higher intakes of marine-derived omega-3 fatty acids EPA and DHA which appear to be protective in non Hodgkin’s Lymphona (NHL)

Sunday, July 17th, 2011


In this population-based study, the dietary intake of various nutrients as well as the consumption of marine-derived omega-3 fatty acids and fish consumption was compared in 591 cases of non-Hodgkin’s Lymphoma (NHL) and compared to 460 healthy controls from a Swedish population (residents aged 18-27 years). A highly-significant inverse relationship between the intake of marine-derived omega-3 fatty acids as docosahexaenoic acid (DHA) plus eicosapentaenoic acid (EPA) combined and the risk of NHL was observed. With increasing intakes of DHA/EPA (combined) of >300 mg per 1000 kcal, a 40% lower risk of NHL was indicated as compared to those consuming less than 100 mg per 1000 kcal. Interestingly, no significant relationship between the consumption of total omega-3 fatty acids (which would include DHA/EPA plus a-linolenic acid which is consumed in much higher amounts than DHA/EPA) or omega-6 fatty acids and the risk of NHL was found. In addition, the authors reported that higher consumptions of fish (including salmon, mackerel, herring, cod) were also inversely correlated in a significant manner with the risk of NHL.

(It is noteworthy that the paper reports fish consumptions in fish servings/day ranging from <1.5 up to =3.0 in the higher intake sector. Upon evaluation of this paper, the DHA/EPA Omega-3 Institute contacted the lead author regarding an apparent error and has been assured by the lead author that the reported fish servings ‘per day’ as reported should actually have been in fish servings ‘per week’.)

Non-Hodgkin’s Lymphoma (NHL) – Lymphomas are cancers of the immune system involving lymphocytes (white blood cells) which can be sub-divided into non-Hodgkin’s lymphomas (NHL) and Hodgkin’s disease. In NHL, the white blood cells can progress abnormally within the lymph nodes and can also involve other organs associated with the immune system. While it may occur at any age, deaths due to NHL occur more often amongst the elderly (over the age of 65 years). Although a relatively uncommon cancer, the incidence of NHL is increasing rapidly in North America for unknown reasons.

Dr. Holub’s Comments:

Considering the surge in the frequency of NHL in North America and elsewhere during recent years, potential dietary strategies and public health advice for reducing the development of NHL are of considerable interest. This population-based study is therefore of potential importance in this regard. The higher intakes of marine-derived omega-3 fatty acids which appear to be protective against NHL (>300 mg per 1000 kcal) would amount to approximately 650 mg of DHA/EPA (combined) per day based on a daily caloric intake of approximately 2,150 kcal per day. It is interesting to note that this intake (650 mg/day) is the recommended acceptable intake suggested at the ISSFAL workshop held in 1999 in Bethesda , Maryland by a group of scientific experts who met to evaluate omega-3 fatty acids for overall health (J. Am. Coll. Nutr. 18: 487-489, 1999).

As noted (see above), in Prof. Holub’s conversation and correspondence exchange with Dr. Ellen Chang (lead author of this new release), = 3.0 servings of fatty fish per week (and not per day as stated in the original text of the published paper) provided an approximate 50% lower observed incidence of NHL as compared to fatty fish servings of <1.5 per week.

Summary:

Omega 3 EPA reduces LDL cholesterol levels – TakeOmega3 has 750mg EPA per capsule

Wednesday, December 15th, 2010

New clinical study results presented at the American Heart Association Scientific Sessions show that the long-chain omega-3 fatty acid EPA (eicosapentaenoic acid), helped significantly reduce small dense LDL (bad) cholesterol levels.

“This study suggests that supplementation with the omega-3 fatty acid EPA may present unique benefits for cardiovascular health,” said Sujata K. Bhatia, M.D., Ph.D., research associate with DuPont. “EPA was shown to have advantageous effects on several biomarkers, including LDL cholesterol, small dense LDL, and lp-PLA2.”

EPA is a long-chain fatty acid that is found primarily in cold water, fatty fish like sardines anchovies mackerel  as well as some omega-3 fatty acid such as TakeOmega3 which has 750 mg EPA per capsule  and is the highest grade omega 3 available in UK . A growing body of evidence suggests that EPA is the long-chain omega-3 that supports heart health.

The study, conducted by Cardiovascular Research Associates and sponsored by DuPont, was conducted among 110 healthy individuals comparing the effects of EPA supplements to DHA (docosahexaenoic acid) supplements on cardiovascular health. The participants were placed into four study groups and examined over a six week period. During that time, each group was monitored while taking: EPA 600 mg per day; EPA 1,800 mg per day; DHA 600 mg per day; and an olive oil placebo.

The study found that in the 1,800mg EPA group, there were significant reductions of 7 percent for small dense low density lipoprotein (LDL) cholesterol, and 6 percent for lipoprotein-associated phospholipase A2 (lp-PLA2). lp-PLA2 is an enzyme involved in vascular inflammation.
In contrast, the 600mg DHA group showed a significant increase in total small dense LDL cholesterol in both the fasting and fed state of 14.2 percent and 16.3 percent respectively.

The study results will be featured during the American Heart Association Conference poster session in Chicago
