The Nordic Diet? Is it Healthy?

The traditional diets rich in butter, meat, potatoes and cream of the Nordic countries are changing and so is the health profiles of Sweden, Denmark, Norway and Finland. Fruit and vegetable intake was low due the lack of availability and short growing seasons.

  • In Finland, a national public health program resulted in heart disease mortality that plummeted 55 percent among men and nearly 70 percent among women.
  • In Norway, deaths from heart disease have declined sharply by 40 percent in the 40 to 49 years old age group  since the late 1970’s.
  • Life expectancy has increased in Sweden continues to rise. Cancer rates remain significantly less of a threat in this geographical area according to World Health Organization statistics.

Could their diet changes be one of the factors responsible? Take a look at the Nordic Diet.

The Search for a “Healthy Diet”

By Sally Feltner, PhD, MS, RDN  March 18, 2017

Does your doctor often say, “Watch your diet” or have you noticed that most diet advice recommends that you eat “a healthy diet.” But honestly, why should we believe anything nutrition scientists have to say at this point? There’s been little consistency in the advice we’ve been given for decades. We have gone from hearing advice, to advice, that contradicts the first advice, and now we’re back in some cases to the original advice again. A lot of that advice has even turned out to be actually harmful. Remember the recommendation in the middle 1990’s to switch to trans-fat laden margarines

When I first began to study nutrition in the 1980’s, we knew little about the causes of cancer, heart disease, and diabetes as well as dementia, bone loss, you name it. I have been through the low fat, the low carb, the high fiber, the whole grain, the low fat dairy eras etc. . as well as just about any fad diet or gimmick you could think of. What have we learned? Not much. We are still searching for the perfect diet, the magic supplement, the best “superfood” to keep us healthy and increase our lifespan.

This is not to say that there have not been any important discoveries. Back in the early days of nutrition research, the discovery of vitamins and minerals saved thousands of lives. We have clearly eliminated the deficiency diseases, at least in developed countries, of scurvy, beriberi, pellagra as well as the prevention of goiter (iodine). More recently, we learned to prevent the devastating effects of neural tube defects with the fortification of folate in grain products.

Recently, the latest rankings of the U.S. News and World Report 2017 Best Diet Rankings were published. The three best diets overall as well as the three best diets for healthy Eating were:

These three diets are important because each one has been shown be associated with positive health benefits. The DASH diet benefits are associated with blood pressure control and thus an decreased heart disease risk. The Mediterranean diet has heart benefits and improved cognitive (Alzheimer’s) health, and the aim of the MIND diet is a combination of the other two diets – the DASH and Mediterranean that zeroes in on foods in each that specifically affect brain health. Both the Mediterranean diet and the MIND diet won honors in easiest to follow, important with any diet attempt. There is no sense to attempt a diet you cannot feasibly follow. It  should not be a “diet”, but a lifestyle.

Nutrition professionals need to be careful about how we support what we say. Instead of “we know,” we have to just admit that “we think.” People often become resentful when we pretend to know more than we really do and tell them what to eat and then have to backtrack on that advice years later.

Fortunately, there are other says to assess diet quality. For now, we also can rely on the observational studies that look at the traditional diets of certain populations and cultures have shown us the many lifestyles factors including diet that confer health and longevity.

Epigenetics and the Microbiome?

Methylation of DNA in Epigenetics

Methylation of DNA in Epigenetics

Epigenetics is a relatively new approach on how the our environment affects our DNA, mainly  the expression of our genes.  The way diet affects our health may be through the many species of bacteria that live in our intestines or microbiome. See a previous post on epigenetics HERE. and the microbiome HERE.

For new research on the association between the two:

Does Exercise Increase Weight Loss?

011a

This study tells us that there is a limit on the amount of exercise that will increase energy expenditure. However, it offers some good information on what else exercise can do for us physiologically.  Therefore, eat less and move more may not be the whole solution for  weight loss, but it is still good advice for a healthy lifestyle.
