Each 100g provides 21.2g protein (42% DV), supplying all essential amino acids. Daily consumption supports muscle protein synthesis, especially when combined with resistance training. The high protein also increases satiety, helping control appetite.
Zinc at 3.81mg (35% DV) per 100g activates over 300 enzymes and supports T-cell function. Regular intake maintains adequate zinc status, crucial for immune response and tissue repair. However, chronic high zinc (above 40mg/day) can interfere with copper absorption, leading to deficiency.
At 692 kcal per 100g, daily consumption without adjusting other calories can lead to a surplus. Over a week, eating 200g daily adds ~9,688 kcal, potentially causing ~1.3kg fat gain. The 8.3g fat per 100g (11% DV) includes saturated fat, which may raise LDL cholesterol if consumed in excess.
With zero carbs and a glycemic index of 0, this steak does not spike blood glucose. The protein and fat slow gastric emptying, providing steady energy. This makes it suitable for low-carb diets, but lacks fiber, so pair with vegetables for digestive health.
Verdict
Daily beef flank steak can be part of a healthy diet if portions are controlled (e.g., 100g) and balanced with fiber-rich foods. But its high calorie density and saturated fat mean it's best limited to a few times per week for most people.
