Nuts for heart and Weight control
Nuts are calorie rich – almost 200 calories per ounce. More than three-quarters of the calories come from fat, its ‘good unsaturated fat’, not the artery clogging ‘saturated fat.’ In walnuts, 93 % of the fat is unsaturated, in almonds 90%. This is almost close to olive oil – the lingua franca of Mediterranean diet. Unsaturated fats are made up of various fatty acids. Walnuts are rich in alpha-linolenic acid – the higher its level in blood, the lower the risk of stroke. It is converted in the body into omega 3 fatty acid – the same kind that comes from fish oil.
Research indicates that people who consume nuts tend to weigh less than those who don’t munch on nuts. The nut strategy is to avoid nuts as snacks (you may eat large amounts!) but to consider them as part of the planned meal. Better still, substitute nuts for foods rich in saturated fats. Nuts are quite filling and they satisfy your appetite fast. If you happen to gain weight by eating lots of nuts, that’s bad for your heart.
A number of studies have extolled nut’s virtues and have brought a better understanding of its benefits. Some nuts in the US are now allowed to have FDA approved labels mentioning the heart benefits of the nuts. Besides healthy fats for the heart, nuts come packed with folate and B vitamins which lower the blood levels of homocysteine. Minerals like copper, potassium and magnesium are closely linked to heart health. Vitamin E is also cardioprotective. Phytochemicals like sterols, ellagic acid, polyphenols, and saponins may act as antioxidants and lower the cholesterol level. Nuts have lots of arginines, which helps in nitric oxide production leading to healthy artery walls which becomes more flexible and less prone to blood clots.
