Article
Full-text available
It is not clear whether a saturated fatty acid-rich palm olein diet has any significant adverse effect on established surrogate lipid markers of cardiovascular disease (CVD) risk. We reviewed the effect of palm olein with other oils on serum lipid in healthy adults. We searched in MEDLINE and CENTRAL: Central Register of Controlled Trials from 1975...
Chapter
Cooking oil serves as an important energy source for daily dietary fat intake. Fat plays important physiological roles in normal individuals and even more in individuals with a need for higher energy intake such as sportsmen, hence has a major role in sports nutrition. This review attempts to discuss the types of cooking oils available and their ba...

Chemically-interesterified (CIE) fats are trans-fat free and are increasingly being used as an alternative to hydrogenated oils for food manufacturing industries to optimize their products’ characteristics and nutrient compositions. The metabolic effects of CIE fats on insulin activity, lipids, and adiposity in humans are not well established. We i...

High-oleic blended cooking oil (HOBO) comprises palm olein and canola oil, with more than 50% of monounsaturated oleic acid. Studies on the effects of HOBO on human health is limited and therefore, this study compared the effects of HOBO, extra virgin olive oil (OO) and coconut oil (CO) on biomarkers of inflammation, obesity and blood pressure in 3...

Palm Based High-Oleic Cooking Oil and Extra Virgin Olive Oil Diets do not Affect Markers of Insulin Resistance and Glucose Tolerance in Overweight Adults Background: High oleic blended cooking oil (HOBO) is an oil product of blended palm olein and canola oil with monounsaturated oleic acid as dominant fatty acid. This blend has increased the amount...

Full-text available
Effects of high-protein diets that are rich in saturated fats on cell adhesion molecules, thrombogenicity and other nonlipid markers of atherosclerosis in humans have not been firmly established. We aim to investigate the effects of high-protein Malaysian diets prepared separately with virgin olive oil (OO), palm olein (PO) and coconut oil (CO) on...
Article
Full-text available
Carotenoid-rich red palm oil (RPO)-based snacks have been provided to children in impoverished communities to improve their vitamin A status. The non-availabilty of information on the acceptability of RPO-based snacks by Malaysian aborigines (Orang Asli) children forms the basis of this study. Twenty-one Orang Asli children, majority of whom had no...
Article
This paper outlines the methodology to add glycaemic index (GI) and glycaemic load (GL) functionality to food DietPLUS, a Microsoft Excel-based Malaysian food composition database and diet intake calculator. Locally determined GI values and published international GI databases were used as the source of GI values. Previously published methodology f...

Full-text available
Dietary fat type is known to modulate the plasma lipid profile, but its effects on plasma homocysteine and inflammatory markers are unclear. We investigated the effects of high-protein Malaysian diets prepared with palm olein, coconut oil (CO), or virgin olive oil on plasma homocysteine and selected markers of inflammation and cardiovascular diseas...
Article
The teaching and research tool called 'DietPLUS', developed by the present author at an institution of higher learning in 2007, contains nutrient information of 840 food items in Excel format. DietPLUS functions as a '2-in-1' food composition database plus a rapid calculator of nutrient intakes, with the option of 'collapsing' the food composition...
Article
The present study is unique in the Malaysian context on two counts; first, it employs for the first time a functional group approach (groups based on occupational or economic activity) in the assessment of community nutritional status. Second, the study provides on a nationwide-sampling basis, information on total blood cholesterol (TC) levels in r...
Article
Full-text available
As a part of the recent UPM-IMR collaborative study on the nutritional status of communities in rural villages and estates in Peninsular Malaysia from 1992-1995, this report presents findings on the haemoglobin levels and the prevalence of anaemia amongst these rural dwellers. A total of 69 villages and 7 estates located in 9 states in Peninsular M...
Article
Full-text available
The theoretical impact of the use of coconut cream (santan) powder and palm oil santan powder on the dietary levels of C12-16 saturated fatty acids (SFAs) and linoleic acid (18:2), and on serum total cholesterol (TC), was evaluated holding non-santan dietary variables constant. The prediction was based on a 2,300-kcal hypothetical diet, containing...
Article
Full-text available
Fasting serum specimens from (a) 217 male and 46 female patients with coronary artery disease (CAD), aged 35-75 years, who had undergone angioplasty (PTCA) / coronary artery bypass graft (CABG), and (b) 160 apparently healthy controls (106 males, 54 females, aged 30-75 years), were assessed for serum lipid profile. Both sex and ethnicity significan...

Full-text available
This paper highlights the marked presence of nutritional disorders in a sample (190 males, 237 females, aged 18-80 years) obtained from the adult population in three kampungs i.e. Pasang Api, Sungai Nipah Baroh and Sungai Balai Darat, in the Mukim of Bagan Datoh, Perak in 1992. All subjects (except pregnant females) were measured for blood pressure...
Article
An examination of the fat composition of the diet of a Malaysian urban hostel population obtained by chemical analysis of representative meals prepared by a 7-day rotation menu, revealed both nutritional attributes and limitations when compared against the dietary messages contained in the American Heart Association (AHA) and World Health Organisat...
Article
This paper reviews recent reports of the cholesterolaemic effects of palm oil. The evidence indicates that the substitution of palm oil or its lipid fractions for the usual fats in the diet does not result in an elevation of total serum cholesterol in lean, normocholesterolaemic individuals with a cholesterol intake of less than 300 mg per day. Whe...
Article
Postprandial changes in plasma total cholesterol (TC) are minimal and there is essentially no difference between fasting vs random TC concentrations, as reflected in the small diurnal coefficient of variation (CV) for TC of 2.5%. Similarly, a cholesterol-rich meal within the last 24 hours lacked an impact on plasma TC. Thus, random specimens are ac...

To compare the effects of dietary palmitic acid (16:0) vs oleic acid (18:1) on serum lipids, lipoproteins, and plasma eicosanoids, 33 normocholesterolemic subjects (20 males, 13 females; ages 22-41 years) were challenged with a coconut oil-rich diet for 4 weeks. Subsequently they were assigned to either a palm olein-rich or olive oil-rich diet foll...

Full-text available
The effects on serum lipids of diets prepared with palm olein, corn oil, and coconut oil supplying approximately 75% of the fat calories were compared in three matched groups of healthy volunteers (61 males, 22 females, aged 20-34 y). Group I received a coconut-palm-coconut dietary sequence; group II, coconut-corn-coconut; and group III, coconut oi...
Article
The nutritional status of 96 pre-school children and 61 women of child-bearing age in 3 poor and remote villages in the Bengkoka Peninsula Sabah East Malaysia has been examined by a combination of anthropometric biochemcial and food consumption techniques. 32% of the children were found to be stunted whereas 4% were wasted and 1% was both stunted a...
Article
Serum vitamin A levels were determined for a Malay and an Indian community in rural Malaysia. Thirty two percent of the preschool children of both communities had serum vitamin A levels that may be regarded as 'at risk', namely levels below 20 μg/dl, while 16% and 27% of the Malay and Indian school children respectively were found to be in a simila...
