German seniors show vitamin deficiencies – Study

This study of German seniors demonstrates once again the value of a good diet. The fact that many were inactive and frail seems also to suggest that we continue to need to move and exercise as we age, perhaps more than when we are  younger. Eat less, move more, live longer.

One in two persons aged 65 and above has suboptimal levels of vitamin D in the blood. This is the conclusion of an investigation conducted by researchers at the Helmholtz Zentrum München, as part of the population-based KORA-Age study in the region of Augsburg. Moreover, as the authors of the study report in the peer-reviewed journal ‘Nutrients,’ one in four older adults has suboptimal vitamin B12 levels.

Since more than 30 years, the KORA Cooperative Health Research platform has been examining the health of thousands of people living in the greater Augsburg area in Southern Germany. The aim of the study is to understand the impact of environmental factors, lifestyle factors and genes on health. “In this context, we were also interested in examining the micronutrient status of older adults, including vitamins” explains study leader Dr. Barbara Thorand of the Institute of Epidemiology (EPI), Helmholtz Zentrum München. “So far, in Germany, research data on this topic has been relatively thin on the ground.”

Overall, the scientists examined blood samples of 1,079 older adults, aged 65 to 93 years from the KORA study*. Their analysis focused on levels of four micronutrients: vitamin D, folate, vitamin B12 and iron.

“The results are very clear,” explains first author Romy Conzade. “Fifty-two percent of the examined older adults had vitamin D levels below 50 nmol/L and thus had a suboptimal vitamin D status.” The scientists also observed shortages with regard to some of the other micronutrients. Notably, 27 percent of older adults had vitamin B12 levels below the cut-off. Moreover, in 11 percent of older adults, iron levels were too low, and almost nine percent did not have enough folate in their blood.

EPI director Professor Annette Peters puts the data into context: “By means of blood analyses, the current study has confirmed the critical results of the last German National Nutrition Survey (NVS II)**, which revealed an insufficient intake of micronutrients from foods. This is a highly relevant issue, particularly in light of our growing aging population.”

Are dietary supplements the way forward?

The majority of older adults with suboptimal vitamin levels had in common that they were very old, physically inactive or frail. Special attention should, therefore, be paid to these groups with a higher risk for micronutrient deficiencies, explain the researchers.

“Our study also shows that regular intake of vitamin-containing supplements goes along with improved levels of the respective vitamins,” says Barbara Thorand. “However, vitamin-containing supplements are not a universal remedy, and particularly older people should watch out for maintaining a healthy and nutritious diet.”

In this context, the authors say their next objective is to continue investigating the metabolic pathways that link supplement intake, micronutrient status and disease states.

Organ meats – Benefits and risks – MNT

Organ meats are sometimes referred to as “offal.” The word offal derives from the term “off fall,” referring to any part of an animal that falls away when it is butchered, such as the tail, feet, and testicles.

In the United States, organ meats include all things that are distinguished as offal. On the other hand, most meats Americans are used to eating are muscle meats, while organ meats are not considered a staple of the Western diet.

Organ meats carry some risks, however, as well as benefits, when they are consumed, despite their nutritional value.

Fast facts on organ meats:

  • Organ meats are very high in some vitamins and nutrients.
  • There are issues with harmful bacteria in intestines if not cleaned properly. Also, brain meat has been known to transmit rare diseases, such as Mad Cow Disease.
  • Despite the vitamin content, culturally in the U.S., organ meats are not considered as important a part of a dietary plan, as traditional muscle meats.

What is organ meat?

Chicken liver is a type of organ meat or offal.

There are several different types of organ meats, some of which are better known than others including:

Vitamin D and Your Body – Harvard

Earlier this week I wrote about Vitamin D affecting waist reduction in a study. It is complicated to work out all the factors that affect our Vitamin D level yet this is a very valuable vitamin in our arsenal of good health.

The greatest natural source of Vitamin D

The greatest natural source of Vitamin D


Harvard Healthbeat
says, “The process by which the body makes vitamin D is complex. It starts when the skin absorbs rays in the invisible ultraviolet B (UVB) part of the light spectrum. The liver and the kidneys also participate to make a form of the vitamin that the body can use.
“A number of factors influence a person’s vitamin D levels.

Here are six important ones.
1.
Where you live. The farther away from the Equator you live, the less vitamin D–producing UVB light reaches the earth’s surface during the winter. Residents of Boston, for example, make little if any of the vitamin from November through February. Short days and clothing that covers legs and arms also limit UVB exposure.

2.
Air quality. Carbon particles in the air from the burning of fossil fuels, wood, and other materials scatter and absorb UVB rays, diminishing vitamin D production. In contrast, ozone absorbs UVB radiation, so pollution-caused holes in the ozone layer could end up enhancing vitamin D levels. For those of us who life In the U.S. just being out in the sun is not sufficient to get adequate Vitamin D during the winter because of the sun’s acute angle to the earth.
