I recently had a round of blood tests; my C-reactive protein was less than 1 (the quack says it should be <5).   I wonder if that is due to nearly total avoidance of seed oils (canola, soy, sunflower, etc) and stick to butter, coconut and olive oil.

It's not.

Polyunsaturated fatty acids and serum C-reactive protein: the Rotterdam study.
Muka T, Kiefte-de Jong JC, Hofman A, Dehghan A, Rivadeneira F, Franco OH.

We aimed to investigate whether dietary intake of total or individual (n-3, n-6, and n-3:n-6 ratio) polyunsaturated fatty acids (PUFAs) was prospectively associated with serum levels of C-reactive protein (CRP), a marker of inflammation. We analyzed 4,707 participants (1,943 men and 2,764 women) from the Rotterdam Study, a prospective follow-up study of subjects aged 55 years or older in the Netherlands. At baseline (1989-1993), dietary intake of PUFAs was assessed by validated food frequency questionnaire. CRP was measured at baseline and at the third study visit (1997-1999). Regression coefficients (β) and 95% confidence intervals were obtained using linear generalized estimating equations. Dietary intake of butter and margarine explained most of the variance in PUFA intake. After adjustment for possible confounding factors, higher intake of total PUFAs was associated with lower CRP levels (fourth quartile vs. first quartile: β = -0.08, 95% confidence interval: -0.15, -0.01). Similarly, intake of n-6 PUFAs was inversely related to CRP (fourth quartile vs. first: β = -0.09, 95% confidence interval: -0.16, -0.01). No consistent trends were observed regarding n-3 PUFAs or n-3:n-6 PUFA ratio and CRP. These findings suggest that high intakes of total PUFAs are associated with lower levels of CRP, reflecting diminished chronic systemic inflammation, which in our study was mainly driven by n-6 PUFAs.

The Associations of C-Reactive Protein with Serum Levels of Polyunsaturated Fatty Acids and Trans Fatty Acids Among Middle-Aged Men from Three Populations.

El-Saed A(1), Masaki K, Okamura T, Evans RW, Nakamura Y, Willcox BJ, Lee S, Maegawa H, Seto TB, Choo J, Fujiyoshi A, Miura K, Kuller LH, Ueshima H, Sekikawa A; ERAJump Study Group.

 BACKGROUND: C-reactive protein (CRP) and many fatty acids (FAs) have been linked to cardiovascular disease. Associations of serum CRP with FAs in different populations have not been established. METHODS: Participants were 926 men aged 40-49 (2002-2006) from a population-based sample; 310 Whites from Pennsylvania, U.S., 313 Japanese from Shiga, Japan, and 303 Japanese Americans from Hawaii, U.S. Serum CRP (mg/L) was measured using immunosorbent assay while serum FAs (%) were measured using capillary-gas-liquid chromatography. RESULTS: Whites had CRP (mg/L) levels higher than Japanese with Japanese Americans in-between (age-adjusted geometric mean "GM" 0.96, 0.38, 0.66, respectively). Whites had also higher levels of total n-6 FAs (%) and trans fatty acids (TFAs) but lower levels of marine-derived n-3 FAs compared to Japanese (41.78 vs. 35.05, 1.04 vs. 0.58, and 3.85 vs. 9.29, respectively). Japanese Americans had FAs levels in-between the other two populations. Whites had significant inverse trends between CRP and tertiles of total n-6 FAs (GM 1.20, 0.91 and 0.80; p=0.002) and marine-derived n-3 FAs (GM 1.22, 1.00 and 0.72; p<0.001) but a significant positive trend with TFAs (GM 0.80, 0.95 and 1.15; p=0.007). Japanese had a significant inverse trend between CRP and only total n-6 FAs (GM 0.50, 0.35 and 0.31; p<0.001). Japanese Americans had CRP associations with n-3 FAs, n-6 FAs, and TFAs similar to but weaker than Whites. CONCLUSIONS: With the exception of consistent inverse association of CRP with total n-6 FAs, there are considerable variations across the three populations in the associations of CRP with different FAs.
