Mitochondria and the Anti-Aging Role Of Lipid Replacement Therapies

Introduction

There is a simple arithmetic to human life that holds deep insights into health and disease—the rate of our cell generation minus the rate of our cell loss determines the growth or degeneration of a tissue.

Recent evidence indicates that the interplay between our mitochondria, mitophagy (the removal of impaired mitochondria by a specialised version of the autophagy pathway by delivering mitochondria to the lysosomes for degradation) and autophagy links aging to health or disease.[1]

Do Diets Leave You Micronutrient Deficient?

The shortage of essential micronutrients in the human diet has been linked to multiple health and disease related problems. Dr Bruce Ames has described how the micronutrient triage theory can account for disease induction and more rapid levels of poor quality aging. I have written about the expensive urine myth and how the failure to recognise the differing demands placed by cells at different times can lead to altered and compromised health function.

This paper looks at the nutritional intake of people following a weight loss diet.[1] Based on the USA figures, the authors say that about 1/3 of the population are following some sort of weight loss orientated nutritional programme. The study looked to see if 27 micronutrients could be ingested in sufficient quantities whilst following 4 well known diets to meet minimum RDA levels as determined by the USA regulatory body the FDA.

If Genes Are Protected By Nutrients – How Much Should We Eat?

Prof Bruce Ames has developed the concept of Triage consumption, where micronutrient needs and availability may not always be in synchronicity and has recommended that a larger overall consumption of micronutrients on a daily basis be considered a judicious way to limit DNA damage associated with aging and disease.

I have proposed that the expensive urine criticism is perhaps one of the most damaging of slights, and that Victor Herberts slur on the use of increased exogenous nutrients via supplementation has created more damage to human health than it has saved. A paper out in the American Journal of Nutrition, May 2010 has added some further clarity to this discussion.[1]

Anti-Aging – Look & Function Years 12 years Younger

The idea we can live forever is still a fantasy, but living with reduced rates of mortality and morbidity are very achievable and represent perfectly reasonable aims. Outside of aesthetic objectives remaining a viable member of society and family through continued avoidance of disease and management of overall productive energy are perfectly fair aims.

The Journal Archives of Internal Medicine published a compelling study in April, looking at the effects of lifestyle habits on the risks for future mortality in the British population.[1]

The key elements – smoking, exercise, diet and alcohol were tracked in a prospective cohort study design. Just under 5000 people with an average age of 44 were followed for 20 years.

Expensive Urine or Effective Triage?

Victor Herbert, the outspoken Harvard nutrition scientist, was quoted by the United States well read Time magazine in a famous 1992 cover story about nutrition as saying that vitamins just gave one “expensive urine.”

This one liner has acted as a simple rebuke to the consumption of additional nutrients as food supplements – or at least the water soluble ones. It is repeated by the medical community wedded to the model that food will supply all we require, and by the skeptics who seek an easy one liner to dismiss thousands of research papers that contradict this simplistic and invalid statement.

Lactobacillus GG: A Potent Immune Regulator Effective in Many Disorders

front-cover-Focus-sept-2009New Research Reveals Probiotic’s Anti-Toxin, Anti-Inflammatory, Immune Boosting Properties

Lactobacillus GG is the most prolifically researched probiotic in the world—over 400 studies have been published that document its remarkable immune-modulating properties.This unique immunobiotic was isolated from a healthy human in 1985 by a team of two Tufts University researchers,Barry Goldin, M.S., Ph.D. and Sherwood L. Gorbach, M.D. They spent nearly a decade testing organisms until they discovered one that was a potent antimicrobial, survived stomach and bile acid, and was very, very sticky—it adhered well to the gut mucosa.

Oestrogen Metabolism is Beneficially Manged By Plant Extract (DIM)

00bookDiindolylmethane (DIM)
A phytonutrient and plant indole found in cruciferous vegetables including broccoli, brussels sprouts, cabbage, cauliflower and kale, with potential antiandrogenic and antineoplastic activities. As a dimer of indole-3-carbinol, diindolylmethane (DIM) promotes beneficial oestrogen metabolism in both sexes by reducing the levels of 16-hydroxy oestrogen metabolites and increasing the formation of 2-hydroxy oestrogen metabolites, resulting in increased antioxidant activity. Although this agent induces apoptosis in tumor cells in vitro, the exact mechanism by which DIM exhibits its antineoplastic activity in vivo is unknown. Check for active clinical trials using this agent. (NCI Thesaurus)

Brain Health- Potential for Improvement with Vit D and Curcumin

Comment:

cover-mediumA combination of vitamin D3 and curcumin, from tumeric, may boost the immune system, and help it clear the protein plaques linked to Alzheimer’s, says a new study.

The new data, published in the Journal of Alzheimer’s Disease, may lead to new approaches in preventing Alzheimer’s by using vitamin D3 alone or in combination with natural or synthetic curcumin to boost the immune system in protecting the brain against beta-amyloid.

The Immune System and the Impact of Zinc During Ageing

The trace element zinc is essential for the immune system, and zinc deficiency affects multiple aspects of innate and adaptive immunity. There are remarkable parallels in the immunological changes during aging and zinc deficiency, including a reduction in the activity of the thymus and thymic hormones, a shift of the T helper cell balance toward T helper type 2 cells, decreased response to vaccination, and impaired functions of innate immune cells. Many studies confirm a decline of zinc levels with age. Most of these studies do not classify the majority of elderly as zinc deficient, but even marginal zinc deprivation can affect immune function. Consequently, oral zinc supplementation demonstrates the potential to improve immunity and efficiently down regulates chronic inflammatory responses in the elderly. These data indicate that a wide prevalence of marginal zinc deficiency in elderly people may contribute to immunosenescence.

Multivitamin use and telomere length in women

Background: Telomere length may be a marker of biological aging. Multivitamin supplements represent a major source of micronutrients, which may affect telomere length by modulating oxidative stress and chronic inflammation.
