Beef flank steak and gout
Verdict: Beef flank steak is moderate purines — eat it in moderation, especially if your uric acid is high.
Beef flank steak is a moderately rich source of purines, containing 113.9 mg per 100 g in its boiled form. This places it in the moderate category for gout management, meaning it's not off-limits but does require mindful portion control. If you're in a daily maintenance phase (keeping total purine intake under 400 mg), a 100 g serving of flank steak fits reasonably into your day when balanced with lower-purine foods. However, during a gout flare, it's wise to avoid it temporarily. The cooking method matters: boiling keeps purine levels at 113.9 mg, while grilling raises them to 121.8 mg. Pairing any portion with plenty of water supports your kidneys in processing purines effectively. Think of moderate-purine meats as occasional rather than daily choices, and always listen to how your body responds.

Frequently asked questions
Can I eat beef flank steak if I have gout?
Yes, but in moderation. At 113.9 mg of purines per 100 g, it's moderate rather than high-risk, so a reasonable portion (80–120 g) can fit into a well-balanced day during maintenance. Avoid it during active flares and choose boiling or gentle cooking methods to keep purine levels lower.
Does the cooking method change how much purine is in flank steak?
Yes, it does. Boiling keeps purines at 113.9 mg per 100 g, while grilling raises them to 121.8 mg and roasting to 126.1 mg. Boiling or light sautéing are the gentler choices if you want to minimize purine intake from this cut.
How much flank steak is safe to eat in one meal?
A portion of 100–120 g (about the size of a deck of cards) is a reasonable serving during maintenance phases. This delivers roughly 115–140 mg of purines, leaving room in your daily budget for other foods. Always pair it with vegetables, whole grains, and plenty of water.
