Omega 3 Fish Oils
Recent work reports that the omega-3 fatty acid docosahexaenoic acid (DHA) found in fish oil increases the production of LR11, a protein that is found at reduced levels in Alzheimer's patients and which is known to destroy the protein that forms the "plaques" associated with the disease.
Does it work?
- Recent work reports that the omega-3 fatty acid docosahexaenoic acid (DHA) found in fish oil increases the production of LR11, a protein that is found at reduced levels in Alzheimer's patients and which is known to destroy the protein that forms the "plaques" associated with the disease.
- There is strong scientific evidence from human trials that omega-3 fatty acids from fish or fish oil supplements (EPA + DHA) significantly reduce blood triglyceride levels. Benefits appear to be dose-dependent. Fish oil supplements also appear to cause small improvements in high-density lipoprotein ("good cholesterol"); however, increases (worsening) in low-density lipoprotein levels (LDL/"bad cholesterol") are also observed.
- While far from robust, there is enough epidemiological, laboratory and clinical evidence to suggest that omega-3 fatty acids may play a role in certain cases of depression. Fish oil supplements are well tolerated, and have been shown to be without significant side effects over large scale, 3-year research. Generally, omega-3 supplements are inexpensive, which makes them an attractive option as an adjuvant to standard care.
- Multiple human trials report small reductions in blood pressure with intake of omega-3 fatty acids. DHA, or docosahexaenoic acid, may have greater benefits than EPA, or eicosapentaenoic acid. There is strong scientific evidence from human trials that omega-3 fatty acids from fish or fish oil supplements significantly reduce cholesterol levels, which may also help patients with hypertension.
Dangers and possible side effects:
- Avoid if allergic or hypersensitive to fish, omega-3 fatty acid products that come from fish, nuts, or linolenic acid or omega-3 fatty acid products that come from nuts.
- Avoid during active bleeding. Use cautiously with bleeding disorders, diabetes, low blood pressure or drugs, herbs or supplements that treat any such conditions. Use cautiously before surgery.
- Recommended that intake be limited in pregnant/nursing women to a single 6-ounce meal per week, and in young children to less than 2 ounces per week.
