For a 40/40/20 diet, I have a little more room for red meat that way too.

I like to mix things up; I take 3-6 fish oil caps and maybe 2-3 borage oil, or maybe 1T of flax other days. I mix flax oil w/ natty PB too. I doubt that I don't get enough of the "good" fats given this regimen. I think one of the concerns with huge amounts of daily fish oil is the cumulative overdosing of vitamin D, which is present in the fish oil and not water soluble. Therefore you can't just piss it out, as you would with others like vitamin C, etc.

Flax Seed Benefits vs. Fish Oil Benefits
Flax seed oil benefits are numerous, and as such flax seed has been recommended in recent years as an essential part of a healthy diet. However, new evidence has emerged that although flaxseed is important, fish oil might be an even better source of Omega-3 fatty acids.
What are flax seed oil benefits and how can it help you?
Flax seed, also known as linseed, is an ancient crop that has been harvested all over the world. Its therapeutic properties have long been touted, as ancient peoples used it to soothe abdominal pains and aid digestion.
Flax seed oil contains Omega-3 fatty acids, which have incredible immunity boosting qualities, meaning they can help your body fight off illness and disease. They also contain anti-inflammatory properties which may help manage depression, cancer and even slow the aging process.
Most people are Omega-3 deficient, which is why it is so important to supplement your diet with them. The main flax seed oil benefits lie in its ALA fatty acid content. However, in order to be optimally effective ALA must be converted to long-chain Omega-3 fats in the body, and many people, especially the elderly, do not have efficient internal mechanisms to achieve this.
What is a better source of Omega-3 Fatty Acids?
Recent studies have shown that fish oil may be a better source for the Omega-3 fatty acids that your body needs. Fish oil, harvested from cold water fish, contains the fatty acids DHA and EPA. Research points to the fact that DHA and EPA have more therapeutic value than ALA found in flax seed oil. Also, DHA and EPA do not have to be converted, as they are already long-chain Omega-3 fats and are easily absorbed in the body.
So the Omega-3 fatty acids in fish oil are better for your health than those found in flax seed oil, because they are more easily utilized by your body and are more powerful and therapeutic. You can increase flax seed oil benefits by substituting or adding fish oil to your diet.
How Can You Find A High Quality Fish Oil Product?
Only fish oils contain the special benefits of DHA and EPA Omega-3 fatty acids. So it's important that you find a high quality fish oil product so you can get the maximum health benefits.
Some things to keep in mind:
1) Natural fish oils are oftentimes contaminated with heavy metals such as mercury.
2) Most fish oil in capsule form does not come from the country where it is harvested, meaning there are often additives to make sure it stays fresh through all the extra handling and processing.
3) Many fish oils contain low levels of DHA, which is the most important component.
Therefore, you need to find a pure fish oil product that does not have any of the drawbacks mentioned above.

This seems like good stuff here...
Artic Cod Liver Oil
Haven't tried them yet myself, but I much prefer liquids (flax, fish oil, whatever) to gels/gelcaps, mostly due to the fact that you can get so much more for your money; plus, you can be more exacting with how much you want and how many servings per day, etc.

Is there any truth to the reported estrogen blocking properties of flax oil? If so, by what mechanism does this occur?

The inhibitory effect of flaxseed on the growth and metastasisof estrogen receptor negative human breast cancer xenograftsis attributed to both its lignan and oil components.
Wang L, Chen J, Thompson LU.

Our previous studies have shown that dietary flaxseed (FS) can reduce the growth and metastasis of human estrogen receptor negative (ER-) breast cancer in nude mice. The aims of our study were to determine (i) whether the tumor inhibitory effect of FS was due to its oil (FO), lignan secoisolariciresinol diglycoside (SDG), or both components, and (ii) whether the effect on tumor growth was related to increased lipid peroxidation. Athymic nude mice were orthotopically injected with ER- breast cancer cells (MDA-MB-435) and 8 weeks later were fed either the basal diet (BD) or BD supplemented with 10% FS, SDG, FO, or combined SDG and FO (SDG + FO) for 6 weeks. The SDG and FO levels were equivalent to the amounts in the 10% FS. Compared to the BD group, the tumor growth rate was significantly lower (p < 0.05) in the FS, FO, and SDG + FO groups, in concordance with decreased cell proliferation and increased apoptosis; however, these did not significantly relate to the lipid peroxidation, indexed as malonaldehyde (MDA), in the primary tumors. Lung metastasis incidence was reduced (16-70%) by all treatments, significantly in the FS and SDG + FO groups. The distant lymph node metastasis was significantly decreased (52%) only in the FO group. Although the total metastasis incidence was lowered (42%) significantly only in the SDG + FO group, all treatment groups did not differ significantly. In conclusion, FS reduced the growth and metastasis of established ER- human breast cancer in part due to its lignan and FO components, and not to lipid peroxidation. (c) 2005 Wiley-Liss, Inc.
Dietary flaxseed enhances the inhibitory effect of tamoxifen on the growth of estrogen-dependent human breast cancer (mcf-7) in nude mice.

PURPOSE: This study determined the effect of 10% dietary flaxseed (FS) and tamoxifen (TAM), alone and in combination, on the growth of estrogen-dependent human breast cancer (MCF-7) in athymic mice with or without 17beta-estradiol (E2) supplementation. EXPERIMENTAL DESIGN: Ovariectomized mice received injection with MCF-7 cells, were implanted with an E2 pellet (1.7 mg), and fed the basal diet (BD). When tumor reached approximately 40 mm2, the E2 implant was removed, and mice were randomized to the following groups and maintained at either low (E2 pellet removed) or high E2 level (new E2 pellet implanted) for 6 weeks: (a) positive control with new E2 pellet, fed BD, (b) negative control with no E2 implant, fed BD, (c) TAM group with TAM pellet (5 mg) implant, fed BD, (d) FS group fed 10% FS, (e) FS+TAM group with TAM implant, fed 10% FS. Tumor growth was monitored weekly. RESULTS: At low E2 level, FS regressed the pretreatment tumor size by 74%. TAM regressed tumor initially but later induced an increase so that the tumor size was finally similar to the pretreatment size. A tumor regression >53% was induced by FS+TAM than by TAM alone. At high E2 level, FS, TAM, and FS+TAM inhibited the tumor growth by 22, 41, and 50%, respectively, compared with the positive control. Decreased tumor size was attributable to reduced tumor cell proliferation and increased apoptosis. CONCLUSIONS: FS inhibited the growth of human estrogen-dependent breast cancer and strengthened the tumor-inhibitory effect of TAM at both low and high E2 levels.
Lignans and tamoxifen, alone or in combination, reduce human breast cancer cell adhesion, invasion and migration in vitro.
Chen J, Thompson LU.

Flaxseed has been shown to reduce the metastasis of estrogen receptor negative (ER-) human breast cancer in nude mice. This study determined whether enterodiol (ED) and enterolactone (EL), metabolites of plant lignans exceptionally rich in flaxseed, and tamoxifen (TAM), alone or in combination, can influence the various steps of metastasis, that is, breast cancer cell adhesion, invasion and migration, of two ER- human breast cancer cell lines, MDA-MB-435 and MDA-MB-231. The inhibition by ED, EL or TAM (1-5 microM) of cell adhesion to Matrigel or extracellular matrices, fibronectin, laminin, and type IV collagen, as well as cell invasion was dose dependent in both cell lines. When ED, EL and TAM were combined at 1 microM, a greater inhibitory effect on cell adhesion and invasion was observed than with either compound alone. ED and EL at doses of 0.1-10 microM reduced cell migration, but TAM had no effect at 0.1 and 1 microM, and exhibited a stimulatory effect at 10 microM. It is concluded that lignans and TAM, alone or in combination, can inhibit the steps involved in the metastasis cascade. Although more investigations are required, the study also suggests that the intake of the lignan-rich flaxseed may not antagonize the effect of TAM in ER- breast cancer cells.

NordicNaturals is an excellent company. Great quality and molecularly-distilled, so mercury is not an issue. NAC works to bind and aid in excretion of mercury, fwiw.Originally Posted by shootmeagain

I have been taking flax seed oil my self for the past few months @ 3 tbls daily. Are you guys saying that flax seed oil is not benificial when it comes to the omega's? Would it be better to supplement with both? I just wanna make sure im gettiin everything i need.

I think I like the taste of Hemp oil better than Flax. Manitoba Harvest brand Hemp oil; got it at my local WholeFoods Market.

Fish oil is stil far better than flax. I only use flax once in a while to balance out the omega ratio or to combat sore joints. There are several articles over at www.mercola.com explaining the importance of fish oil over flax.
Dr. Mercola is also very keen on the use of pure coconut oil for cooking and supplementation. I've been experimenting with it for the last couple weeks and I have to say I'm noticing some effects from it..leaning out, skin texture improving, fewer cravings.

Yes but according to some the forms of saturated fats in coconut oil have health promoting properties as well as lipid stabilizing properties. Read some of the articles on mercola.com concerning this..I found it quite interesting. Mercola does sell coconut oil so one might take it all with a grain of salt..however I do trust Dr Mercola moreso than nearly any other health guru.
