Things worth knowing

• One ounce (about 19 halves, 28 g) has 196 kcal / 820 kJ, and a single pecan half about 10 kcal / 43 kJ.
• Roasting adds little: dry-roasted pecans list 710 kcal and oil-roasted 715 kcal per 100 g, partly because roasting removes the little water they contain.
• Pecans have more energy and fat per 100 g than walnuts (654 kcal), but walnuts have about two-thirds more protein (15.2 g vs 9.2 g).
• One ounce supplies about 1.3 mg of manganese (55% of the Daily Value), 0.34 mg of copper (38%) and 2.7 g of fibre.
