Plant Sterols

[Guest guest]

In study, he was shooting for 2 grams a day. From the below study that

would be about 30 lbs on average. Of course, it was a therapeutic dose. In

his original study, he used just leafy greens fruits and nuts and got the same

results as the study where he added supplemental plant sterols.

" The median plant sterol content of vegetables was 14 (3.8-50) mg/100 g edible

portion. The highest concentrations were found in broccoli. Brussels sprouts,

cauliflower and olives. The median plant sterol content of fruits was 16 (3-44)

mg/100 g edible portion. The highest concentrations were found in oranges and

passion fruits. "

Plant sterols are known to have serum cholesterol lowering effects. A high

dietary intake might therefore have a positive impact on health. All food items

of vegetable origin contain some amount of plant sterols. The aim of this study

was to analyse the plant sterol content of vegetables and fruits commonly

consumed in Sweden, and to compare fresh and cooked samples of the same items.

Altogether 20 different vegetables and 14 fruits were analysed. All vegetables

and fruits were purchased in two shops in the city of Gothenburg, Sweden.

Lyophilization was performed within one month of the items being purchased. The

samples were frozen at -20 (C and analysed within six months, with a GLC method

after acid hydrolysis, alkaline hydrolysis and silylation with

tri-methylsilylether. The acid hydrolysis was done in order to detect the

fraction of glycosylated plant sterols, which are split during boiling with HCl.

The median plant sterol content of vegetables was 14 (3.8-50) mg/100 g edible

portion. The highest concentrations were found in broccoli. Brussels sprouts,

cauliflower and olives. The median plant sterol content of fruits was 16 (3-44)

mg/100 g edible portion. The highest concentrations were found in oranges and

passion fruits. The plant sterol concentrations were thus low in vegetables and

fruits commonly consumed in Sweden. A serum cholesterol lowering effect

attributed to the plant sterols in vegetables and fruits would therefore be of

limited significance.

Sterol content of foods of plant origin.

Available data on phytosterols from the world's literature have been compiled

and summarized. There still exists a paucity of data on the quantities of plant

sterols in many foods. More extensive data are available on the relative sterol

composition. Our compilation shows that plant oils are excellent sources of

phytosterols. Nuts and seeds contain moderate levels, and fruits and vegetables

generally contain the lowest concentrations of plant sterols. Analyses of the

minor sterols, namely, the delta5- and delta7-phytosterols, have become

available only recently.
