Healthy ageing: the natural consequences of good nutrition-a conference report.

Many countries are witnessing a marked increase in longevity and with this increased lifespan and the desire for healthy ageing, many, however, suffer from the opposite including mental and physical deterioration, lost productivity and quality of life, and increased medical costs. While adequate nutrition is fundamental for good health, it remains unclear what impact various dietary interventions may have on prolonging good quality of life. Studies which span age, geography and income all suggest that access to quality foods, host immunity and response to inflammation/infections, impaired senses (i.e., sight, taste, smell) or mobility are all factors which can limit intake or increase the body's need for specific micronutrients. New clinical studies of healthy ageing are needed and quantitative biomarkers are an essential component, particularly tools which can measure improvements in physiological integrity throughout life, thought to be a primary contributor to a long and productive life (a healthy "lifespan"). A framework for progress has recently been proposed in a WHO report which takes a broad, person-centered focus on healthy ageing, emphasizing the need to better understand an individual's intrinsic capacity, their functional abilities at various life stages, and the impact by mental, and physical health, and the environments they inhabit.

The influence of ethnicity on use of herbal remedies in elderly Hispanics and non-Hispanic whites.

OBJECTIVE: To compare the use of herbal remedies between elderly, self-identified Hispanics and non-Hispanic whites (NHW). DESIGN: Cross-sectional, interviewer-administered survey. PATIENTS/SETTING: 186 patients, 65 years and older, at a university-based, ambulatory, senior health center. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Differences in herbal use patterns between Hispanic and NHW participants. Main outcome measures were participants' use of herbal remedies, types of remedies used, medical reason for use, age, sex, Hispanic or NHW ethnicity, income, and education. RESULTS: Overall, 61% of patients had used an herbal remedy at some time in their lives. A larger proportion of Hispanic subjects used herbal remedies than did NHW subjects (77% versus 47%, respectively). Hispanic subjects preferred to use the raw herb in a tea, whereas NHW subjects preferred processed herbs in a capsule or tablet form. Significantly more Hispanic subjects grew or gathered their own herbs and received their information about herbs from a family member than did NHW subjects. Few subjects in either ethnic group received their information about herbal remedies from an allopathic provider. For both groups, the herbs most often used were yerba buena, manzanilla, poleo, osha, and alhucema. The top perceived medical problems that herbs were used for were health care maintenance, dyspepsia, upper respiratory infection, skin problems, and anxiety/nerves/insomnia. CONCLUSION: Ethnicity was related to the frequency of herbal use, the choice and preferred form of herb, and the source of knowledge of herbal remedies. Hispanic culture may account for the observed differences.
