How do Omega-3s work?
Inside your favorite kinds of nuts — walnuts, almonds, pecans and others — you’ll find many vitamins, minerals and other compounds your body needs for good health. There are the antioxidants found in vitamin E; several essential minerals such as magnesium, selenium, copper and manganese; and even fiber for more effective digestion. Thiamin, niacin, folate, phosphorus and zinc are all found in nuts.
Researchers believe that omega-3 fatty acids may help reduce the risk of heart disease by making the blood less sticky and less likely to form dangerous intravenous or arterial clots. Studies have also shown that omega-3s may lower the risk of stroke and prevent arthritis. In addition, there’s good evidence that omega-3s can increase HDL (good cholesterol), further reducing the risk of stroke and heart disease.
The omega-3s found in fish oil are thought to be responsible for the significantly lower incidence of breast cancer in Japanese women as compared to women in the United States. This may be because omega-3 fatty acids inhibit the tumor growth that is promoted by the acids found in other fats, such as corn and safflower oils.
Finally, the brain itself is composed of a whopping 60 percent fat. It too needs omega-3s to help build and maintain tissue. Brain function itself may be at stake: in treating major depression, for example, omega-3s seem to work by making it easier for brain cell receptors to process mood-related signals from neighboring neurons.
What are good sources of omega-3s?
Omega-3 fatty acids are plentiful in cold-water fish such as mackerel and salmon. They’re also found in walnuts, canola oil, soybean oil, tofu and leafy green vegetables. Which would you rather sprinkle on your morning cereal or grab for a nutritious snack?
Walnuts are a delectable, convenient alternative to fish, tofu and leafy greens. In fact, just a handful of walnuts provides as much omega-3s as a comparable serving of salmon.
