Beef Is Last of 11 Food Groups on Calcium per Calorie

The six beef rows we hold run from 6.06mg of calcium per 100 calories down to 1.43mg. The median of the other 175 foods on this site is 26.02mg — four times the best beef and eighteen times the worst. The distance from beef's ceiling to everyone else's middle is 19.96mg, which is more than four times the entire 4.63mg spread inside the category. All figures are USDA FoodData Central rows.

That is an unusual shape for a nutrient. Normally picking the right food inside a group matters more than picking the group. Here it is the reverse, and by a wide margin.

How much calcium is in beef?

Between 3.7mg and 12mg per 100g, depending on the cut — and between 1.43mg and 6.06mg per 100 calories. Raw grass-fed ground beef is the highest on both bases. Boneless choice ribeye is the lowest per calorie, because it carries the same small amount of calcium across 291 calories per 100g.

The category's best is below every other category's middle

Beef Products has a median of 2.9mg of calcium per 100 calories, last of the eleven USDA food groups we hold enough rows to rank. Its ceiling, 6.06mg, is lower than the median of all ten others. Cereal Grains and Pasta is tenth at 7.4mg. Poultry is ninth at 8.9mg.

Ranking a group by its median rather than its best matters, because one exceptional row can carry a whole category. Legumes sit fourth on a median of 26.0mg while holding tofu at 474.3mg — tofu is set with calcium salts, and it is not representative of a bean. Beef has no such row. Its best and its median are 3.2mg apart.

What 100mg of calcium costs in beef

Reaching 100mg of calcium — a tenth of the adult Daily Value — takes 833g of raw grass-fed ground beef, which is 1,650 calories. From boneless ribeye it takes 2,398g and 6,978 calories. 100g of raw kale carries 254mg for 35 calories.

Those beef numbers are not a recommendation, and nobody should read them as one. They are the arithmetic of a food that is not a calcium source, stated in portions so the scale is visible. A per-100g table showing "12mg" does not convey that the portion required is most of a day's energy.

151 of the other 175 foods beat the best beef row

151 foods clear 6.06mg of calcium per 100 calories. That is 86% of everything else we hold. The leaders are not close. Per 100 calories, all raw: kale 725.7mg, collard greens 725.0mg, arugula 640.0mg, bok choy 476.2mg, tofu 474.3mg — every one more than seventy times the best beef row.

The 24 foods that do not beat it are mostly oils, other meats and refined grains — the same places you would expect to find a calcium floor. Our full calcium-per-calorie ranking has the top of that list, where this post has the bottom.

Beef is not bad at minerals. It is bad at this one.

Raw beef liver is 5th of 179 foods on zinc per 100 calories at 2.96mg, and raw grass-fed ground beef is 10th at 2.30mg. The liver row also gives 15.11g of protein and 3.63mg of iron per 100 calories. On those three columns beef is genuinely near the top.

A single-nutrient ranking is a single question, and this one asks something beef was never going to answer well. The honest reading is narrow: if calcium is what you are short of, no cut of beef moves the number, and the food group you want is dairy or leafy greens. Everything else beef is good for is untouched by this table. Beef liver vs chicken breast and ribeye vs sirloin compare them on the columns that do separate cuts.

One thing to know about these rows

Five of our six beef rows are raw; the corned beef row is cooked. Cooking concentrates minerals by driving off water, so the cooked row is not strictly comparable to the five beside it. Corned beef sits third per calorie partly for that reason and partly because curing adds sodium, not calcium.

It does not change the finding. Even generously adjusted, no beef row approaches the 26.02mg median of the rest of the site, and the gap this post is about is an order of magnitude, not a rounding difference.

Where each of these rows lives

Each row in the first table has a page of its own, and three carry most of this post — ground beef, beef liver and kale sit at the top, the middle and the far end of the calcium column.

Nobody tracks calcium, and that is the problem

Calcium is the nutrient people assume they are getting. It does not show up on most food labels in a way anyone reads, it is not one of the three macros, and a day can go by with 200mg in it without anything feeling wrong. You only find out years later.

Sunn keeps the running total without being asked. Log the steak and the salad the way you would text a friend, and the calcium, iron and zinc columns fill themselves in behind the macros — so a month of low calcium is something you can see rather than something you find out about.
