Agree with most of what said so far. See my 10 points below. The one thing that made a significant difference to my other half's levels ie dropped from 6.4 to 5.3 in 8 weeks, is an old fashioned natural remedy that tastes totally disgusting, but is an absolute life saver. I stress this is well worth doing. Have your levels tested before you start, and again when finished, and you & your Doc will be amazed!
What to do . . . Peel 30 cloves of garlic (approx. 2 bulbs), and roughly chop 5 lemons, skin & all. Place in blender if you have one, and blend to as fine as possible. Place mixture in saucepan with 1 litre of water and bring to boil, then turn off and allow to cool. NB If you don't have a blender, you'll need to chop garlic & lemons as finely as possible first. Then when mixture cools, push it through a sieve/strainer.
Take 30ml (one cough medicine measure) every night 1/2 hour before, or after dinner, for 3 weeks. Have an 8 day break, then repeat for a further 3 weeks. It is recommended you do this twice yearly/6 monthly.

What it does is it dissolves the build up of plaque in your arteries, and as an added bonus it strengthens your immune system at the same time, while not suffering any odour at all, as the lemon neutralises that effect of the garlic.
NB We cook this outside on the bbq side burner, as it stinks your house out! So if you don't have one of those types of bbq's, use a portable gas stove outside, which I'm tipping most Land Rover owners would have!!
Also . . .
1. Avoid Cholesterol reducing drugs IF possible without endangering your health, as awful side effects.
2. Start every day with porridge made from scratch with good quality Traditional Rolled Oats, not Quick/Microwave Oats.
3. Add a tablespoon of LSA (Linseed,Sunflower,Almond) meal to porridge & desertspoon of organic raisins. If you must sweeten further, use good quality honey. Try to avoid adding milk by cooking to appropriate consistency. NB LSA available from Health Food Stores, or health food section of major supermarkets. Aldi stocks excellent Organic Raisins.
4. Take minimum 2 x 1000mg/1gm good quality Fish Oil per day, and up to 4. If you can source Krill, even better, although more expensive, but doesn't make your breath smell!
5. Avoid over refined carbohydrates ie white flour products, over processed wheat products.
6. Avoid dairy altogether, and all animal fat, especially red meat. Replace with fish, especially Salmon (preferably fresh fillets), and good quality organic chicken without skin. Can have Goats cheese. Marinated Goat Fetta is a great alternative, especially in salads.
7. Up your intake of good oils, like Avocadoes and Olives.
8. Basically stick to fresh fruit and vegetables, especially salad greens and tomatoes. If exercise difficult, at least try and do a couple of 10-15 minute brisk walks each day.
9. Reduce alcohol intake or cut out altogether if possible. Avoid Beer, and sugar laden mixers like Coke. If you must have Beer, get low carbohydrate one like Pure Blonde, Carlton Dry, or Aldi's Cape Cyan Natural Blonde. If Spirit drinker, use Soda Water as mixer. All other mixers are high in sugar, and even Sodium (salt)
10. Read ingredients on everything you buy, and avoid pre processed where possible, especially if high in sugar, sodium, or animal derived fats. Good quality Vegetable oils are fine.
All the best with it; I'll be interested to know how you get on Ean.
