Vegetable oils are the richest foods in phytosterols. Beans, whole grains, spices, seeds, nuts, fruits, and vegetables are also excellent dietary sources!
What phytosterols do to the body?
Phytosterols are compounds which are found in plants. Foods from animal sources don’t contain any phytosterols. Phytosterols are structurally related to cholesterol. There are 2 types of phytosterols; stanols and sterols.
We can’t synthesize phytosterols. We have to get them from food.
Above all, phytosterols can significantly lower serum LDL-cholesterol. According to studies, a daily phytosterol dose of 2g lowers LDL-cholesterol up to 10%.
Moreover, following a diet rich in phytosterols may be beneficial for people with cardiovascular issues, or diabetes.
Additional, phytosterols may lower the risk of certain cancers. But, further studies are needed.
Which diet is rich in phytosterols?
Nowadays, most people get 150-800 mg of phytosterols a day from diet. Vegans and vegetarians consume the highest amounts of phytosterols.
The average Western diet contains between 160-400 mg of phytosterols a day. On the other hand, a plant-based diet or vegan diet contains 600-800 mg of phytosterols a day. A high-phytosterol plant-based diet contains up to 5 times more phytosterols than the average Western diet.
Although phytosterols are present naturally in many common foods, we absorb only a fraction of them. We absorb less than 5% of plant sterols and less than 0.5% of plant stanols! In comparison, we absorb about 50%-60% of dietary cholesterol.
Hence, although diets typically contain similar amounts of phytosterols and cholesterol, our serum phytosterol concentrations are usually several hundred times lower than serum cholesterol concentrations!
How many phytosterols do we need a day?
Consuming high amounts of unrefined vegetable oils, vegetables, fruits, and nuts is enough to significantly boost our daily intake of phytosterols
Our ancestors used to follow a diet rich in phytosterols, containing about 1,000 mg a day.
According to the National Cholesterol Education Program, a daily phytosterol intake of 2,000 mg is enough. We can get about 30% of this recommended dose from food. Especially if we follow a whole food plant-based diet.
As a rule of thumb, we shouldn’t take more than 3,000 mg of phytosterols a day. Higher doses don’t have any further health benefit. On the contrary, pretty high doses of phytosterols from supplements might cause adverse effects.
Vegetable oils are the richest foods in phytosterols!
Unrefined vegetable oils contain the highest concentration of naturally occurring phytosterols! Just 1 tbsp of many common vegetable oils can boost your daily intake!

What foods are good sources of phytosterols?
If you follow a whole food plant-based diet, you’ll get high doses of phytosterols. Seeds and nuts are particularly high in phytosterols. Whole grains and beans are also excellent sources. Even fruits and vegetables greatly contribute to the daily phytosterol intake!
