Food is a national pastime.
CNN Travel names chicken rice, char kway teow, wantan mee, chai tow kuay, and chill crab as the top 5 foods locals can’t live without (surprisingly, katong laksa didn’t make it to the top 5; it’s listed at #14). According to a 2012 Mastercard survey, locals spend as much as $262 in US dollars dining out each month. There are more local food blogs than supermarkets and more than just a few food apps (e.g., Hungrygowhere, Burpple, Picky). With almost every other person a foodie, that’s quite a lot for a place less than half the size of Greater London and nearly double in its population density.
It’s not the problem of junk food here. Rather, if the National Nutrition Survey in 2010 is anything to go by, nearly half the nation dines out at their local friendly hawker centre more than four times a week (up from 40% in 2004: National Nutrition Survey by HPB). In addition to the problem of too much salt from eating out, which increases the risk of high blood pressure and vascular illness, the most recent data reveal a disturbing trend of overeating. As many as 6 in 10 locals consume too many calories, leaving them vulnerable to the risk of obesity and diabetes, and heart disease.
But there’s a bit more to the story than that. In reality, stress has a bit of a starring role, while sugar plays a vital supporting role.
We typically respond to a stressful situation at work with cortisol (since we can neither fight our co-workers nor flee from our emails, much as we try to sometimes), which encourages our appetite and desire for high energy foods — simple carbohydrates (find the science explained here, here and here). We often think of these as just sugar and honey. But in reality, they often wear clever disguises from white rice, breads, cake, muffins, cupcakes, doughnuts, and biscuits, to hot and cold desserts. And an overconsumption of these lovely, fragrant, heart-warming energy-dense foods increases the risk of impaired insulin function (read this to understand the link between overeating and diabetes).
And while prolonged exposure to stress leads to chronic inflammation, it should be recognized that sugar also contributes to inflammation. In fact, it is sugar in all its various nefarious disguises which is responsible for populating the blood stream with small, dense LDL cholesterol particles. And it’s these small, dense LDL particles which raise our risk of coronary heart disease (read this for a full review of the factors for cardiovascular disease).
