The Heart as The Center of Bodily Vitality
<div style=”padding-top:0px;padding-bottom:0px;margin-top:0px;margin-bottom:35px;” data-rss-type=”text”> n <p style=”margin:0px;”> n n In the fourth century B.C., the ancient Greek philosopher Aristotle described the heart as the most important organ and the center of vitality in the body. His belief that the heart possessed intelligence and controlled body movement formed the ‘cardiocentric hypothesis’ (1).n n </p> n</div> n<div style=”padding-top:0px;padding-bottom:0px;margin-top:0px;margin-bottom:35px;” data-rss-type=”text”> n <p style=”margin:0px;”> n n Unsurprisingly, however, this hypothesis has been long debunked by modern science. Nevertheless, the heart does possess some amazing properties. For example, the heart contains pacemaker cells that generate electrical currents that cause the heart’s automatic contractions. Your heart contracts, or “beats,” approximately 100,000 times each day!n n </p> n</div> n<div style=”padding-top:0px;padding-bottom:0px;margin-top:0px;margin-bottom:35px;” data-rss-type=”text”> n <p style=”margin:0px;”> n n This hard-working is about the size of a fist and must pump blood throughout your body by a complex network of blood vessels. Keeping the heart healthy is critical in delivering oxygen and nutrients to every cell in your body while also removing metabolic waste and carbon dioxide.n n </p> n</div> n<h4 style=”padding-top:0px;padding-bottom:0px;margin-top:0px;margin-bottom:35px; margin-block-start:1em; margin-block-end:1em;”> n n n What constitutes “healthy functioning” of the heart?nn n</h4> n<h5 style=”padding-top:0px;padding-bottom:0px;margin-top:0px;margin-bottom:35px; margin-block-start:1em; margin-block-end:1em;”> n n n Supporting Healthy Blood flownn n</h5> n<div style=”padding-top:0px;padding-bottom:0px;margin-top:0px;margin-bottom:35px;” data-rss-type=”text”> n <p style=”margin:0px;”> n n Like all the other cells in the body that receive oxygen and nutrients, heart cells require the same. Therefore, efficient circulation in the arteries around the heart (the coronary arteries) is critical. Certain dietary components, such as nitrate-rich vegetables, are beneficial in maintaining that healthy blood flow.n n </p> n</div> n<div style=”padding-top:0px;padding-bottom:0px;margin-top:0px;margin-bottom:35px;” data-rss-type=”text”> n <p style=”margin:0px;”> n n Unlike other nitrate-rich foods, such as processed meats, nitrates from vegetables have a beneficial impact on circulatory health (2-4). When nitrates are absorbed, the body converts them to nitrites, which may be converted into nitric oxide under certain circumstances. Nitric oxide can support blood flow by causing vasodilation of the arteries (5).n n </p> n</div> n<div style=”padding-top:0px;padding-bottom:0px;margin-top:0px;margin-bottom:35px;” data-rss-type=”text”> n <p style=”margin:0px;”> n n In addition to their antioxidants and polyphenols, dietary nitrates may be one of the key “heart-healthy” components contributing to the benefits of eating vegetables (especially the green leafy kind such as arugula, kale, and spinach) (2,3).n n </p> n</div> n<h5 style=”padding-top:0px;padding-bottom:0px;margin-top:0px;margin-bottom:35px; margin-block-start:1em; margin-block-end:1em;”> n n n Maintaining Healthy Cholesterol Levelsnn n</h5> n<div style=”padding-top:0px;padding-bottom:0px;margin-top:0px;margin-bottom:35px;” data-rss-type=”text”> n <p style=”margin:0px;”> n n Cholesterol is essential for life as it is critical for maintaining cellular structures and as a precursor for producing sex hormones and vitamin D. While some cholesterol is good, having more cholesterol in your body than it can use may ultimately impair cardiovascular health (6).n n </p> n</div> n<div style=”padding-top:0px;padding-bottom:0px;margin-top:0px;margin-bottom:35px;” data-rss-type=”text”> n <p style=”margin:0px;”> n n Genetics plays a significant role, but lifestyle factors such as your diet and physical activity strongly influence cholesterol levels in the body. These lifestyle factors can help you manage cholesterol levels and help to keep your heart healthy (7). One dietary approach to control cholesterol levels is to consume plant sterols. These compounds help lower blood cholesterol levels by reducing the amount of dietary cholesterol that your body can absorb from foods and helping you eliminate more cholesterol (8).n n </p> n</div> n<h5 style=”padding-top:0px;padding-bottom:0px;margin-top:0px;margin-bottom:35px; margin-block-start:1em; margin-block-end:1em;”> n n n Management of Oxidative Stressnn n</h5> n<div style=”padding-top:0px;padding-bottom:0px;margin-top:0px;margin-bottom:35px;” data-rss-type=”text”> n <p style=”margin:0px;”> n n The heart requires a tremendous amount of oxygen to work continuously. Through a process known as aerobic metabolism, oxygen is used in specialized components of the heart cells called mitochondria to generate energy for the heart (and hence, the whole body).n n </p> n</div> n<div style=”padding-top:0px;padding-bottom:0px;margin-top:0px;margin-bottom:35px;” data-rss-type=”text”> n <p style=”margin:0px;”> n n Unfortunately, this metabolic process – while necessary for life – comes with a “downside”; which is, the generation of reactive oxygen species. Under normal and healthy physiological conditions, the body can efficiently detoxify these species. However, if left unchecked, these metabolic byproducts can increase oxidative stress, damaging cellular structures of the heart (9). In addition, as we age, we are less equipped to handle this oxidative stress. Maintaining a healthy lifestyle with plenty of exercise and healthy nutritional choices can help prevent the harmful effects of oxidative stress.n n </p> n</div> n<h4 style=”padding-top:0px;padding-bottom:0px;margin-top:0px;margin-bottom:35px; margin-block-start:1em; margin-block-end:1em;”> n n n ‘Cardiocentric’ Nutritionnn n</h4> n<div style=”padding-top:0px;padding-bottom:0px;margin-top:0px;margin-bottom:35px;” data-rss-type=”text”> n <p style=”margin:0px;”> n n Aristotle may have been wrong about what the heart can do, but he wasn’t wrong about its central importance in keeping us healthy. We’d like to return the favor and take a ‘Cardiocentric’ mindset regarding nutrition and nutritional support.n n </p> n</div> n<div style=”padding-top:0px;padding-bottom:0px;margin-top:0px;margin-bottom:35px;” data-rss-type=”text”> n <p style=”margin:0px;”> n <em> n n n n n *Foods containing at least 0.65 g per serving of plant sterol esters, eaten twice a day with meals for a total daily intake of at least 1.3 g, as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease.
