For their role in heart and cardiovascular health, walnuts have received a great deal of attention in recent years. However, they aren’t the only healthy nut option around. When it comes to nutrition, pecans can go toe-to-toe with walnuts in the way they protect the heart and mind, support weight loss, and promote weight management. In fact, pecans may even have the edge over walnuts as the healthier nut…
Pecans vs Walnut Breakdown
In one corner, we have pecans. In every ounce, or about 19 pecan halves, you consume just under 200 calories. That same ounce delivers nearly 27% of your recommended daily intake of heart healthy mono- and polyunsaturated fats. A single ounce serving of pecans is low in carbs weighing in at 3.93g, or about 1% your daily value. One ounce does, however, provide 5% of your daily protein recommendation. Plus, pecans are also loaded with vitamins A, B, and E, potassium, magnesium, immune-boosting zinc, and powerful antioxidants.
In the other corner, we have walnuts. One ounce of walnuts has 185 calories, 24% of your unsaturated fats with heart-protecting omega-3 fatty acids, 3.89 carbs per ounce, and a whopping 9% of your daily protein. Like pecans, walnuts feature vitamins A, E, and B vitamins like folate. They’re also mineral rich with important antioxidants.
