Nutrition Snapshot
- About 36 grams of protein and 3 micrograms of vitamin B12 in one plate, from beef, more than a full day’s worth of B12 in a form that absorbs.
- Beef also brings about 5 milligrams of iron and a large dose of zinc, and the broccoli and mushrooms bring about 5 grams of fiber.
- The trade-off: even lean beef carries saturated fat, about 7 grams a plate here. The card shows the figures, and the notes show how to lower it.
A pound and a quarter of lean ground beef is mixed with eight ounces of mushrooms chopped very fine, rolled oats, an egg, grated onion, and Dijon. The mix is shaped into eight small patties and cooked in a skillet until browned and cooked through. A bag of frozen broccoli steams alongside.
Two patties and a pile of broccoli is a plate, and the patties are soft enough to cut with a fork, because the mushrooms keep them moist.
Why These Patties Are Great for B12 After 65
Vitamin B12 is absorbed with the help of stomach acid, which frees it from the protein it arrives in, and stomach acid falls with age. It falls further with the acid-reducing medications that a large share of people past 65 take every day for heartburn.
So B12 from food is absorbed less well exactly when it is needed most. Low B12 shows up as tiredness, numb or tingling feet, unsteadiness, and a memory that has slipped.
Food still matters. The richer the meal is in B12, the more gets through even when absorption is poor, and beef is one of the richest common sources.
A Day’s B12 in Two Patties
Two of these patties carry about 3 micrograms of vitamin B12, more than the 2.4 micrograms a day an adult needs. They also carry about 36 grams of protein and a good dose of iron and zinc, two other nutrients that get short after 65.
A blood test decides whether a supplement is needed on top, and the evidence on that is on the supplement side of this site. Which other foods carry the nutrients older adults run short on is in Protein Density: Eating Enough When Appetite Is Small.
Why the Antacid Matters
Proton pump inhibitors and the older acid blockers are among the most widely used medications after 65, and most people take them for years. They do their job by cutting stomach acid, and less acid means less B12 freed from food. Studies of long-term users find low B12 in a meaningful share of them, and the risk rises with the dose and the years.
Nobody should stop a prescribed medication over this. The practical response is a B12-rich food most days, a blood test at the next checkup, and a supplement if the number says so. The supplement form does not need stomach acid to absorb.
Mushrooms Make the Patty Soft
Chopped mushrooms mixed into ground meat hold moisture through cooking, so the patties stay soft and juicy instead of drying into pucks, and they stretch a pound of beef into eight patties. For teeth that struggle, the mushrooms also mean a patty that cuts with a fork and needs little chewing.
Cooked patties keep four days and freeze for two months, and one reheated with a spoon of the broccoli is a small dinner for one.

Beef and Mushroom Patties With Broccoli
Ingredients
Equipment
Method
- Mix the mushrooms, beef, oats, egg, onion, mustard, thyme, salt, and pepper in a bowl until just combined. Let it sit 5 minutes so the oats soften. Shape into 8 patties about 3 inches across and 3/4 inch thick.
- Heat the oil in a large skillet over medium heat. Cook the patties until browned underneath, about 5 minutes, then turn and cook until browned and cooked through with no pink in the center, 5 to 6 minutes more (160 degrees F on a thermometer).
- Meanwhile, steam the broccoli until hot and tender, about 5 minutes, or microwave it in a covered dish. Toss with the oil and lemon.
- Serve 2 patties with a quarter of the broccoli. Cooked patties keep 4 days in the refrigerator or 2 months frozen.

Notes

Let us know how it was!Gluten Free
Beef, mushrooms, egg, onion, and broccoli are naturally free of gluten. Rolled oats are naturally free of gluten but often milled alongside wheat, so for people with celiac disease the oats need a gluten-free label. The Dijon mustard should list no malt vinegar or wheat. People who avoid gluten by preference can use any oats.
