The darker the better, as in buckwheat honey, because the darkest honeys contain the most antioxidants.
We like a brand called Some Honey, which markets raw, natural, unadulterated buckwheat honey in 5 lb. jugs from Wisconsin for about $13 at Fruitful Yield stores in Illinois. The aroma is distinctive, oddly reminiscent of a barn, which is why we jokingly refer to this stuff as Illinois cow shit honey.
Steven Pratt points out that honey "contains at least 181 known substances, and its antioxidant activity stems from the phenolics, peptides, organic acids, and enzymes. Honey also contains salicylic acid, minerals, alpha-tocopherol, and oligosaccharides." The latter "increase the number of 'good' bacteria in the colon, reduce levels of toxic metabolites in the intestine, help prevent constipation, and help lower cholesterol and blood pressure."
Pretty impressive qualities, courtesy of the bees.
Pratt recommends 1 to 2 teaspoons multiple times per week. We like it on toast, in tea, and on baking day in a bread recipe.
