People are being snowed by the idea that a "balanced diet", whatever that is, can provide all the nutrition one needs. That idea is demonstrably false, but when was the last time your doctor tested your folate level?

> BACKGROUND: A consistent finding in major depression has been a low plasma and red cell folate which has also been linked to poor response to antidepressants. The present investigation was designed to investigate whether the co-administration of folic acid would enhance the antidepressant action of fluoxetine. METHODS: 127 patients were randomly assigned to receive either 500 microg folic acid or an identical looking placebo in addition to 20 mg fluoxetine daily. All patients met the DSM-III-R criteria for major depression and had a baseline Hamilton Rating Scale (17 item version) score for depression of 20 or more. Baseline and 10-week estimations of plasma folate and homocysteine were carried out. RESULTS: Patients receiving folate showed a significant increase in plasma folate.This was less in men than in women. Plasma homocysteine was significantly decreased in women by 20.6%, but there was no significant change in men. Overall there was a significantly greater improvement in the fluoxetine plus folic acid group. This was confined to women where the mean Hamilton Rating Scale score on completion was 6.8 (S.D. 4. 1) in the fluoxetine plus folate group, as compared to 11.7 (S.D. 6. 7) in the fluoxetine plus placebo group (P<0.001).A percentage of 93. 9 of women, who received the folic acid supplement, showed a good response (>50% reduction in score) as compared to 61.1% of women who received placebo supplement (P<0.005). Eight (12.9%) patients in the fluoxetine plus folic acid group reported symptoms possibly or probably related to medication, whereas in the fluoxetine plus placebo group 19 (29.7%) patients reported such symptoms (P<0.05). LIMITATIONS AND CONCLUSIONS: Folic acid is a simple method of greatly improving the antidepressant action of fluoxetine and probably other antidepressants. Folic acid should be given in doses sufficient to decrease plasma homocysteine. Men require a higher dose of folic acid to achieve this than women, but more work is required to ascertain the optimum dose of folic acid.

> OBJECTIVE: In the present study, we assessed the relationship between serum folate, vitamin B12, and homocysteine levels and clinical response in patients with major depressive disorder (MDD) who had previously failed to respond to open treatment with fluoxetine 20 mg/day and were enrolled in a 4-week, double-blind trial of either (1) fluoxetine dose increase, (2) lithium augmentation of fluoxetine, or (3) desipramine augmentation of fluoxetine. METHOD: Fifty-five outpatients (mean +/- SD age = 41.7 +/- 10.6 years; 50.9% women) with MDD as assessed with the Structured Clinical Interview for DSM-III-R who were enrolled in the double-blind trial had serum folate, vitamin B12, and homocysteine measurements completed at baseline (prior to fluoxetine treatment initiation). Folate levels were classified as either low (< or = 2.5 ng/mL) or normal. Vitamin B12 levels were classified as either low (< or = 200 pg/mL) or normal. Homocysteine levels were classified as either elevated (> or = 13.2 micromol/L) or normal. With the use of a logistic regression, we then assessed the relationship between (1) low or normal folate levels, (2) normal or low B12 levels, and (3) elevated or normal homocysteine levels and clinical response to double-blind treatment. The study was conducted from November 1992 to January 1999. RESULTS: Low serum folate levels (chi2=3.626, p =.04), but not elevated homocysteine (p >.05) or low vitamin B12 levels (p >.05), were associated with poorer response to treatment. The response rates for patients with (N = 14) and without (N = 38) low folate levels were 7.1% versus 44.7%, respectively. CONCLUSION: Low serum folate levels were found to be associated with further treatment resistance among patients with fluoxetine-resistant MDD.

Homocysteine levels were classified as either elevated (> or = 13.2 micromol/L) or normal. With the use of separate logistic regressions, we then assessed the relationship between folate, vitamin B12, and homocysteine level status and relapse. The study was conducted from November 1992 to January 1999. RESULTS: The presence of low serum folate levels (p =.004), but not low B12 (p >.05) or elevated homocysteine levels (p >.05), was associated with relapse during continuation treatment with fluoxetine.

Larry,
Very interesting articles, thanks for posting. What becomes a bit problematic for me is obtaining a real determination of my nutritional status. I wonder if a basic blood test measures levels of folate and/or homocysteine. Below is another article on folate and depression.
JakeDepression, Low Folate Levels Linked
Tufts nutrition experts find that the vitamin folate – found in a variety of foods including vegetables and cereals – may help ease depression and prevent memory loss.
Boston [06-23-03] The food you eat may impact more than just your physical health – it could also play a role in your mental health as well. According to recent studies by Tufts nutrition experts, low levels of the vitamin folate – found in a variety of foods – has been linked with depression, low energy levels and even memory loss.
“[Tufts’ Martha Morris and four colleagues] found that those who had experienced major depression had lower concentrations of folate in their bloodstream and red blood cells than those who had never been depressed,” reported the Hartford Courant. “In addition, those with chronic low-level depression - also known as dysthymia - had lower red blood cell levels than the non-depressed.”
The research team, which conducted their research at Tufts’ Jean Mayer USDA Human Nutrition Research Center on Aging, studied data on nearly 3,000 people ages 15 to 39.
“Supplementation possibly helps by reducing fatigue and improving energy levels,” Morris, an epidemiologist who teaches at Tufts’ Gerald J. and Dorothy R. Friedman School of Nutrition Science and Policy, told the newspaper. “People who are diagnosed with depression should then find out whether they are folate deficient to determine if a supplement is warranted.”
Morris’ research opens the door for future research to pinpoint exactly why vitamin deficiencies result in different types of medical conditions.
“Clinical studies show that folate supplementation helps depressed people, although we still don’t have a good idea why depressed people have low folate status,” Morris said.
This isn’t the first time that Tufts researchers have further shown the health benefits of folate. In 2001, Morris and her colleagues found that folate helps significantly modify homocysteine levels in the brain. The presence of homocysteine has been associated with cognitive impairment and has been linked to the onset of Alzheimer disease, dementia and strokes. And, Dr. Irwin Rosenberg, dean of the Friedman School of Nutrition Science and Policy, was among the very first worldwide to explore the relationship between folate, homocysteine and cardiovascular disease resulting in landmark publications.
“Researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University were looking for a relationship between blood homocysteine levels and memory loss,” reported the Agriculture Research Service. “Their research had established that homocysteine levels were higher in elderly people with low intakes of B vitamins, especially folate.”
Despite its benefits, Morris and her colleagues caution that people shouldn’t make a significant increase in their folate intake without consulting a doctor.
“While studies on folate and antidepressant treatment are promising, scientists do not yet know which patients should get folate supplements, in what dose or for how long,” reported the Courant. “Furthermore, the safety of high-dosage supplementation has not been established.”
Good sources for folate include vegetables and fruits such as leafy greens, strawberries, and melons, as well as dried beans and cereals, or any multivitamin.
