This brief review will focus on the effect of exercise on protein requirements. Evidence has accumulated that amino acids are oxidized as substrates during prolonged submaximal exercise. In addition, studies have determined that both endurance and resistance training exercise increase skeletal muscle protein synthesis and breakdown in the post-exercise recovery period. Studies using nitrogen balance have further confirmed that protein requirements for individuals engaged in regular exercise are increased. The current recommended intakes of protein for strength and endurance athletes are 1.6 to 1.7 g/kg and 1.2 to 1.4 g/kg per day, respectively. Presently, most athletes consume an adequate amount of protein in their diet. The timing and nutritional content of the post-exercise meal, although often overlooked, are known to have synergistic effects on protein accretion after exercise. New evidence suggests that individuals engaging in strenuous activity consume a meal rich in amino acids and carbohydrate soon after the exercise bout or training session.","PeriodicalId":83835,"journal":{"name":"Nutrition in clinical care : an official publication of Tufts University","volume":"5 4","pages":"191-6"},"PeriodicalIF":0.0,"publicationDate":"2002-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1046/j.1523-5408.2002.00606.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"22065976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is associated with both overnutrition and undernutrition, but it is not congruent with malnutrition. Food insecurity affects human development and health throughout the lifecycle, but can be particularly harmful during critical or vulnerable stages early and late in life. Understanding the causes and consequences of food insecurity and knowing how to identify them can improve the quality and effectiveness of clinical care, and facilitate prevention and treatment of many kinds of health problems. Numerous public policies and programs exist to ameliorate and prevent poverty-related food insecurity. However, the resources to support them ebb and flow with the politics of annual state and federal budgetary cycles. Support and need for these social-safety-net programs also vary with business cycles. Unfortunately, need often expands as support shrinks along with employment and government revenues during recessions, and shrinks as support expands along with employment and government revenues during expansions.","PeriodicalId":83835,"journal":{"name":"Nutrition in clinical care : an official publication of Tufts University","volume":"5 4","pages":"152-67"},"PeriodicalIF":0.0,"publicationDate":"2002-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1046/j.1523-5408.2002.00505.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"22065970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, low folate status is a suspected risk factor for depression that also results in an increase in circulating levels of the sulfur amino acid homocysteine. Homocysteine has emerged as an independent risk factor for stroke, and recent studies suggest that vascular disease affecting the brain and Alzheimer's disease may result together in senile dementia. The relationship between stroke and AD was at first interpreted as coincidence, given the pathologic distinctions between the two diseases. However, the connection is now hypothesized to reflect some common pathogenic factors involving folate, homocysteine, or both. It remains unclear whether there is a causal relationship between neurological dysfunction in either condition with folate or homocysteine. Nevertheless, since improvement of folate status lowers homocysteine levels, the hypothesis that folate supplementation may lower the risk of several important health consequences of aging, including various forms of neuropsychiatric dysfunction, is worthy of current intensive exploration.","PeriodicalId":83835,"journal":{"name":"Nutrition in clinical care : an official publication of Tufts University","volume":"13 1","pages":"124-32"},"PeriodicalIF":0.0,"publicationDate":"2002-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87339151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such values all increase coronary heart disease (CHD) risk. The National Cholesterol Education Program Adult Treatment Panel III guidelines continue to focus on optimizing LDL-C values (established as < 100 mg/dL or 2.6 mmol/L), especially in those with established CHD, diabetes, or a 10-year CHD risk over 20%. Dietary saturated fat (< 7% of calories) and cholesterol (< 200 mg/day) restriction, and the use of 3-hydroxy-3 methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors are the mainstays of treatment in this regard. Such treatment substantially reduces CHD risk. Severe hypertriglyceridemia (> 1000 mg/dL or 11.0 mmol/L) is associated with pancreatitis, and fat restriction, control of glucose, and fibrate therapy are indicated in such patients. Niacin is currently the most effective agent for lowering Lp(a) and raising HDL-C. Current recommendations for treatment by diet and drugs are outlined.","PeriodicalId":83835,"journal":{"name":"Nutrition in clinical care : an official publication of Tufts University","volume":"2 1","pages":"115-23"},"PeriodicalIF":0.0,"publicationDate":"2002-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89027274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
