Have you considered the Nordic diet?

The wholesome and delicious Nordic Diet

Scientists at the University of Copenhagen in Denmark have launched an expensive programme to identify and test products from northern climes that could be part of a new healthy, Nordic diet.

Research by Elling Bere of Agder University in Norway, has indicated that native berries, such as blueberries, cowberries and cloudberries contain as much unsaturated healthy fat as fish per unit of energy.

He also determined that they were rich in antioxidants, which reduce the levels of harmful free-radicals in cells. Free radicals are known to cause heart disease, stroke and cancer.

It’s believed foods from the north could soon be replacing the Mediterranean diet currently top of nutritionists’ list for a long, vigorous life.

Instead of olive oil, citrus fruit, tomatoes and pasta, we could soon be shopping for elk, rapeseed oil, cowberries and cloudberries.

It has to be said, though, that the Danish authorities are not exactly neutral in promoting their own products. Whether European and American consumers will abandon their pizzas and Nicoise salads for soused herring remains to be seen.

However, it has been said that although foods of the south are low in saturated fats, the Med diet produces a lot of plump and overweight people.

Traditional Nordic diets are high in in fish like, salmon, trout, cod and herring, all rich in unsaturated omega-3 fatty acids. The leaner qualities of northern foods, such as elk and reindeer, promote leaner people over time.

Another pointer in favour of Nordic foods is that they are more convenient to produce in colder climates, like Britain, than alternatives from the Mediterranean.

Things are looking up for the northern lifestyle.

In a counter-intuitive article in the New York Times, which quotes researchers in Germany and Boston, exercise and antioxidants don’t mix. “If you exercise to improve your metabolism and prevent diabetes, you may want to avoid antioxidants like vitamins C and E.”

Dr. Michael Ristow, a nutritionist at the University of Jena in Germany, said, “If you exercise to promote health, you shouldn’t take large amounts of antioxidants. … antioxidants in general cause certain effects that inhibit otherwise positive effects of exercise, dieting and other interventions.”

It seems that exercise encourages muscle cells to metabolize glucose by combining carbon atoms with oxygen. In the process, highly reactive oxygen molecules are released which then attack various parts of the body damaging the tissues.

The Jena team found that in the group taking antioxidant vitamins, like vitamins C and E, there was no improvement in insulin sensitivity and almost no activation of the body’s natural defence mechanism against oxidative damage.

Once again, what we thought was done and dusted has been called into question by more research.

However, the advice does not apply to fruits and vegetables, Ristow said, even though they are high in antioxidants, it may be that other substances they contain outweigh any negative effect.

Andrew Shao of the Council for Responsible Nutrition, a trade association of dietary supplement makers, said, “I wouldn’t change recommendations for anyone based on one study. This is one small piece of the puzzle.”

The amount of oxidative damage increases with age, and according to one theory of aging it is a major cause of the body’s decline.

The findings appear in this week’s issue of The Proceedings of the National Academy of Sciences.
