Dietary Supplements of Plant Origin: A Nutrition and Health Approach

This shared decision making pathway informed model is especially important for hysterectomy, where multiple approaches/techniques are available. Clinical pathways are an effective instrument to decrease undesired practice variability, improve clinician performance, and provide consistent therapy for diseases on a global scale.10,17 The pathway systems could become a driver of change in clinical practice in the US and around the world, influencing both the patient and provider side of healthcare. In addition, clinical pathways can serve as a framework for moving forward and increasing the efficiency of care while decreasing the variation in care. appropriate based on clinic flow).

This was traced back to the inhibition of COX2 and, in part, COX1. This finding is surprising and difficult to reconciliate with the PG2-promoting activity of cyanidin.

The molecular mechanism is unknown. In in vitro assays, gossypol is a powerful inhibitor of lactate dehydrogenase, but it is not clear how this translates into the observed antifertility activity. In the 1990s, interest in gossypol was rekindled by the discovery of its antiproliferative effects, selective for cancer cells, and more pronounced for the (⫺) form compared to the racemate (Joseph et al., 1986).

Nonetheless, biotechnology spawns ethical, social, and legal debates at the margins of pharmaceutical bioprospecting, including the collaboration between big business and big science, the ethics of genetic engineering, and the patentability of life forms as well as ideas about genetics and racism, culture, and ethnicity. However, it is significant to note that, since the inauguration of the CBD, no pharmaceutical bioprospecting product developed by using traditional knowledge has generated an economic profit. (But this does not mean that pharmaceutical companies do not try to impede or coopt efforts to get natural plant products to market.) Also, only a small number of bioprospecting research expeditions begin by using ethnobotany as a discovery methodology, with the work soon evolving into economic botany as the laboratory focus shifts to the plant’s chemistry, biological activity, and pharmacology/toxicology. During drug discovery, active chemical components are isolated, often modified, and patented.

However, recent randomized, controlled clinical trials did not provide substantive evidence to support its purported ergogenic effects in healthy subjects. Some evidence is available for treating erectile dysfunction and age-associated memory-impairment with ginseng. It is also an antioxidant and immune stimulant.

The long half-life (c.25 h) means that repeated intake leads to accumulation (Strick et al., 2000). Taken together, these data show that substantial differences between the pharmacokinetics and the metabolism of quercetin (and presumably of other flavonoids as well) exist between humans and experimental animals. Dietary flavonoids and especially quercetin have been associated with a decreased risk of adult malignancies.

This study also showed that rates of alcohol consumption were associated with age, education, geographical area, gender, tobacco smoking, involvement in violence, watching television, computer use and playing computer games, wearing safety helmets and use of health services. Alcohol consumption tended to increase with age for both males and females. Macronutrient and micronutrient deficiencies are very common in the general population and may be even more common in patients with hypertension and cardiovascular disease due to genetic or environmental causes and prescription drug use. These deficiencies will have an enormous impact on present and future cardiovascular health and outcomes, such as hypertension, myocardial infarction, stroke and renal disease, and on overall health costs. The diagnosis and treatment of these nutrient deficiencies can reduce blood pressure; improve vascular health, endothelial dysfunction, and vascular biology; and decrease cardiovascular events.

Information was also obtained concerning leisure activities and use of health care. The paper also sets out to examine possible gender differences in relation to alcohol consumption and risk behaviour and to propose the development and implementation of alcohol monitoring and prevention programs in Vietnam. Alcohol consumption is associated with a wide range of health and social consequences.

Their responses were recorded directly onto the questionnaire. The core questionnaire contained 65 multiple-choice questions.

The German Commission E suggested a daily dose of ginseng as 1-2 g of root per day for up to three months, or 200-600 mg of standardized extracts (4-7 per cent ginsenosides) (Blumenthal et al., 2000; Mahady et al., 2001). Dietary fibre Dietary fibre is composed mainly of non-starch polysaccharides and lignin. Watersoluble forms of dietary fibre includes pectins, beta-glucans, gums and mucilages while the insoluble portion consists of cellulose, lignin and hemicelluloses.

Given the ubiquity of the dietary exposure to flavonoids, it is unclear why infant leukaemia is so rare (less than 40 cases per million newborns). Other causes, like an impaired DNA repair, are probably involved, and ongoing molecular epidemiology studies will hopefully clarify this important matter.

The biochemical measurements findings shows the mean and SD total triglycerides, cholesterol, HDL, LDL and fasting blood sugar were 187.5 ± 76.5, 198.5 ± 42, 39.16 ± 8, 122.3 ± 41.6, and 92.3 ± 39.5 mg/DL, respectively. Strengths of the Study As there are very limited number of studies conducted in the past involving pregnant women of rural India, this study can contribute significantly and provide a glimpse about health conditions of antenatal women in rural population of India. The current study also provided an opportunity to contact study subjects and identify some previously undetected at risk women who were referred for further evaluation and management.

13.3% were mouth snuff users which are almost double of cigarettes smoker. Around 54% of study participants were using solid oil in their kitchen for cooking. As we had data on number of days per week that research participants consumed fruit (average number of fruit servings per day), these data were categorized dichotomous by cut of three days per week. Data shows 65% of participants were consuming fresh fruits less than three days per week as compared to 27% who were consuming fruits more than three days per week. These variables have been described in Table 2.

Last, but not least, most health-promoting activities of food plants are preventive rather than curative. Prevention has always produced less fanfare than the latest medical breakthrough, though transition from therapeutic to preventive medicine is making great strides with the current huge investments for the discovery of ‘high-tech’ cures, with an increased dependence on the wealth of information available from the human genome project. Despite these difficulties and limitations, diet can still be a productive hunting ground for pharmaceutical leads with a definite biological activity, and we have tried to overview the area from a pharmaceutical point of view. Currently, most research in this field is fuelled by the growing dietary supplements industry, but the diet- medicine interface is also rich in opportunities for the pharmaceutical industry. The discussion of the ‘natural’ occurrence of mainstream drugs in food will show how blurred this interface is, and we will next move on to review the basic chemistry and biochemistry of small molecules of dietary origin currently under clinical development, concluding with an overview of a selection of further agents which might soon enter clinical studies.
