I'd say go and get another cholesterol test. You should look at trigs, TC, HDL, and LDL as a minimum. Then get it checked every 6-12 months and look for trends. If you are eating as you say, you should have no worries, and certainly shouldn't base your fears on one cheap test. Plus, you are so close to being 'in range' it's ridiculous! Test again in a year and look for a trend.
LDL elevation can also be caused by low thyroid hormones, so maybe if there's one area your could improve your diet on, it would be to add more carbs, into the 100-200g/day range, and carbs from quality starch sources like potato, sweet potato, plantains, rice.
