Nice collection of ads you have there, not.

While omega-3s are important, it is getting more difficult to get them
from seafood without exposing yourself to man-made pollution (PCBs,
Dioxins, PBDEs, and mercury).

The same problem exists, if you take your fish in pill form.

Fish oil supplements have sometimes come under scrutiny in recent years.
In early 2006, government agencies such as the Food Standards Agency in
the UK and the Food Safety Authority of Ireland reported PCB levels that
exceeded the strict new European maximum limits in several fish oil
brands,[4][5] which required temporary withdrawal of these brands.

If you're taking fish oil for your health, you may want to rethink your
next pill. According to a lawsuit filed in California on Tuesday, many
popular fish oil companies knowingly sell products with unnecessarily
high levels of polychlorinated biphenyl (PCB) compounds‹despite claims
on the label that the product has been treated and is safe from PCB
contamination. . .

. . . Eight companies are named in the suit‹CVS Pharmacy, Inc.; General
Nutrition Corp. (GNC); Now Health Group, Inc.; Omega Protein, Inc.;
Pharmavite LLC (Nature Made brand); Rite Aid Corp.; Solgar, Inc.; and
TwinLab Corp.‹and others are likely to be added as further testing is
carried out.

Flax oil is still good, as is purslane, commonly considered a weed but
has the highest concentration of omega-3s of any terrestrial plant.

Common purslane: a source of omega-3 fatty acids and antioxidants

Center for Genetics, Nutrition and Health, Washington, DC 20009.

omega-3 fatty acids, alpha-tocopherol, ascorbic acid, beta-carotene and
glutathione determined in leaves of purslane (Portulaca oleracea), grown
in both a controlled growth chamber and in the wild, were compared in
composition to spinach. Leaves from both samples of purslane contained
higher amounts of alpha-linolenic acid (18:3w3) than did leaves of
spinach. Chamber-grown purslane contained the highest amount of 18:3w3.
Samples from the two kinds of purslane contained higher leaves of
alpha-tocopherol, ascorbic acid and glutathione than did spinach.
Chamber-grown purslane was richer in all three and the amount of
alpha-tocopherol was seven times higher than that found in spinach,
whereas spinach was slightly higher in beta-carotene. One hundred grams
of fresh purslane leaves (one serving) contain about 300-400 mg of
18:3w3; 12.2 mg of alpha-tocopherol; 26.6 mg of ascorbic acid; 1.9 mg of
beta-carotene; and 14.8 mg of glutathione. We confirm that purslane is a
nutritious food rich in omega-3 fatty acids and antioxidants.
