Foods with a low glycemic index (GI) help control blood glucose levels and are associated with a lower risk of adverse health effects. Sago flour is rich in polyphenols and resistant starch, which correlates with a low GI diet. The study developed Thai layer cakes and butter cakes by replacing high-GI flour with sago flour in proportions of 40% to...

The glycemic index (GI) rates carbohydrate-containing foods by how much they boost blood sugar. High GI foods increase the risk of non-communicable diseases, especially diabetes. The aim of the study was to develop the low and medium GI in ready to eat meal with consumer acceptance. The crossover design was use in this study and fourteen healthy pa...

The present work was aimed to determine the glycaemic index (GI) and glycaemic load (GL) of commonly consumed Thai fruits for the potential risk of chronic diseases. Healthy subjects consumed 25 g available carbohydrate (fruits and glucose) in random order. Eighteen fruits were classified as low GI (26.5 - 54.8%) including jujube, unripe mango, ban...

Paddy processing can affect glycemic index (GI) and bioactive compounds of rice. Therefore, the effects of processing conditions such as germination, parboiling and polishing on total polyphenols, ferulic acid and gamma-aminobutyric acid (GABA) contents of seven landrace varieties from Thailand were investigated. Subsequently, the best rice variety...

Abstract Backgound Obesity and dyslipidemia are major risk factors associated with non-alcoholic fatty liver disease (NAFLD). NAFLD refers to the accumulation of fat in more than 5% of the liver without alcohol consumption. NAFLD is the most common liver disease and is rapidly becoming a global public health problem. Maoberry (Antidesma bunius) is...

Background: Sugar consumption is one of the major risk factor associated with nutritional problem and can lead to many chronic diseases later in life. Commercial snacks (with high sugar) are some of the most food-items consumed by the school-aged children based on the food and nutrition status survey of Thailand. Nevertheless, there is limited data...

Evidences have shown that low glycemic index (LGI) and glycemic load (LGL) of rice exert significant benefits to the population who are at risk to type 2 diabetes. LGI rice could minimize the fluctuation of blood glucose and insulin level. This study was aimed to determine the GI values of four new breeding rice varieties developed by using pseudo-...

Diabetes is a serious health problem. Searching for alternative natural antioxidants is considered important strategy to manage diabetes. This study evaluated the effect of Riceberry bran oil (RBBO) supplementation on oxidative stress and organ histology in streptozotocin-induced diabetic rats fed a high fat (HF) diet. Adult male Sprague-Dawley rat...

Riceberry oil (RBBO) has been described as having a high level of antioxidants and functional properties. The aim of the present study was to determine the effects of RBBO on changes in blood glucose, insulin levels, and GLUT4 transporter as well as lipid profiles in Streptozotocin (STZ) - induced hyperglycemic rats fed a high-fat diet. Seventy mal...

The potential anti-cancer activity of compounds extracted from Riceberry bran was evaluated in human cancer cell lines (Caco-2, MCF-7 and HL-60). Anti-proliferation and BrdU incorporation assays indicated a time–dose dependent effect of dichloromethane (DCM) and methanol (MeOH) extracts, and that HL-60 was the most sensitive cell. DNA fragmentation...

The prevalence of iron-deficiency anemia in Nepal is almost 50% of the whole population. Curry powder is a promising vehicle for fortification due to its use in various meals. To evaluate the bioavailability of different iron fortificants in curry powder and their effects on the qualities of curry powder. The serving size of curry powder was evalua...

Chronic dietary cadmium (Cd) exposure results in kidney dysfunction and decrease in bone mineral density. To determine and compare the bioavailability of Cd from vegetable and animal-based foods. Caco-2 cells were exposed to Cd in boiled pig kidney, ark shell, kale, raw kale, mixed boiled pig kidney with raw kale and CdCl2 after in vitro digestion....

The objective of the present study was to determine sugar and dietary fiber contents in 37 varieties of Thai fruits. Sugars were determined by high-performance liquid chromatography and dietary fiber values were measured by the enzymatic-gravimetric method. The total sugar (sucrose, fructose and glucose) content ranged from 4.5 g/100 g (strawberry)...

A total of 37 varieties of fresh fruits obtained from six representative markets in Bangkok, Thailand, were determined for their beta-carotene, lycopene, and alpha-tocopherol contents using high performance liquid chromatography. Beta-carotene content ranged from undetectable up to 616 μg/100 g of edible portion, lycopene content from undetectable...

Background: Iron-deficiency anemia is the most common nutritional problem in Thailand and many developing countries. One of the most sustainable and cost-effective strategies for combating iron deficiency is fortification of staple foods with iron. Objective: In this study, the feasibility of fortifying instant noodles with different forms of ir...

The effects of simvastatin, an inhibitor of 3-hydroxy-3-methylglutaryl CoA reductase (HMG-CoA reductase), on oxidative stress resistance and the protective effects of coenzyme Q (CoQ) were investigated. When simvastatin was administered orally to mice, the levels of oxidized and reduced CoQ(9) and CoQ(10) in serum, liver, and heart, decreased signi...

Soy sauces are available in different types and grades, which allows them to reach consumers of all socioeconomic groups. Ferric sodium ethylenediaminetetraacetic acid (NaFeEDTA) has been used for iron fortification of soy sauces in some countries, however, its high cost may make it unattractive to policymakers and industry. We evaluated the feasib...

Commercially produced dried broken rice is widely used to prepare complementary foods for Thai infants, and it is both convenient and acceptable to persons from all socioeconomic classes. However, inadequate levels of calcium, iron, thiamine, and folate are common in complementary foods for breastfed infants. We developed dried broken rice fortifie...

Information on selenium content of foods in different countries, particularly among Asian countries, including Thailand, is limited. In this study, the fluorometric method for selenium determination was tested for accuracy and reliability prior to applying for analysis of selenium in various Thai foods. Common food commodities, i.e., cereals, meat,...

Plant foods high in calcium were collected from representative markets in Bangkok. The purpose of this research was to study the bioavailability of calcium in plant sources and the presence of some in situ calcium inhibitory factors. Single composite samples from each market were prepared as commonly consumed and analyzed for in vitro calcium bioav...

Two iodine and seven iron compounds were tested for use in the fortification of pure fish sauce, mixed fish sauce, and salt brine for cooking as a means to combat iodine and iron deficiencies. Ferrous sulfate, sodium iron ethylenediaminetetraacetic acid, ferric ammonium citrate, and ferrous lactate were combined with potassium iodide with no effect...

When estimating the iron bioavailability of a meal, the amount and type of meat consumed should be considered; therefore, animal products commonly consumed in Thailand were analyzed for iron attached to hemoglobin (heme iron) and other iron compounds (nonheme iron). Conventional household cooking methods, i.e., blanch- ing, boiling and steaming, we...
