The Skinny on Fats,

Quoted from : http://www.westonaprice.org/knowyourfats/skinny.html

And what about cholesterol? Here, too, the public has been misinformed. Our blood vessels can become damaged in a number of ways-through irritations caused by free radicals or viruses, or because they are structurally weak-and when this happens, the body's natural healing substance steps in to repair the damage. That substance is cholesterol. Cholesterol is a high-molecular-weight alcohol that is manufactured in the liver and in most human cells. Like saturated fats, the cholesterol we make and consume plays many vital roles:

Along with saturated fats, cholesterol in the cell membrane gives our cells necessary stiffness and stability. When the diet contains an excess of polyunsaturated fatty acids, these replace saturated fatty acids in the cell membrane, so that the cell walls actually become flabby. When this happens, cholesterol from the blood is "driven" into the tissues to give them structural integrity. This is why serum cholesterol levels may go down temporarily when we replace saturated fats with polyunsaturated oils in the diet.

Cholesterol acts as a precursor to vital corticosteroids, hormones that help us deal with stress and protect the body against heart disease and cancer; and to the sex hormones like androgen, testosterone, estrogen and progesterone.

Cholesterol is a precursor to vitamin D, a very important fat-soluble vitamin needed for healthy bones and nervous system, proper growth, mineral metabolism, muscle tone, insulin production, reproduction and immune system function.

The bile salts are made from cholesterol. Bile is vital for digestion and assimilation of fats in the diet.

Recent research shows that cholesterol acts as an antioxidant. This is the likely explanation for the fact that cholesterol levels go up with age. As an antioxidant, cholesterol protects us against free radical damage that leads to heart disease and cancer.

Cholesterol is needed for proper function of serotonin receptors in the brain. Serotonin is the body's natural "feel-good" chemical. Low cholesterol levels have been linked to aggressive and violent behavior, depression and suicidal tendencies.

Mother's milk is especially rich in cholesterol and contains a special enzyme that helps the baby utilize this nutrient. Babies and children need cholesterol-rich foods throughout their growing years to ensure proper development of the brain and nervous system.

Dietary cholesterol plays an important role in maintaining the health of the intestinal wall. This is why low-cholesterol vegetarian diets can lead to leaky gut syndrome and other intestinal disorders.
Cholesterol is not the cause of heart disease but rather a potent antioxidant weapon against free radicals in the blood, and a repair substance that helps heal arterial damage (although the arterial plaques themselves contain very little cholesterol.) However, like fats, cholesterol may be damaged by exposure to heat and oxygen. This damaged or oxidized cholesterol seems to promote both injury to the arterial cells as well as a pathological buildup of plaque in the arteries. Damaged cholesterol is found in powdered eggs, in powdered milk (added to reduced-fat milks to give them body) and in meats and fats that have been heated to high temperatures in frying and other high-temperature processes.

High serum cholesterol levels often indicate that the body needs cholesterol to protect itself from high levels of altered, free-radical-containing fats. Just as a large police force is needed in a locality where crime occurs frequently, so cholesterol is needed in a poorly nourished body to protect the individual from a tendency to heart disease and cancer. Blaming coronary heart disease on cholesterol is like blaming the police for murder and theft in a high crime area.

Poor thyroid function (hypothyroidism) will often result in high cholesterol levels. When thyroid function is poor, usually due to a diet high in sugar and low in usable iodine, fat-soluble vitamins and other nutrients, the body floods the blood with cholesterol as an adaptive and protective mechanism, providing a superabundance of materials needed to heal tissues and produce protective steroids. Hypothyroid individuals are particularly susceptible to infections, heart disease and cancer.

The cause of heart disease is not animal fats and cholesterol but rather a number of factors inherent in modern diets, including excess consumption of vegetables oils and hydrogenated fats; excess consumption of refined carbohydrates in the form of sugar and white flour; mineral deficiencies, particularly low levels of protective magnesium and iodine; deficiencies of vitamins, particularly of vitamin C, needed for the integrity of the blood vessel walls, and of antioxidants like selenium and vitamin E, which protect us from free radicals; and, finally, the disappearance of antimicrobial fats from the food supply, namely, animal fats and tropical oils. These once protected us against the kinds of viruses and bacteria that have been associated with the onset of pathogenic plaque leading to heart disease.

While serum cholesterol levels provide an inaccurate indication of future heart disease, a high level of a substance called homocysteine in the blood has been positively correlated with pathological buildup of plaque in the arteries and the tendency to form clots-a deadly combination. Folic acid, vitamin B6, vitamin B12 and choline are nutrients that lower serum homocysteine levels.53 These nutrients are found mostly in animal foods.

The best way to treat heart disease, then, is not to focus on lowering cholesterol-either by drugs or diet-but to consume a diet that provides animal foods rich in vitamins B6 and B12; to bolster thyroid function by daily use of natural sea salt, a good source of usable iodine; to avoid vitamin and mineral deficiencies that make the artery walls more prone to ruptures and the buildup of plaque; to include the antimicrobial fats in the diet; and to eliminate processed foods containing refined carbohydrates, oxidized cholesterol and free-radical-containing vegetable oils that cause the body to need constant repair.

Probiotics may ease gut disorders


Probiotics may help ease gut disorders linked to long-term stress such as Crohn's disease, research suggests.
A team at Canada's McMaster University analysed gut tissue taken from rats put in stressful situations.

Animals fed drinking water containing probiotic bacteria showed less signs that harmful bugs were mobilising to cause damage.

The gut study suggests probiotic bacteria literally crowd out their harmful peers.

As we cannot always remove stress, it would be helpful if we could find new ways to ameliorate its effects.

Chronic stress is known to be implicated in the development of irritable bowel syndrome and in the worsening of symptoms of inflammatory bowel disease, such as Crohn's and ulcerative colitis.
It also sensitises the gut, producing allergies to certain foodstuffs.

The researchers designed their experiements to try to produce psychological stress in rats similar to that seen in humans. This was done by placing the animals on small platforms surrounded by water.

Half the rats were fed drinking water containing probiotic bacteria in the form of Lactobacillus helveticus and Lactobacillus rhamnosus for a period of seven days before and during the stress sessions.

Analysis showed that exposure to stress made the animals' guts 'leaky', and increased the amount of potentially harmful bacteria sticking to the cells lining the gut wall.

Harmful bacteria were also detected in the mesenteric lymph nodes, which drain fluid coming from the intestine, indicating that bacteria had entered the body and activated the immune system.

However, probiotic treatment minimised the changes in chemical signalling and prevented bacterial 'stickiness' and movement to the mesenteric lymph nodes.

The researchers believe that probiotics probably compete for space with harmful bacteria, helping to dampen down inflammatory responses.

They say their use offers a potentially promising approach to the management of intestinal problems caused by stress.

Professor Alastair Forbes, medical director of the digestive health charity Core and an expert in gastroenterology at University College Hospital, London, said the study presented a "reasonable hypothesis".

He warned research on rats was a long way from finding a similar effect in humans.

But he said previous work had shown that people who drank probiotics did not have a significantly raised total level of bacteria - suggesting there might be some truth in the theory that good and harmful bacteria might compete for space.

However, he said it was possible that probiotics also exerted some sort of biochemical effect on other bacteria.

"As we cannot always remove stress, it would be helpful if we could find new ways to ameliorate its effects," he said.

"I wanted tomato soup so bad this winter I finally figured out how to make it in the microwave really fast without starch. Take some V-8 vegetable juice, and pour it into a bowl. Add a little olive oil, some ground up almond meal, about a tablespoon or two, some curry and basil. [..snip..] Microwave, stir, ready. Vegetables may be added, cucumber is good. It looks a little weird but it has the right taste and smells wonderful. Now that I have my substitute, with the real olive oil, the canned stuff looks rather pathetic.

Can do the same thing with fresh bottled carrot juice, or carrot mixed with pumpkin puree, omit basil, add ginger, maybe some coconut milk, and top with more chopped nuts. Mmmm. "
