Pecan halves are full of healthy mono and polyunsaturated fats and as a part of a diet, can reduce cholesterol. There is a lot of vitamin A, vitamin B and a little less of vitamin E, but still enough to maintain a healthy intake. Pecan halves are worth a try if you’re trying to add supplements to your diet in a delicious way and are also a great source of calcium for those who can’t drink milk or eat products that contain lactose. Many people will recognise the flavour from a coffee cake - the combination is sublime.
