Amyloid is a fibril protein with several additional molecules. Presently, 25 proteins have been reported as main fibril components. Many fibril proteins appear as fragments of larger precursors and for some types it is not clear whether fragmentation comes before or after fibrillation. The self-assembly by amyloid proteins can be speeded up by seeding with preformed fibrils. See Alzheimer's disease for information on natural ways to treat or prevent this condition. Beta-amyloid also causes nerve cell damage in the eye from blindness-inducing glaucoma.

Amyloid, diet and nutrition
It is my opinion that amyloid formation can be influenced by diet and the types of foods we eat. A healthy diet with many fresh vegetables and herbs - which contain many flavonoids - is less likely to lead to formation than a high sugar high trans fat diet. Eating cold water wish with lots of omega-3 fatty acids could also be helpful.

Common compounds in the Western diet seem to promote Alzheimer's-linked brain deposits and memory problems in mice. Scientists found that when they added the compounds -- called advanced glycation end products (AGEs) -- to the lifelong diets of laboratory mice, the animals developed greater amounts of beta-amyloid in the brain. Beta-amyloid is the protein that makes up the brain "plaques" seen in people with Alzheimer's disease. What's more, mice fed these compounds developed more problems with movement and memory as they aged compared to mice that spent their lives dining on chow that produced low levels of these chemicals. AGEs are naturally present in small amounts in the human body, said senior researcher Dr. Helen Vlassara, of the Mount Sinai School of Medicine in New York City. But you also ingest the compounds through food -- particularly animal products prepared at a high heat.That includes fried, grilled or broiled meats, and dairy products that are pasteurized or sterilized.

Natural Herbs and amyloid plaque prevention
Many herbal and dietary compounds and flavonoids probably block amyloid formation. Here are some examples and if you visit the articles there are links where you can purchase some of the products:

Acetyl l-carnitine is an antioxidant and brain enhancement nutrient.

Benfotiamine has been beneficial in a rodent study.
   Powerful beneficial effects of benfotiamine on cognitive impairment and beta-amyloid deposition in amyloid precursor protein/presenilin-1 transgenic mice.
   Brain. 2010; Department of Neurology, State Key Laboratory of Medical Neurobiology, Fudan University, Shanghai, China.
   Thiamine (vitamin B1)-dependent processes are critical in glucose metabolism and have been found to be impaired in brains from patients with Alzheimer's disease. However, thiamine treatment exerts little beneficial effect in these patients. Here, we tested the effect of benfotiamine, a thiamine derivative with better bioavailability than thiamine, on cognitive impairment and pathology alterations in a mouse model of Alzheimer's disease, the amyloid precursor protein/presenilin-1 transgenic mouse. We show that after a chronic 8 week treatment, benfotiamine dose-dependently enhanced the spatial memory of amyloid precursor protein/presenilin-1 mice in the Morris water maze test. Furthermore, it effectively reduced both amyloid plaque numbers and phosphorylated tau levels in cortical areas of the transgenic mice brains. Unexpectedly, these effects were not mimicked by another lipophilic thiamine derivative, fursultiamine, although both benfotiamine and fursultiamine were effective in increasing the levels of free thiamine in the brain. In the animal Alzheimer's disease model, benfotiamine appears to improve the cognitive function and reduce amyloid deposition via thiamine-independent mechanisms, which are likely to include the suppression of glycogen synthase kinase-3 activities.

Carnosine is a potent antixodiant and could be of benefit in reducing amyloid formation.

CoQ10, or coenzyme Q10, may be of benefit.

Curcumin, an extract from turmeric, may be helpful.

Fish oils, including EPA and DHA omega-3 fatty acids should be considered.

Hypericum perforatum, known as St. John's wort. In a microglial cell line pretreated with St. John's wort extract, the cell death evoked by treatment with amyloid-beta was attenuated significantly in a dose-dependent manner.

Myricetin inhibits beta-amyloid fibril formation, a key problem with Alzheimer's disease.

Uncaria rhynchophylla could be of benefit.

Amyloid disease
This disease is due to the deposition of amyloid in organs and tissues. Amyloid disease variants share common mechanisms which lead to protein fibril formation and deposition. Primary amyloidosis, while the most common form of amyloidosis, is a sporadic disease. Secondary (reactive) amyloidosis occurs in those with chronic inflammatory disease or cancer. Alzheimer disease, while very common in the aged population, is unpredictable except for those rare forms of familial Alzheimer disease with characterized mutations in specific genes.

Beta amyloid protein
The principal component of amyloid is the beta-amyloid protein (A beta), a 39-43 amino acid peptide composed of a portion of the transmembrane domain and the extracellular domain of the amyloid precursor protein.

Amyloid eprodisate treatment
Treatment with eprodisate can slow the decline in renal function that usually occurs with amyloid A (AA) amyloidosis involving the kidneys. Eprodisate belongs to a new class of drugs that blocks amyloid build-up in various tissues by inhibiting the interactions of amyloidogenic proteins and glycosaminoglycans. The Eprodisate for amyloid A Amyloidosis Trial (EFAAT) involved 183 patients who were randomized to receive eprodisate or placebo for 24 months. The main outcome measure was disease worsening, defined as a doubling of serum creatinine levels, a fall in creatinine clearance by 50% or more, progression to end-stage kidney disease, or death. At 24 months, disease worsening was noted in 40% of control patients compared with 27% of those given eprodisate. Treatment with eprodisate was generally well tolerated with no increase in adverse events relative to placebo. Eprodisate works by directly targeting AA amyloid formation. EFAAT was funded, in part, by drugmaker Neurochem, which is planning to market eprodisate as Kiacta. N Engl J Med 2007.
