PSA stands for prostate-specific antigen and is a protein produced by prostate cells. A PSA test measures the levels of PSA in the blood and is used primarily to screen for prostate cancer. Flaxseeds are obtained from the flax plant and, according to the University of Maryland Medical Center, may be beneficial for certain health conditions, such as high cholesterol, menopausal symptoms, heart disease and cancer. Flaxseeds may help lower PSA levels in the body. Consult a health-care professional before taking flaxseeds.
Flaxseeds
Flaxseeds are a source of fiber and a material called mucilage. These substances expand in water, increasing the bulk of the stool and enabling it to pass quickly through the gastrointestinal tract, which helps relieve symptoms of constipation. Flaxseeds are also a source of protein and the omega-3 essential fatty acid alpha-linolenic acid.
PSA Test
Healthy men have a low level of PSA in their blood. Prostate cancer can cause high PSA levels. However, other non-cancerous health conditions, such as an enlarged or inflamed prostate, can also increase your PSA levels. The PSA test is only one tool used to screen for prostate cancer. A digital rectal exam, when your doctor inserts a gloved finger into your rectum to feel if the prostate has any unusual lumps or hard areas may also be carried out. If you have a high PSA test reading and abnormal results from your digital rectal exam, a prostate biopsy may be carried out. A diagnosis of cancer is based on the biopsy results.
Flaxseeds and PSA Readings
In a study published in a May 2004 issue of "Urology," researchers studied the effect of flaxseeds on prostate cancer. The authors also looked at the effects of flaxseeds on circulating levels of PSA, testosterone and cholesterol. The study involved 15 men who were scheduled to have a repeat prostate biopsy and were following a low-fat diet and taking 30 g flaxseed daily for six months. The team found that flaxseeds did not cause PSA readings to be high but had the opposite effect, causing a significant decrease in PSA levels. The authors also found that flaxseeds decreased cholesterol levels but had no effect on testosterone levels.
Considerations
According to the University of Maryland Medical Center, flaxseed may delay the absorption of medications and nutrients and should be taken several hours before or after your medications and supplements. If you suffer from prostate problems, diabetes, breast cancer or schizophrenia, consult a doctor before taking flaxseeds.
