1. Fish Oil. It's no secret that omega-3's are one of your most
potent inflammation fighters and studies have shown this to be true in the case
of tnf as well. In one study of healthy volunteers, tnf-alpha synthesis was
dramatically reduced by 74% as fish oil dosage was increased to about 9 grams
per day.  NOTE: This is a hefty dose and higher than what is normally
recommended for typical fish oil supplementation. Going with a smaller dosage
should result in significant reductions according to this study.
2. CoQ10. A number of studies have shown that this antioxidant
molecule reduces tnf levels.
3. Mediterranean Diet. One study the degree of adherence to a
Mediterranean Diet was inversely related to TNF-alpha levels.  In other
words, the more the Mediterranean Diet, the less the tnf.
4. Turmeric / Curcumin. Many studies have shown that this spice,
present in yellow mustard and curry, inhibits TNF production. 
5. Green Tea / EGCG. EGCG is one of the most potent of all plant
phytochemicals and has a host of miraculous properties. Multiple studies show
that EGCG limits TNF-alpha production. 
6. Vitamin E / Alpha Tocopherol. This vitamin not only limits TNF
release in arteries but also prevents oxidation of LDL and many other processes
that lead to arteriosclerosis.  Although scientists have studies alpha
tocopherol, it is probably prudent to only take mixed tocopherol Vitamin E
because the alpha form can lower levels of the others (gamma, etc.).
7. Ashwagandha. This traditional ayurvedic herb has been shown to
reduce TNF-alpha output.
8. Magnesium. There is strong evidence that low magnesium levels can
negatively affect TNF levels.  Of course, one can easily get enough magnesium
from a well-rounded, plant-based diet, but still many in modern societies do
10. Tart Cherry Juice. This cherry juice is, well, tart, but is well
worth the effort as it tightly clamps down on rising TNF alpha levels. It is so
powerful at controlling inflammation that is can reduce post-exercise muscle
soreness and is used by many athletes already.
11. Progressive Muscle Relaxation (PMR). One of the most powerful
ways to control TNF alpha levels is actually not a food, juice or supplement but
rather a time-proven relaxation technique. PMR was developed originally as
psychological tool but has since proven itself to help with many health-related
NOTE: TNF alpha is not the only cytokine that needs to be
controlled. In addition, many foods and a number
of supplements favorably alter the upstream TNF inflammatory signaling.. Alpha
lipoic acid and an extract of Korean Ginseng are
examples of this.   It should be noted, though, that other extract
of Ginseng have actually stimulated TNF-alpha itself.  Quercetin, the
miracle phytochemical in apples and onions, is also in this category.
CAUTION: The only potentially negative affect of cocoa that I know is
that it does seem to stimulate TNF-alpha.  The same thing has been found in
certain Korean Ginseng extracts as well.
