It's only the LDL that is high (not sure what the lipoprotein 5.8 is. I thought the HDL and LDL were lipoproteins). Trigs and HDL are fine, in fact HDL is very good.
It is thought the ratio of trigs and HDL is the important one. This should be under 0.87mmol/l to be ideal. Yours is 0.9 so not far out.
The usual advice for high LDL is to eat as much omega 3 and antioxidants as you can:
dark chocolate, avocado, 1 glass red wine, black and green tea, almonds, walnuts, pistachios, salmon, sardines, mackerel, tuna, olive oil, beans and lentils, berries, seeds (especially flax and chia). If you eat Lidl High Protein rolls, they are full of omega 3.
