加拿大多伦多作业代写:营养需要

营养不仅是解决肥胖问题的一个关键因素,而且在考虑公共卫生结果时,营养本身也是一个重要的关注领域。据估计,多达三分之一的癌症死亡可能归因于不健康的饮食。除此之外,世界卫生组织授权几乎5%的整体工业化国家营养不良疾病负担,特别是低摄入的水果和蔬菜,和实现一个每天摄入水果和蔬菜中的5个部分被视为仅次于减少吸烟预防癌症。也有5个水果和蔬菜的摄入部分将降低中风的危险和6%的心脏病的风险4%,将有助于其他营养的目标,如减肥或者保持健康的体重,并将大大有助于控制糖尿病和降低血压。在这一领域的研究表明,当实验团体增加了维生素和矿物质摄入通过增加水果和蔬菜的饮食摄入量或者服用膳食补充剂含有孤立的维生素和矿物质,孤立的膳食补充剂并没有显示相同的有利影响水平的增加水果和蔬菜的摄入量,虽然这是一项短期研究,因此这些数据并没有显示额外的膳食补充剂可能产生的长期影响。

Nutrition is not just a key component in tackling obesity, but is in itself a key area of interest when considering public health outcomes. It is estimated that up to a third of deaths from cancer may be attributable to unhealthy diets . In addition to this, the World Health Organisation accredit almost 5% of the overall disease burden in industrialised nations to poor nutrition, specifically to a low intake of fruit and vegetables, and achieving an intake of 5 fruit and vegetables portions per day is viewed as second only to a reduction in smoking when preventing cancer. It is also well documented that an intake of 5 fruit and vegetable portions will reduce the risk of stroke by 6% and the risk of heart disease by 4%, will contribute to other nutritional goals such as weight loss or maintaining a healthy weight, and will contribute significantly to controlling diabetes and lowering blood pressure. Research in this area has shown that when experimental groups increased their vitamin and mineral intake by either increasing their dietary intake of fruit and vegetables or by taking dietary supplements which contained isolated vitamins and minerals, the isolated dietary supplements did not show the same beneficial effects as an increased level of fruit and vegetable intake, although this was a short-term study and therefore this data does not indicate the long-term impact that additional dietary supplements may have.
