Macronutrient Intake and Obesity
James W. Daily Ⅲ,Youn-Soo Cha 한국식품영양과학회 2000 Preventive Nutrition and Food Science Vol.5 No.1
Obesity is a global pandemic that is increasing throughout most of the world. Increases in obesity are not restricted to highly industrialized countries, but have been observed in newly developed and developing countries as well. Obesity is associated with increased risk for non-insulin dependent diabetes mellitus, coronary artery disease, and some types of cancer. Tragically, eliminating food shortages in developing countries may result in substituting heart disease, diabetes, and cancer for malnutrition. There are many approaches to reducing obesity, including dietary modification, surgical interventions, and drug therapies. However, only dietary modification has the potential to be effective on a global scale. Public health measures in the United States have sought to reduce obesity by reducing the intake of dietary fat. While these efforts have succeeded in reducing dietary fat, obesity has continued to increase, suggesting that moderate fat reduction may not be effective. Other proposed diets include low-carbohydrate diets, low glycemic index diets, and very low fat diets. While all of these diets may be effective for some people, they are not satisfactory for public health policy. In fact, the ratio of fat to carbohydrate may not be as important as previously believed. Humans may be well suited to adapt to diets as varied as a high carbohydrate tropical diet consisting mostly of fruits to the high fat Eskimo diet consisting largely of animal foods. Either extreme may be healthful if providing adequate, but not excessive, energy and adequate amounts of micronutrients. Public health measures may need to focus on reducing the overconsumption of inexpensive and convenient foods.

Feeding and Healing the Family of Man - the Role of Nutritional Supplements
James W. Daily Ⅲ 한국식품영양과학회 2004 한국식품영양과학회 학술대회발표집 Vol.55 No.-
The Family of Man was a 1955 photographic exhibition that depicted normal people in all walks of life from around the world. The viewer was visually confronted with the similarity of all people. The people of the world are now facing common health challenges as a result of changing lifestyles and increasing healthcare costs. Dietary supplements have the potential to be part of the solution. Dietary supplementation with antioxidant vitamins may be the most effective intervention for preventing the onset of Alzheimer’s disease in the rapidly expanding elderly population-and at a very low cost. AIDS is devastating much of the developing world, where few resources are available to treat it victims. Inexpensive multivitamin supplements have been demonstrated to slow the progression of AIDS, reduce the death rate, reduce AIDSrelated morbidity, improve T cell counts, and reduce viral loads. Careful economic analysis demonstrate that calcium and folic acid supplementation could reduce healthcare costs in the USA by $13.9 billion and $1.3 billion, respectively. Most supplements with therapeutic potential have not been subjected to sufficiently rigorous research to permit unqualified public health recommendations. Carefully directed research is needed to identify the supplements with the greatest potential and to verify their safety and efficacy.

Background/Purpose: Few clinical trials have investigated the antidiabetic effects of ginger to date. Several recent clinical trials published in 2013 and 2014, although small, have added contradictory but compelling new evidence about the use of ginger in treating diabetes in humans. Therefore, a systematic review and meta-analysis was conducted to clarify the evidence for using ginger to treat diabetes. Methods: Five randomized clinical trials (RCTs) were identified and included in the meta-analysis. Four of the RCTs were considered high quality and lasted 8 weeks; one lasted only 30 days and was considered low quality. Outcomes measured included fasting blood glucose and insulin, homeostatic model assessment (HOMA)-insulin resistance (IR), and hemoglobin A1c (HbA1c) levels, and were assessed as mean differences in the meta-analysis. Results: Ginger supplementation significantly lowered fasting blood glucose concentrations and HbA1c levels, but did not significantly lower fasting blood insulin or HOMA-IR. Conclusion: Ginger root supplementation significantly lowers blood glucose and HbA1c levels. When combined with dietary and lifestyle interventions it may be an effective intervention for managing Type 2 diabetes mellitus.

Soy isoflavones may benefit some, but not all, menopausal women, and the ability of the women to produce equol may be the major determinant of effectiveness. We assessed the efficacy of soy isoflavones and equol for alleviating menopausal symptoms, especially vasomotor symptoms, in postmenopausal women who were equol producers and nonproducers by using systematic review and meta-analysis of randomized clinical trials (RCTs). We searched 12 English, Korean, and Chinese language scientific and medical databases. We selected all available RCTs that assessed the effect of equol, either equol itself or soy isoflavone in equol producers, on menopausal symptoms in peri- or postmenopausal women. The primary outcome was the effect on hot flashes. The severity of hot flashes was determined by the scores, and sensitivity and risk of bias analyses were conducted. Other outcomes of the review, but not meta-analysis, included depression and adverse events. Six studies (779 total subjects) met all criteria for the systematic review, 5 of those could be included in the meta-analysis (728 total subjects). Two studies included in the meta-analysis reported no statistically significant benefits of equol; the other three did report significant benefits of equol. Meta-analysis revealed a significant benefit of equol for lowering hot flash scores and revealed a generally low risk of bias. In conclusion, this study found that supplementing equol to equol nonproducers significantly lowered the incidence and/or severity of hot flashes in menopausal women.

Although turmeric and its curcumin-enriched extracts have been used for treating arthritis, no systematic review and meta-analysis of randomized clinical trials (RCTs) have been conducted to evaluate the strength of the research. We systemically evaluated all RCTs of turmeric extracts and curcumin for treating arthritis symptoms to elucidate the efficacy of curcuma for alleviating the symptoms of arthritis. Literature searches were conducted using 12 electronic databases, including PubMed, Embase, Cochrane Library, Korean databases, Chinese medical databases, and Indian scientific database. Search terms used were ‘‘turmeric,’’ ‘‘curcuma,’’ ‘‘curcumin,’’ ‘‘arthritis,’’ and ‘‘osteoarthritis.’’ A pain visual analogue score (PVAS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were used for the major outcomes of arthritis. Initial searches yielded 29 articles, of which 8 met specific selection criteria. Three among the included RCTs reported reduction of PVAS (mean difference: -2.04 [-2.85, -1.24]) with turmeric/curcumin in comparison with placebo (P< .00001), whereas metaanalysis of four studies showed a decrease of WOMAC with turmeric/curcumin treatment (mean difference: -15.36 [-26.9, -3.77]; P= .009). Furthermore, there was no significant mean difference in PVAS between turmeric/curcumin and pain medicine in meta-analysis of five studies. Eight RCTs included in the review exhibited low to moderate risk of bias. There was no publication bias in the meta-analysis. In conclusion, these RCTs provide scientific evidence that supports the efficacy of turmeric extract (about 1000mg/day of curcumin) in the treatment of arthritis. However, the total number of RCTs included in the analysis, the total sample size, and the methodological quality of the primary studies were not sufficient to draw definitive conclusions. Thus, more rigorous and larger studies are needed to confirm the therapeutic efficacy of turmeric for arthritis.

Health Benefits of Kimchi (Korean Fermented Vegetables) as a Probiotic Food
박건영,정지강,이영은,James W. Daily III 한국식품영양과학회 2014 Journal of medicinal food Vol.17 No.1
Kimchi is a traditional Korean food manufactured by fermenting vegetables with probiotic lactic acid bacteria (LAB). Many bacteria are involved in the fermentation of kimchi, but LAB become dominant while the putrefactive bacteriaare suppressed during salting of baechu cabbage and the fermentation. The addition of other subingredients and formation of fermentation byproducts of LAB promote the fermentation process of LAB to eventually lead to eradication of putrefactiveand pathogenic bacteria, and also increase the functionalities of kimchi. Accordingly, kimchi can be considered a vegetable probiotic food that contributes health benefits in a similar manner as yogurt as a dairy probiotic food. Further, the major ingredients of kimchi are cruciferous vegetables; and other healthy functional foods such as garlic, ginger, red pepper powder, and so on are added to kimchi as subingredients. As all of these ingredients undergo fermentation by LAB, kimchi is regarded as a source of LAB; and the fermentative byproducts from the functional ingredients significantly boost its functionality. Because kimchi is both tasty and highly functional, it is typically served with steamed rice at every Korean meal. Health functionality of kimchi, based upon our research and that of other, includes anticancer, antiobesity, anticonstipation, colorectal health promotion, probiotic properties, cholesterol reduction, fibrolytic effect, antioxidative and antiaging properties, brain health promotion, immune promotion, and skin health promotion. In this review we describe the method of kimchi manufacture, fermentation, health functionalities of kimchi and the probiotic properties of its LAB.
