How to change your diet if cholesterol is elevated?

Basic information: how does diet affect cholesterol?

Blood cholesterol levels are not solely dependent on the amount of cholesterol obtained from food. The body – particularly the liver – regulates cholesterol production in a complex manner. Diet especially affects LDL cholesterol (bad cholesterol), which is the most significant risk factor for cardiovascular diseases.The most important nutritional factors are:

  • Quality of fat

  • Fiber content

  • Amount of simple carbohydrates

  • Total energy intake

  • Intake of plant sterols and beta-glucan

Dietary changes can reduce LDL cholesterol by up to 5–20% without medication. With medication, the effect can be even greater.

What to focus on in dietary changes?

1. Reduce the amount of saturated fats


Saturated fats (solid fats) raise blood LDL cholesterol. They are particularly found in:

  • Butter and butter-based spreads

  • Fatty cheeses and cream

  • Fatty meats and sausages

  • Baked goods, cookies, and ready meals

Options :

  • Use margarine or vegetable oil (e.g., rapeseed, olive)

  • Choose low-fat dairy products

  • Use vegetable oil for frying instead of butter

2. Add soft or unsaturated fats


Soft fats improve the fat profile and can raise HDL cholesterol. Good sources include:

  • Plant oils: rapeseed, olive, grape seed, avocado oil

  • Nuts and seeds

  • Fatty fish (salmon, sardines, mackerel)

  • Avocado

Recommendation: Replace saturated fats with unsaturated fats, do not eliminate fats completely.

3. Eat more soluble fiber


Soluble fiber (e.g., beta-glucan) binds cholesterol and prevents its absorption. Good sources:

  • Oat products (porridge, oat bran, oat drinks)

  • Apples, pears, berries

  • Legumes (lentils, beans, chickpeas)

  • Psyllium

Goal: At least 5–10 g of soluble fiber per day, as part of a broader fiber goal (25–35 g/day).

4. Limit sugar and white grains

High intake of sugar and refined carbohydrates increases triglycerides and may lower HDL cholesterol.Avoid:

  • Sweets, sugary drinks, juices

  • White bread, rice, pasta

  • Breakfast cereals and "health snacks" with added sugar

Replace with: whole grain products, rye bread, brown rice, oat-based alternatives

5. Add more vegetables, fruits, and berries


Vegetables contain fiber, antioxidants, and phytochemicals that protect the arteries. Goal:

  • At least 500 g of vegetables, fruits, and berries per day

  • Include something fresh or cooked in every meal

6. Add plant sterols if possible


Plant sterols prevent the absorption of cholesterol in the intestines. Available, among others:

  • Special margarines (e.g., Benecol, Becel ProActiv)

  • Dietary supplements (plant sterol capsules)

  • In some plant-based drinks

Effect: Can lower LDL cholesterol by up to 10–15%.

7. Avoid trans fats


Trans fats raise LDL and lower HDL.They have largely been removed from Finnish food products, but may still be present:

  • In foreign pastries

  • In fried fast foods

  • In foods that contain "partially hydrogenated vegetable fat"

Check the product labels.

Frequently Asked Questions (FAQ)

1.Should you start lowering cholesterol even if the levels are only slightly elevated?

Yes. The earlier you make changes, the more likely you are to avoid medication and long-term consequences.

2. Can cholesterol be lowered without medication?

Often yes, especially in mild cases. Diet and exercise may be sufficient if other risk factors are under control.

3. Can you eat eggs if cholesterol is high?

In moderation, yes.According to new recommendations, the cholesterol content of eggs does not affect blood cholesterol as strongly as previously thought.

4. How much oats is needed daily to lower cholesterol?

At least 3 g of beta-glucan per day, which corresponds to, for example, 40 g of oat flakes or 1.5 dl of oatmeal.

5. How quickly does the effect of diet show in blood tests?

The first effects may be visible as early as 4 weeks, but to assess the full benefit, a blood test is recommended at 2–3 months.
