Hi, it’s Dr. Huntington with a special
edition – Halloween Nutrition Video. That might be the very first
time that the words ‘Halloween’ and ‘nutrition’ have ever appeared in the same
English sentence, so let’s see where it takes us… How about the nutritional
benefit of sugar? Well, as it turns out, there really just isn’t any. In fact, the
less sugar you consume, the better. Even the sugar from fruit does not convey
much of a health benefit – not really. Since your cells can generate energy
from fat, which as it turns out is a cleaner fuel source than sugar. But
in this video, let’s focus on how sugar compromises your immune system. After
consuming sugar, your ability to fight pathogens is instantly crippled. This effect lasts for at least several hours. In fact, a consistently high carb
diet put your immune system in a sort of coma. This happens because sugar
weakens neutrophils, which are the most abundant type of white blood cell that
helps you fight off infections and heal damaged tissue. The inflammatory
nature of sugar also creates a cascade of hormone imbalances. For instance,
insulin is the hormone that maintains your blood sugar level in the proper
range, but if you continuously consume sugar and your body is
continuously pumping out insulin, then what can happen is that your cells can
become insulin resistant – and that’s not good because insulin resistance tends to
get worse and worse as you go and it’s really the road that leads to some of
the most common diseases. But also, insulin resistance can make cells unable
to fight pathogens efficiently. This is why obese individuals tend to have fewer
white blood cells and, of course, a reduced ability to fight infection. In
fact, researchers have shown this relationship in mice. What they did was
they took mice and they engineered insulin-resistant helper
t-cells. These helper t-cells are important immune system cells and
because these immune cells were insulin resistant, the mice couldn’t
fight viruses like the h1n1 flu virus. So the moral the story is,
having too much sugar in your diet leads to insulin resistance – and insulin
resistance leads to lowered immune function. That’s
not the only reason to avoid sugar… Sugar causes inflammation
and inflammation is at the root of just about every chronic disease.
Lastly, sugar decreases friendly gut bacteria – those are involved in white
blood cell development. So there’s a direct link between the health
of your microbiome in your gut (that’s the bacteria) and the strength of your
immune system – and sugar is enemy number one to that balance. So this Halloween,
have fun and limit your sugar.
