Over the last 50,000 years, humans have obtained a survival benefit from an ability to store fat through the actions of so-called “thrifty genes”. In the past 200 years, changes in the human diet and lifestyle have outstripped the ability of the genome to adjust to a changing environment and billions of people around the world are now obese as a result.
Although studies show that hunter-gatherers ate some 800 different
varieties of plants, today, in many countries, the average intake
is only about three servings of fruit and vegetables per day, which
fails to provide enough of the naturally occurring antioxidants,
phytochemicals, vitamins and minerals that are essential to good health.
Highly processed foods with refined starches, sugars, fats and oils
often fail to contain the essential nutrients that are found in
nutrient-rich foods such as fruits and vegetables but have many more
calories per bite.
At the same time, labor-saving devices of all kinds and advances in
transportation have made a highly sedentary lifestyle possible over the
last 30 years. A global epidemic of obesity and chronic disease,
which is underestimated if one uses the body mass index (BMI) alone, is
sweeping the globe as industrialization and improved standards of
living are spreading to urban centers.
Certain ethnic groups, including Asians, Asian Indians, Latinos
and Native Americans, are genetically susceptible to metabolic syndrome
– due to the accumulation of visceral fat that results in inflammation
in the absence of marked increases in BMI.
It is estimated that
within the next 10 years, the majority of all heart disease will be
associated with type 2 diabetes, with significant increases in
incidence projected in China, India, Southeast Asia, Mexico and Latin
Potential solutions that emphasize social support networks and
innovative methods of integrating a balanced diet and healthy active
lifestyle, in ways that are personally rewarding based on financial or
social incentives, are urgently needed.
