Phytosterols are plant sterols structurally similar to cholesterol that act in the intestine to lower cholesterol absorption. The term phytosterols covers plant sterols and plant stanols. Plant sterols are naturally occurring substances present in the diet principally as minor components of vegetable oils. Plant stanols, occurring in nature at a lower level, are hydrogenation compounds of the respective plant sterols. Plant sterols and their hydrogenated forms, stanols, have attracted much attention because of their benefits to human health in reducing serum and LDL cholesterol levels, with vegetable oil processing being their major source in several food products currently sold. The predominant forms of plant sterol end products are sitosterol, stigmasterol, campesterol and brassicasterol (in brassica).Sterols are present in both plants as well as animals. Animal sterols are nothing but cholesterol, while plant sterols or phytosterols are plant versions of cholesterol. They are compounds found naturally in the cell walls of plants and are present in small amounts on all kinds of fruits, vegetables, grains, legumes, nuts, seeds, etc.

Special Precautions of Plant Sterols
Over 80 studies conducted have shown no signs of any side effects when plant sterols are taken in appropriate amounts. However, when taken in high doses, certain mild side effects are seen to have occurred. The different side effects are:
- Heartburn
- Indigestion
- Nausea
- Diarrhea
- Constipation
- Erectile Dysfunction or Impotence
- Decreased sex drive
The benefits of Plant Sterols are
- Studies suggest that plant sterols may help keep cholesterol in check by inhibiting the intestines' absorption of cholesterol. In doing so, plant sterols help to reduce circulating levels of cholesterol and lower your levels of LDL ("bad") cholesterol.
List of Foods (with High Phytosterol) That Help Lower Serum Cholesterol
In the following table is a list of foods high/low in phytosterols. Generally, oils have high phytosterol content where as vegetables and fruits have lower content. The phytosterol content presented below is the sum of beta sitosterol, campesterol, and stigmasterol.
