- Palm and coconut oils possess remarkable nutritional and functional properties
- Dietary fats are crucial sources of energy for particularly infants and children in developing countries
- Palm oil plays a crucial role as it is commonly used in many stews, gravies and soups eaten with starchy staples in Ghana.
- Palm oil contains alpha-, beta- and gamma-carotenes
- Precursors of vitamin A
- In Ghana vitamin A deficiency is a major problem among both adults and children
- Using palm oil in meals in moderate amounts is a relatively affordable means of ensuring adequate vitamin A intake.
- Palm oil contains phytosterols such as lipophilic sterols:
- Sitosterol,
- Stigmasterol
- Campesterol
- Easily absorbed in the gastrointestinal tract
- Then converted through a series of enzymatic reactions into cholesterol
- Major precursor of steroid hormones.
- Squalene
- Excess amounts has been found
- Possess a negative feedback inhibition activity on the function of HMG-CoA reductase
- Moderate use of palm oil is likely to be beneficial for blood lipid profiles.
- Palm oil is rich in vitamin E
- Mainly of tocopherols and tocotrienols
- Tocotrienols could reduce plasma cholesterol, apolipoprotein B, thromboxane B2, and platelet factor IV
- Could also inhibit or delay the oxidative deterioration of cellular membranes
- Adulteration of palm oil with the high levels of Sudan IV dye
- Chemical reported to have carcinogenic potential
- Confiscation of large quantities of palm oil from several markets in Accra by the Food and Drugs Authority (FDA) following positive laboratory tests

- Palm oil contains
- 50 % MUFA
- 50 % SFA [9]
- Palm oil
- Obtained from the mesocarp of the palm fruit composed of:
- 50% saturated fatty acids
- Trace amounts of lauric and myristic acids
- More potential to raise total and LDL cholesterol concentrations
- Large amount of palmitic acid (44%)
- Is less potent in that regard
- 40% monounsaturated fatty acids
- 10% polyunsaturated fatty acids
-palm oil is used directly in a variety of food processes without undergoing a hydrogenation process
- Palm oil does not contain any trans- unsaturated fatty acid isomers
- Sundram, Sambanthamurthi reported that, when palm oil is consumed as part of a low-fat diet (<30% energy) !!
- Shown to be effective in maintaining desirable plasma cholesterol and lipoprotein cholesterol levels
- Triglyceride species in palm oil
- Palmitic acid at the alphaposition of the molecule
- Confers the non-hypercholesterolaemic property to the oil [4]
