The Alchemy of Nutrition and Environment to Age with Grace and Tranquility

By Michael McBurney

Getting  older is only better than the alternative. Everyone’s goal is to age, surrounded by family and friends, in the best of health until the last day. The chances of the ideal scenario depend upon genetics, environment, nutrition and sometimes luck. The 6 leading risk factors for non-communicable diseases  (NCD) globally are high blood pressure, tobacco smoking (including second-hand smoke), household air pollution, diet low in fruits, alcohol use, and high body-mass index.

To reduce premature mortality from NCD, targets have been set for tobacco and alcohol use, salt intake, obesity, and raised blood pressure and glucose. Using data collected from 16,721 persons living in Switzerland between 1977 and 1993, Martin-Diener and colleagues evaluated the impact of 4 risk factors (smoking status, alcohol consumption, physical activity and diet - measured by ‘no reported fruit consumption’) on mortality over 31 years of follow-up. Living an unhealthy lifestyle significantly increased the risk of dying after 65y of age. Combining 4 risk factors increased all-cause mortality 2.5 fold. The risk was greatest in those over 75y.

The most common triad of conditions in the US is hypertension, hypercholesterolemia and heart disease – all nutrition-related. Economic assessments show that improving nutrient status (omega-3s, B vitamins, dietary fiber, chromium, lutein & zeaxanthin, calcium & vitamin D, and magnesium) can help reduce the risk of nutrition-related health care expenses. Because of low fiber intake, if only 50% of the adult US population increased dietary fiber intake by 3 g/d, the annual medical cost savings would exceed $2 billion. Imagine the reduced strain which could be achieved just by adding fiber!

Those living in the US are fortunate to have good air quality with low levels of particulate matter.  This isn’t always the case (see today’s photo from China). Unfortunately, millions of Americans are deficient in vitamins A, C, D, E, B6, B12, folate, and iron (CDC Report, Fig 1). Untold many more millions have suboptimal nutrient status.

The US spends more than its OECD peers on health-care. Governments can help create environments supportive of long-term health but ultimately the choice is individual. People choose their lifestyle. And live with the consequences of these choices. Poor health may be mitigated by medicines but quality and longevity of life depend upon how we treat our bodies.
