The risk of micronutrient deficiencies in old age
Since older people often do not process food well, old age may be considered a risk factor for inadequate micronutrient uptake. In the course of the natural aging process, several bodily functions deteriorate. An insufficient supply of micronutrients to the organism can accelerate the natural aging process and aggravate the decline of cell renewal processes, immune defense, eyesight and hearing, and cognitive performance. Further, the presence of chronic diseases like cardiovascular disease, osteoporosis, diabetes and cancer can increase micronutrient requirements. It is therefore all the more necessary to ensure that older people receive an optimal supply of vitamins, minerals, trace elements and essential fatty acids. However, many older people are a long way from consuming the recommended daily amounts, even in highly developed industrial nations.
Vitamin C and the common cold
In 1970, Linus Pauling outlined in a book his own experience with vitamin C and the reasons he believed gram doses of vitamin C would improve the immune system. Written at a time when natural therapies were becoming increasingly popular as alternatives to conventional pharmaceuticals, the message resonated with the public with such intensity that vitamin C will forever be linked with the prevention and treatment of the cold. However, research studies on vitamin C and colds have often been poorly conducted, generating controversial results.
A new study from Finland reports that low blood vitamin D concentrations in childhood seem to increase occurrence of atherosclerosis in adulthood.
A new review from Iran suggests that vitamin E supplementation can have significant anti-inflammatory effects.
