Leaner than its reputation in the fresh cuts — and far worse than its reputation once processed.
Pork's reputation is shaped almost entirely by bacon and sausage, which is unfair to
the fresh meat. A pork tenderloin is comparable to skinless chicken breast in fat content.
Pork belly is not.
The distinction that actually matters here is fresh versus
processed. Bacon, ham, salami and sausage are preserved with salt and nitrites, and the
evidence linking processed meat to bowel cancer and heart disease is considerably stronger
than for fresh pork.
Pork is also the best common source of thiamine (vitamin B1) by a
wide margin.
Per 100g cooked, average cut. Tenderloin runs near 143 kcal; belly runs far higher.

Tenderloin and loin are the lean cuts. Belly, shoulder and ribs are
not. Almost all the nutritional argument about pork is really an argument about which cut you
bought.
Modern pork does not need to be grey. Cooked to 63°C and
rested, it is safe and still slightly pink. Overcooking is why pork got its reputation for
being dry.
Treat bacon as a flavouring, not a protein. Two rashers to
season a dish is very different from a plate of it.
Shoulder rewards slow
cooking the way mutton does — hours at low heat turn a cheap cut into the best
thing on the table.
Thiamine is the standout. Pork contains several times more than most other meats,
and thiamine is required to convert carbohydrate into usable energy. Deficiency produces
fatigue, irritability and cognitive fog long before it produces the classic disease.
On processed pork: nitrites used in curing can form N-nitroso compounds in the gut, which is
the leading explanation for the bowel cancer association. That mechanism does not apply to
fresh pork.
Processed pork: bacon, ham and sausage are classified separately
from fresh meat by cancer research bodies. Occasional rather than routine is the sensible
line.
High blood pressure: cured pork is very high in sodium.
Gout or high uric acid: all meat contains purines, and organ
meats most of all. Meat and seafood purines trigger flares far more reliably than plant
purines do.
Kidney disease: protein load often needs limiting. This
needs your doctor's numbers, not a general rule.
Pregnancy: cook all
meat through — no pink — and avoid liver because of its vitamin A content.
