None of the above, except for the oils.  Disappointingly, Anchell
doesn't forbid any oils, except for margarine.

Speaking of oils, the following study is somewhat surprising:

Does vegetable oil attenuate the beneficial effects of fish oil
in reducing risk factors for cardiovascular disease?

Contradictory reports on the protective effect of fish
consumption on cardiovascular disease (CVD) risk could be due to
variations in the intake of n-3 and n-6 polyunsaturated fatty
acids (PUFAs). Metabolic competition between n-3 and n-6 PUFAs
suggests that n-6 PUFAs in vegetable oils could attenuate the
efficacy of n-3 PUFAs in fish oil to favorably alter endpoints
relevant to CVD risk. We determined the effects of varying
dietary amounts of fish oil on lipid and thrombotic endpoints
relevant to risk factors for CVD and whether these effects were
attenuated by vegetable oils. Two randomized, double-blind,
placebo-controlled, parallel studies were conducted in human
subjects fed varying amounts of n-3 and n-6 PUFAs; n-3 PUFA
intake was varied by using fish or placebo oil capsules, and n-6
PUFA intake was modified by incorporating varying amounts of
safflower oil into the diet. Endpoints included changes in
membrane fatty acid composition, blood lipids, and thrombotic
profile. The results indicated that absolute amounts of fish oil,
and not the relative amounts of fish and vegetable oil (ratios of
n-3 to n-6 PUFAs), determined the magnitude of the reduction of
arachidonic acid and increase in eicosapentaenoic acid in
phospholipids of plasma and platelets. The suppression of plasma
triacylglycerols by fish oil was not affected by varying amounts
of dietary n-6 PUFAs. Fibrinogen concentrations decreased with 15
g but not with 9 g fish oil/d fed at the same ratio of n-3 to n-6
PUFAs. The efficacy of fish oil in favorably modifying certain
risk factors for CVD was not attenuated by vegetable oil.
