 2017 review from McMaster University says the RDA has no separate number for older adults.

In January 2026, the USDA and HHS put out new Dietary Guidelines for Americans. They set a protein goal of 1.2 to 1.6 grams per kilogram a day. At 150 pounds, that is about 82 to 109 grams.

The same guidelines say some older adults need fewer calories but the same or more protein. At 65, one group of experts on aging gives its own number.

What changes after 65?

Quick answer: a group of experts on aging says people over 65 need more than younger adults. At 150 pounds, that is at least 68 to 82 grams a day.

In 2013, a group of experts on aging called PROT-AGE went through the research on protein and age.

They wrote that "older adults need more dietary protein than do younger adults." For people over 65, they advise at least 1.0 to 1.2 grams per kilogram a day.

What does 1.0 to 1.2 mean at 150 pounds?

Say your mom weighs 150 pounds. That is about 68 kilograms.

At 1.0 gram per kilogram, she lands at about 68 grams a day. At 1.2, it is about 82 grams.

That is about 14 to 28 grams more than the RDA, and at or under the new US goal.

Who should not eat more protein?

PROT-AGE names one clear exception. People with severe kidney disease who are not on dialysis may need to limit protein.

If that is your dad, the higher number is not for him. His number comes from the doctor who treats his kidneys.

For everyone else at your table, the next question is where that protein comes from.

Where does most store beef come from?

Quick answer: four companies buy 85 of every 100 young cattle raised for beef.

You want good beef for your dad. Nothing wrong with wanting that.

The trouble starts long before the beef gets to the store.

In January 2024, the USDA's own research service called meatpacking "a concentrated industry." It said the four largest firms handle 85 percent of all steer and heifer purchases.

Steers and heifers are the young cattle raised for your steaks and roasts. In 1980, the top four bought 36 percent of them.

So a rancher has few places to sell. In most of the country, USDA says, it is two to four buyers.

News reports call them the Big Four: Tyson, Cargill, JBS and National Beef.

What goes into store ground beef is a whole other post. This one is about who stands between the ranch and your fork.

What happened	The concern	Named authority and date	What it does NOT mean
US minimum (RDA), 0.8 g per kg	About 54 grams a day at 150 pounds	Harvard Health, 2023	It is a floor, not a goal
New US protein goal, 1.2 to 1.6 g per kg	About 82 to 109 grams a day at 150 pounds	USDA and HHS Dietary Guidelines, January 2026	Not a prescription for one person
Over 65 advice, 1.0 to 1.2 g per kg	About 68 to 82 grams a day at 150 pounds	PROT-AGE study group, 2013	Not for severe kidney disease without dialysis
Four firms buy 85 percent of steers and heifers	Few hands between ranch and store	USDA research service, January 2024	Not proof the meat is unsafe
Tyson and Cargill agreed to pay $87.5 million to shoppers	Claims they held back supply to raise prices	Federal court in Minnesota, May 2026	Both denied wrongdoing
JBS agreed to pay $83.5 million to ranchers and other plaintiffs	Claims it worked with rivals to curb beef supply	Filed in federal court in Minnesota, January 31, 2025	JBS denied wrongdoing

Not one row tells you who raised the animal on your plate.

The case against my own story

Quick answer: three fair points, and I will not pretend they are wrong.

One. This is not new. USDA says the top four already bought 81 percent of steers and heifers by 1995.

Two. A settlement is not a guilty verdict. The companies denied the claims they paid to settle.

Three. Store beef still has protein. Three ounces gives your dad about the same grams either way.

So why does it still sit wrong with me?

Because four companies buy most of the cattle. And there is no one to call and ask how your dad's dinner was raised.

What do I do instead?

Quick answer: find a ranch you can talk to, and get to know the rancher.

Find a farm or ranch near you. Go meet the rancher. Ask how the cattle are raised and where they are processed. Then listen to how the answer sounds.

If there is no ranch near you, there is the ranch I work with, Riverbend Ranch.

The pack in the meat case rarely tells you who raised the animal. A rancher can.

What do the grams look like on a plate?

USDA lists 3 ounces of cooked 90 percent lean ground beef at about 22 grams of protein. One large egg has about 6.

For a 150 pound mom, the PROT-AGE number starts at about 68 grams. One 3 ounce serving of beef covers about a third of that.

Do the small thing first. Tonight, write your mom's weight on a sticky note and do the math once.

Shannon's Advice

Straight talk from Shannon

I do not call them grocery stores. They are poison centers meant to do you and your family harm. It is not just the brands who are doing the harm, it is the stores themselves. They allow these toxic products on their shelves. People are sick and dying. This is a very serious matter. How can we ever trust them again?

We can't trust them. That is where Switch to America comes in. We are a new supply chain, built on family values, trust and affordability.

You do not have to take my word for it. The proof is in my blog posts, the recalls, the lawsuits and the fines, and in the app I built called The Family Home Toxic Scorecard. Also, inside my Switch Circle private community, we talk about real solutions.

Women come to me exhausted, in pain, stressed out, and on a list of prescriptions they never wanted. I have spent over 20 years helping women get off prescription medications. I help families reclaim their health.

We cannot stop them. I have stopped expecting to. However, we can stop walking into their stores. We are linking arms and together taking our control back. Control of our health and our finances.

The receipts

USDA Economic Research Service, January 2024. The four largest firms handle 85 percent of all steer and heifer purchases.
Tyson and Cargill consumer settlement, October 2025. Tyson agreed to pay $55 million and Cargill $32.5 million to shoppers who accused them of holding back supply to raise beef prices. A federal judge in Minnesota gave final approval on May 27, 2026. The companies denied any wrongdoing.
JBS settlement with ranchers and other plaintiffs, filed January 31, 2025. JBS agreed to pay $83.5 million to settle claims that it worked with other packers to curb beef supply and lift prices. JBS denied wrongdoing.
NBC News, November 7, 2025. Attorney General Pam Bondi said a Justice Department investigation of the biggest meatpackers was "underway." In May 2026, the department announced antitrust investigations into meatpacking. The industry has denied claims of collusion, and an investigation is not a finding of guilt.

What else do people ask?

Is the higher number for me or for my mom? PROT-AGE wrote its number for people over 65, so that one is for your mom. The 2026 US guidelines aim for 1.2 to 1.6 grams per kilogram, adjusted to your calorie needs. That is about 0.54 to 0.73 grams per pound. The US minimum stays at 0.8 grams per kilogram, about 0.36 per pound.

Can my dad eat more protein if he has kidney disease? Not without his kidney doctor. PROT-AGE says people with severe kidney disease who are not on dialysis may need to limit protein.

Is store beef unsafe to eat? No receipt in this post says so. What they show is how few companies buy the cattle, and that you never meet the people who raised them.

How do I find a rancher near me? Ask neighbors and friends who buy beef by the half or the quarter. Then call the ranch and ask if you can come out and see it.

Who do you become?

You become the daughter who knows her mom's number.

It is a Sunday night in October. You set her plate down, and you know whose ranch the beef came from.

You did the math once, at the kitchen table, on a sticky note that is still on the fridge.

That is the whole change. It took one evening.
