I have been on the paleo diet since June 2012 and following it very strictly. Up until 6 weeks ago my lipid panel was a mixed bag

Total cholestrol was up to 290 (creeping up from 220 in June)
HDL was 57
LDL was 197 ( LDL was 150 before I started with the Paleo diet)
TRIGLYCERIDES: 77 (DOWN FROM 150 before paleo)

I was mostly concerned with LDL going up and 6 weeks ago followed up the advice of Mark from the perfect health diet and started to increase my carb intake to 300 calories per day mostly from white rice and yams.

A week ago I did another blood test and my lipid panel results were:

Total : 250
HDL: 63
LDL: 152
TRIGS: 173

so now I am puzzled by why the TRIG number shot up? I was pretty close to 65 grams of carbs per day, it seems to lower my LDL number and Total Cholestrol. My ratios are fine but I thought that low carb intake was the main reason for lowering TRIGLYCERIDES. i ONLY INCREASED MY CARB CONSUMPTION by 40 grams a day, any thoughts of why the Trig number has shot up so high?

First, a disclaimer. The standard lipid profile is not perfect. There are many variables that can alter the results. I would encourage you to read this article- Cholesterol - what does the blood cholesterol test actually measure?. The only lipid test that directly measures all components is the NMR Lipo-profile.

If we assume your numbers to be true, then I would blame the white rice. It has a moderately high glycemic index and glycemic load as well.

Hope this helps.

It is a puzzler. When you increased your carbs, did they displace fat in your diet? Or did you add them 'on top'?

[sifardi]

I did not change anything else in my diet, I just increased my carbs.

While high intake of carbs can drive high trig numbers, I'm surprised yours would go up based on adding the little bit that you did. I eat more starch than that and my last trig number was 49. I always have them with fat (butter on potato or rice, coconut oil on sweet potatoes, etc), so that may make a difference.

Were you fasting when the sample was taken?

[sifardi]

I did fast for 9 hours prior the test (did not eat after dinner and took the test early morning)

[magicmerl]

Maybe just write it off as one of those things and see what the next test shows.
