BUT WAIT, THERE’S MORE

Although lifestyle changes have contributed to the increase in the prevalence of chronic diseases in developing countries, obesity, T2DM, and other diseases associated with insulin resistance are increasing in developed countries where there have been no recent changes in diet or physical activity.

WHAT ARE POPs?

• Persistent organic pollutants (POPs) are characterised by their

ability to persist in the environment, their low water and high lipid solubility and their bio-magnification in the food chain

• POPs include – Organochlorines, DDT, PCBs, dioxins,

dibenzo-p-furans (PCDFs), polybrominated biphenyls (PBB), hexachlorobenzene (HCB)

• POPs can travel great distances and can end up in countries
• ther than those in which they were produced

IS METABOLIC SYNDROME AN ADAPTIVE RESPONSE TO MITOCHONDRIAL DAMAGE?

The development of obesity, hyperglycaemia, and hypertension might be viewed as compensatory responses to the decreased mitochondrial unit of the body: maintaining core temperature by decreasing heat loss and increasing heat production, increasing the availability of fuels, and stimulating energy metabolism as a whole through activation of the sympathetic nervous system.

THE FAT LOSS PARADOX

It has been suggested that weight loss induces a significant increase in plasma organochlorine levels in humans. This rise in plasma

• rganochlorine concentration has also been

associated with a decrease in T3 concentration, resting metabolic rate and skeletal muscle capacity for fat oxidation.

FAT LOSS PATIENTS NEED SUPPORT TO PREVENT POPs DAMAGE

When fatty acids are released from adipose tissue, POPs are released simultaneously. This can damage mitochondria in endocrinologically active tissues such as the liver and muscle. Thus, POPs may decrease mitochondrial oxidative capacity in various organs.

GLUTATHIONE ESSENTIAL FOR DETOXIFICATION OF XENOBIOTICS

EVEN LOW EXPOSURE DEPLETES GLUTATHIONE

• Even at low doses POPs induce responses like phase I,

phase II, and phase III xenobiotic metabolism pathways.

• In particular, phase II glutathione (GSH) conjugation can

lead to chronic consumption and depletion of intracellular GSH.

• Intracellular GSH depletion can cause mitochondrial

dysfunction which is closely related to inflammation and ectopic fat accumulation and type 2 diabetes.

PCB DAMAGE REDUCED BY RESVERATROL

• Results from this study indicate that resveratrol reduces PCB

induced

• xidative

stress in adipose tissue while simultaneously enhancing Nrf2 signaling.

• This may have contributed to protection from PCB-induced

impairment of glucose and insulin tolerance.

• Supplementation with resveratrol may be a potential therapy

for populations with known PCB exposures to lower the risk

DYSBIOSIS TRIGGERS INFLAMMASOME ACTIVATION

OBESE MICROBIOME GOOD AT HARVESTING ENERGY

• Studies have confirmed that the obese gut

microbiome has an increased capacity to harvest energy from the diet influencing body weight, and to interfere with metabolic changes.

• Most recently, the transfer of intestinal microbiota

from human lean donors has been shown to increase insulin sensitivity also in men with metabolic syndrome.

MINIMISING TOXIC EXPOSURE

• Minimise consumption of large fish & shellfish

– Reduce consumption of farmed fish

• Reduce consumption of fatty meat – remove as much fat and skin as

possible

• Reduce consumption of full fat dairy products
• Wash or peel fruit and vegetables before eating
• Eat organic meat, dairy, fruit and vegetables when possible
• Drink purified or filtered water, avoid plastic bottles
• Use non-toxic cleaning agents
• Use non-toxic building materials, paints and carpets
• Use natural cosmetics, shampoos, nail polish & fragrances
• Use BPA free drink bottles and containers
• Wash clothing before wearing it
• Don’t overheat empty non-stick cookware (or don’t use it!)
• Allow fresh air into the home and vacuum regularly, leave shoes outside.

EXERCISE AND SAUNA HELPS CLEAR FAT-SOLUBLE TOXINS

A program known as the Hubbard Purification Rundown consisted of:

• Physical exercise for 20-30 minutes
• Sauna, 140-180°F

, done in 30 minute sessions for a total of 2.5-5 hours daily

• Increasing doses of niacin each day and a multivitamin
• Water and electrolyte (NaCl, K) replacement
• Oil, 1-8 Tbsp daily
• Balanced meals and adequate sleep

Ten electrical workers who did 3 weeks of this protocol were studied. They experienced a 7.8% drop in adipose pesticide levels and a 4.7% drop in PCB levels. In the 3 months after treatment ended, the pesticides continued to be cleared from the workers’ bodies. At the 3-month follow- up, the mean total drop in pesticides from pre-treatment levels for the treatment group was 21.2% (2.3% for PCBs).
