- Saturated fat is the main food driver of high LDL. Ghee, butter, coconut and palm oil, fatty meat and full-fat cheese are the biggest sources.
- Coconut oil raised LDL by about 10 mg/dL compared with vegetable oils in a review of 16 trials.
- Trans fats from vanaspati and some fried and baked foods are the most harmful fats of all.
- Swapping saturated fat for unsaturated fat lowered heart disease by about 30% in trials.
If your LDL cholesterol is high, it helps to know which foods push it up. The biggest culprits are not always the ones people expect. Eggs and prawns get a lot of blame, but for most people the real drivers are saturated fat and trans fat, often hidden in cooking fats, snacks and baked goods.
The aim is not to ban foods. It is to eat less of the ones that raise LDL and replace them with better choices. What you eat instead matters as much as what you cut. Replacing ghee with sugar or refined flour does not help your heart.
How saturated fat raises LDL
Your liver clears LDL from the blood using LDL receptors on its surface. Saturated fat reduces the number and activity of these receptors, so more LDL stays in circulation. Guidelines advise keeping saturated fat below 10% of daily calories, and lower if your LDL is high. For someone eating 2,000 calories, 10% is about 22 g a day.
The chart below shows roughly how much of each common cooking fat is saturated. The higher the share, the more it tends to push LDL up when used every day.
Approximate share of saturated fat in each fat or oil, from standard food composition tables; values vary by brand and source.
Foods to limit
Common in Indian cooking and sweets. Use small measured amounts for flavor, not as your main cooking fat.
Often sold as healthy, but both raise LDL. Palm oil is common in packaged snacks, biscuits and namkeen.
Mutton with visible fat, sausages, bacon, salami and keema made from fatty cuts.
High in saturated fat. Choose smaller portions or lower-fat versions.
Puffs, cakes, biscuits, samosas and pakoras often combine saturated or trans fat with refined flour.
Coconut oil: what the trials show
A 2020 review of 16 clinical trials found that coconut oil raised LDL by about 10 mg/dL compared with non-tropical vegetable oils such as olive, soybean or sunflower oil. It also raised HDL slightly, but that does not cancel out the rise in LDL. If you cook with coconut oil, as many families in South India do, try mixing in or switching to groundnut, rice bran or sunflower oil for everyday cooking.
Hidden sources in everyday meals
Much of the saturated fat people eat does not come from the jar of ghee in the kitchen. It comes from restaurant curries finished with butter and cream, biryani cooked in ghee, sweets made with khoa and vanaspati, pizza and burgers with cheese, and packaged snacks made with palm oil. Eating out or ordering in a few times a week can add more saturated fat than home cooking all week. When you do eat out, choose tandoori or grilled dishes, dal, chana and vegetable sabzi over creamy gravies, and share rich sweets.
Trans fats: the worst of all
Industrial trans fats form when vegetable oil is partly hydrogenated to make it solid. They raise LDL and lower HDL at the same time. The main source in India has been vanaspati, a hydrogenated vegetable fat used in bakeries, sweet shops and street food. Oil that is reused many times for deep frying can also form some trans fat. The World Health Organization has called for industrial trans fat to be removed from the global food supply, and India and many other countries now limit it by law.
- Check labels for “partially hydrogenated” oils and choose products with 0 g trans fat.
- Limit bakery biscuits, puffs, khari and fried snacks from unknown oils.
- At home, avoid reusing frying oil again and again.

Unfiltered coffee
Coffee beans contain natural oils called cafestol and kahweol, which raise LDL. Paper filters trap most of them. Boiled coffee, French press and Turkish coffee let them through. A meta-analysis of trials found that boiled coffee raised cholesterol, while filtered coffee had little effect. If your LDL is high and you drink several cups of unfiltered coffee a day, switching to paper-filtered or instant coffee is an easy change.
Eggs and dietary cholesterol
Dietary cholesterol, found in eggs, prawns and organ meats, has a smaller effect on blood LDL than saturated fat for most people. Some people are more sensitive to it. The American Heart Association says healthy adults can include up to one whole egg a day as part of a healthy diet. Eggs are often eaten with butter, cheese, bacon or parathas, and those partners are frequently the bigger problem.
Better swaps
Trials that replaced saturated fat with polyunsaturated fat, from vegetable oils, nuts and seeds, lowered heart disease by about 30%. Pair these swaps with the foods in Foods That Lower Cholesterol for the best effect, and see How to Lower LDL Cholesterol for a full plan.
- Ghee, butter, cream, vanaspati
- Coconut and palm oil
- Fatty and processed meat
- Bakery items and fried snacks
- Mustard, groundnut, olive or canola oil
- Nuts, seeds and avocado
- Fish, pulses and tofu
- Oats, barley and whole grains
MythGhee and coconut oil are traditional, so they must be good for cholesterol.
FactBoth are high in saturated fat and raise LDL compared with vegetable oils. Small amounts for flavor are fine, but they are not heart-healthy cooking fats.
Common questions
Is a little ghee okay?
Yes, a teaspoon for flavor fits most diets. The problem is using it as the main cooking fat every day.
Should I cut out eggs completely?
Usually not. Up to one egg a day is fine for most healthy adults. If you have diabetes or very high LDL, ask your doctor what suits you. Understanding Cholesterol Numbers explains how to read your results.
Does sugar raise LDL?
Sugar and refined carbs mainly raise triglycerides and lower HDL rather than LDL. They are still worth limiting for your heart and blood sugar.
- Saturated fat is the main food driver of high LDL.
- Trans fats from vanaspati and reused frying oil are the most harmful.
- Unfiltered coffee can raise LDL; paper filters help.
- For most people, eggs matter less than the fats eaten with them.
