Research on kale and cholesterol levels is especially interesting. Recent studies show that kale can provide you with some special cholesterol-lowering benefits if you cook it by steaming. The fiber-related components in kale do a better job of binding together with bile acids in your digestive tract when they've been steamed. When this binding process takes place, it's easier for bile acids to be excreted, and the result is a lowering of your cholesterol levels. Raw kale still has cholesterol-lowering ability—just not as much. Along these same lines, a recent study has examined the impact of 5 ounces of kale juice per day for 12 weeks in men with high blood cholesterol levels (above 200 mg/dL). Consumption of kale juice was determined to raise the HDL levels in these study participants, lower their LDL levels, and also improve their atherogenic profiles (which measured their likelihood of developing coronary artery disease). At WHFoods, we always encourage consumption of whole foods in their minimally processed forms. However, we also believe that this study on kale juice underscores the remarkable health benefits that can be derived from this cruciferous vegetable.
