HEALING A LEAKY GUT © What Doctors Don't Tell You (Volume 8, Issue 5) It's possible to cure a leaky gut with a nutrient dense diet and appropriate supplements. Many natural substances help repair the intestinal mucosal surface or support the liver when stressed by toxins. Your vitamin and mineral supplements should include all the B vitamins, vitamin A, C and E, zinc, selenium, molybdenum, manganese, and magnesium. Because of the association between increased gut permeability and pancreatic dysfunction, pancreatic enzymes may also be needed.Avoid drugs which damage the gut. Test for and get treated intestinal infection or dysfunction. If you haven't discovered all your allergies, follow a highly nutritious elimination diet, tailor made for you. The following substances can repair the gut wall: Epidermal growth factor (EGF), a polypeptide that stimulates growth and repair of epithelial tissue, is widely distributed in the body, with high concentrations detectable in saliva. Chew your food thoroughly, to increase salivary EGF. Also, purified EGF has been shown to heal ulceration of the small intestine (Lancet, 1993; 341: 843-8). Saccharomyces boulardii, a non pathogenic yeast originally isolated from the surface of lichee nuts, has been widely used in Europe to treat diarrhea. In France it is popularly called "Yeast against yeast" and is thought to help clear the skin in addition to the gut. Clinical trials have demonstrated the effectiveness of Saccharomyces boulardii in the treatment or prevention of diarrhea (Am J Gastroenterol, 1989; 84: 1285-7; Gastroenterol, 1989; 96; 981-8). Lactobacillus caseii var GG, a strain of lactobacillus isolated and purified in Finland, has been shown effective in the prevention of diarrhea and in the treatment of colitis. It also improves the gut permeability associated with rotavirus infection (Ann Med, 1990; 22: 57-9). Although the ability of other lactobacillus preparations to improve leaky gut has not been directly tested, it is suggested by the ability of live cultures of L acidophilus to diminish radiation induced diarrhea, a condition directly produced by the loss of mucosal integrity. Glutamine, the amino acid needed for the maintenance of intestinal metabolism, structure and function, has been shown to reverse all the gut abnormalities in patients fed intravenously. Glutamine also repairs gut lining damage caused by chemotherapy or radiation (Arch Surg, 1990; 125: 1040-5). Glutathione (GSH) is an important antioxidant. Lowered levels of liver glutathione is a common occurrence in leaky gut syndromes, contributing to liver dysfunction and liver necrosis among alcoholics and immune impairment in patients with AIDS. The most effective way to raise liver glutathione is to take its dietary precursors, systeine or methionine; the best supplements for leaky gut are GSH and N-acetyl cysteine. Avoid taking during treatment of parasite infection, especially with Artemisia. Take flavonoids before eating. They may block allergic reactions which increase permeability. Catechins have been used in Europe to treat gastric ulcerations; the flavonoids in milk thistle (silymarin) and in dandelion root (taraxacum) can protect the liver. Take essential fatty acids (EFAs), particularly gammalinolenic acid (GLA). In laboratory experiments, fish oil was able to prevent intestinal mucosal injury produced by methotrexate and protect the body from the toxins produced in the gut (Am J Clin Nutr, 1991; 54: 346-50). Take these in their most concentrated and physiologically active form to avoid exposure to large quantities of polyunsaturated fatty acids. If you are supplementing with dietary fibre, make sure you are taking hypoallergenic insoluble fibre and watch the amount. Too much may increase gut permeability (J Nutr, 1983; 113: 2300-7). Gamma oryzanol, derived from rice bran, has been extensively researched in Japan for its healing effects in the treatment of gastric and duodenal ulcers and potent antioxidant activity (Rep Hokaido Inst Pub Health, 1966; 16: 111).

HealthAtoZ.com: Keratosis Pilaris Keratosis Pilaris: Causes and Symptoms "The specific causes of this disorder are unknown. Since this disorder runs in families, it is thought to be hereditary. Keratosis pilaris is not a serious disorder and is not contagious. The symptoms of keratosis pilaris are based on the development of small white papules the size of a grain of sand on the upper arms, thighs, and occasionally the buttocks and face. The papules occur around a hair follicle and are firm and white. They feel a little like coarse sandpaper, but they are not painful and there usually is no itching associated with them.

ILT: Essential Fatty Acids (EFAs) Depression "When researchers monitor eating habits across countries, they find that as fish consumption goes up, depression rates go down. In fact, there is a sixty-fold difference in depression rates across countries from the highest (Japan and Taiwan) to the lowest (North America, Europe and New Zealand) omega-3 fat consumption. Even postpartum depression decreases as women increase their consumption of fish. Many people also report a drop in mood when they switch too quickly to a low-fat diet.

Logan, ND, FRSH Correcting an Omega-3 Deficiency Note: More information about sources of omega-3s can be found on the page Nutrition: Essential Fatty Acid (EFA) Sources Flax "Flax, our richest source of omega 3, quickly replenishes a long-standing omega 3 deficiency. A dozen 8 oz. bottles of good quality flax oil consumed over the course of a few months will suffice [approximately one bottle every five days, 1.6 ounces per day]." The Edelson Center: Essential Fatty Acids: The Healing Fats "There have been some published case reports indicating that flaxseed oil may be helpful in cases of bipolar depression and the anxiety disorder agoraphobia.40 The first controlled clinical trial indicating that omega-3 fatty acids may be of benefit in depression was published in 1999. In this case, 9:6 g ['9:6 g' should be read a dose of 6 g per day for a period of nine days?] of EPA/DHA versus placebo led to longer periods of remission and improvement in depressive symptoms in those with bipolar depression.41" New Findings About Omega-3 Fatty Acids and Depression by Alan C. Logan, ND, FRSH 2g Daily of Pure EPA "Some researchers theorize that such high doses of EPA/DHA may not be necessary and that low levels of pure EPA may be of benefit.32 In a study published in the American Journal of Psychiatry, researchers showed that just 2g of pure EPA could improve the symptoms of treatment-resistant depression. The researchers found that the EPA (versus placebo), when added to an ineffective antidepressant for one month, significantly improved depressive symptoms.42" New Findings About Omega-3 Fatty Acids and Depression by Alan C. Logan, ND, FRSH 1g Daily of Pure EPA "A larger study published in Archives of General Psychiatry replicated these findings, however, this time various doses of EPA were examined. Those on ineffective antidepressants were given 1g, 2g or 4g of pure EPA or a placebo in addition to the medication. Interestingly, the 1g daily dose of EPA led to the most significant improvements over the three-month study; it appeared that less was more. There were significant improvements in depressive symptoms, sleep, anxiety, lassitude, libido and thoughts of suicide.43" New Findings About Omega-3 Fatty Acids and Depression by Alan C. Logan, ND, FRSH "Harvard researchers have also shown that just 1g of pure EPA is beneficial in the treatment of borderline personality disorder. This personality disorder, which is particularly difficult to treat, is characterized by both depressive and aggressive symptoms. This was a two-month placebo-controlled study and the results showed that EPA has a mood-regulating effect, improving both depression and aggression versus placebo.46" New Findings About Omega-3 Fatty Acids and Depression by Alan C. Logan, ND, FRSH 4.4g EPA and 2.2g DHA Mix "Researchers from Taiwan Medical University published a recent study in which they found that a 4.4g EPA and 2.2g DHA mix could alleviate depression versus placebo in those with treatment-resistant depression. This was a two-month study involving patients who were on antidepressants that were not working. As with the other omega-3 studies discussed, the fish oil was well tolerated and no adverse events were reported.44" New Findings About Omega-3 Fatty Acids and Depression by Alan C. Logan, ND, FRSH Antarctic Krill Oil (400mg EPA, 240mg DHA) "There is also evidence that omega-3 oils may be of benefit in treating depressive symptoms outside of major depressive disorder. Canadian researchers showed that Antarctic krill oil (400mg EPA, 240mg DHA) could improve depressive symptoms associated with premenstrual syndrome.45" New Findings About Omega-3 Fatty Acids and Depression by Alan C. Logan, ND, FRSH DHA Alone not Recommended "To date, with one exception, all studies conducted on omega-3 fatty acids and mood have had a positive outcome. The singular negative study examined pure DHA in patients with depression. The results in the case showed that DHA alone was no better than placebo in alleviating depressive symptoms.47" New Findings About Omega-3 Fatty Acids and Depression by Alan C. Logan, ND, FRSH Omega-6 Deficiency "Long--term exclusion or excessive use of flax oil can result in omega 6 deficiency after about two years, because flax oil is omega 3 rich but omega 6 poor."

Logan, ND, FRSH Correcting an Omega-3 Deficiency Note: More information about sources of omega-3s can be found on the page Nutrition: Essential Fatty Acid (EFA) Sources Flax "Flax, our richest source of omega 3, quickly replenishes a long-standing omega 3 deficiency. A dozen 8 oz. bottles of good quality flax oil consumed over the course of a few months will suffice [approximately one bottle every five days, 1.6 ounces per day]." The Edelson Center: Essential Fatty Acids: The Healing Fats "There have been some published case reports indicating that flaxseed oil may be helpful in cases of bipolar depression and the anxiety disorder agoraphobia.40 The first controlled clinical trial indicating that omega-3 fatty acids may be of benefit in depression was published in 1999. In this case, 9:6 g ['9:6 g' should be read a dose of 6 g per day for a period of nine days?] of EPA/DHA versus placebo led to longer periods of remission and improvement in depressive symptoms in those with bipolar depression.41" New Findings About Omega-3 Fatty Acids and Depression by Alan C. Logan, ND, FRSH 2g Daily of Pure EPA "Some researchers theorize that such high doses of EPA/DHA may not be necessary and that low levels of pure EPA may be of benefit.32 In a study published in the American Journal of Psychiatry, researchers showed that just 2g of pure EPA could improve the symptoms of treatment-resistant depression. The researchers found that the EPA (versus placebo), when added to an ineffective antidepressant for one month, significantly improved depressive symptoms.42" New Findings About Omega-3 Fatty Acids and Depression by Alan C. Logan, ND, FRSH 1g Daily of Pure EPA "A larger study published in Archives of General Psychiatry replicated these findings, however, this time various doses of EPA were examined. Those on ineffective antidepressants were given 1g, 2g or 4g of pure EPA or a placebo in addition to the medication. Interestingly, the 1g daily dose of EPA led to the most significant improvements over the three-month study; it appeared that less was more. There were significant improvements in depressive symptoms, sleep, anxiety, lassitude, libido and thoughts of suicide.43" New Findings About Omega-3 Fatty Acids and Depression by Alan C. Logan, ND, FRSH "Harvard researchers have also shown that just 1g of pure EPA is beneficial in the treatment of borderline personality disorder. This personality disorder, which is particularly difficult to treat, is characterized by both depressive and aggressive symptoms. This was a two-month placebo-controlled study and the results showed that EPA has a mood-regulating effect, improving both depression and aggression versus placebo.46" New Findings About Omega-3 Fatty Acids and Depression by Alan C. Logan, ND, FRSH 4.4g EPA and 2.2g DHA Mix "Researchers from Taiwan Medical University published a recent study in which they found that a 4.4g EPA and 2.2g DHA mix could alleviate depression versus placebo in those with treatment-resistant depression. This was a two-month study involving patients who were on antidepressants that were not working. As with the other omega-3 studies discussed, the fish oil was well tolerated and no adverse events were reported.44" New Findings About Omega-3 Fatty Acids and Depression by Alan C. Logan, ND, FRSH Antarctic Krill Oil (400mg EPA, 240mg DHA) "There is also evidence that omega-3 oils may be of benefit in treating depressive symptoms outside of major depressive disorder. Canadian researchers showed that Antarctic krill oil (400mg EPA, 240mg DHA) could improve depressive symptoms associated with premenstrual syndrome.45" New Findings About Omega-3 Fatty Acids and Depression by Alan C. Logan, ND, FRSH DHA Alone not Recommended "To date, with one exception, all studies conducted on omega-3 fatty acids and mood have had a positive outcome. The singular negative study examined pure DHA in patients with depression. The results in the case showed that DHA alone was no better than placebo in alleviating depressive symptoms.47" New Findings About Omega-3 Fatty Acids and Depression by Alan C. Logan, ND, FRSH Omega-6 Deficiency "Long--term exclusion or excessive use of flax oil can result in omega 6 deficiency after about two years, because flax oil is omega 3 rich but omega 6 poor."
