Canola the new deep-sea fish

FIELD OF DREAMS: Scientists are developing canola varieties that produce omega-3 oils previously only available from deep-sea fish.

THE human body needs the omega-3 and omega-6 fatty acids for many purposes including brain and nerve function; our bodies cannot produce them – they come only from food.

But these polyunsaturated fats are also important as there is growing evidence they help lower the risk of heart disease.

And some studies even suggest they may also protect against Type 2 diabetes, Alzheimer’s disease, and age-related brain decline.

The sources of these remarkable oils are all food based, even though it is not yet known what proportion of the oils is optimal.

Omega-6 mostly comes from plant oils such as corn oil, soybean oil and sunflower oil, as well as from nuts and seeds.

Too much of these can contribute to inflammation and result in heart disease, cancer, asthma, arthritis and depression.
