Food is the best medicine. All your cells, bones, signaling
molecules, and tissues are built from what you eat. For example, dietary
fats are the building blocks of
brain tissue and help
balance hormones, and muscles are built from protein. Different vitamins and
minerals are used to create energy and send
electrical impulses along neurons so that we can move, think, and feel. A nourishing diet is the best strategy against depression.
Many studies have shown that people who eat an anti-inflammatory diet
have significantly lower risks of depression (2-5). A recent study that
tracked about 6,500 women over 12 years showed that women eating an
anti-inflammatory diet had a 20% lower risk of developing depression
than their peers (6). These anti-inflammatory diets consist of
healthy fats,
vitamins and antioxidants, and plenty of
high-quality protein. On the other hand, many foods in the
Standard American Diet (SAD) create chronic inflammation.
These five inflammatory foods are the most frequent offenders I see when treating patients for depression:
Gluten
Dairy
Believe me: I understand that dairy can be deeply pleasurable.
Growing up in an Italian family, many of my fondest memories involve
cheese, ice cream, ricotta, and yogurt. Science supports our attachment
to dairy. On a molecular level, dairy contains morphine-like compounds
which engage our opiate receptors and create mild dairy addiction (11).
If you’re suffering from symptoms of depression or anxiety, it’s worth
eliminating dairy
for 30 days and seeing how you feel. Some people are able to
re-introduce dairy after a month off with no problems, while others
totally lose their taste for it and even vomit when trying it again!
GMOs
In addition to Roundup, the primary herbicide sprayed on GMOs like soy, GMOs also carry a variety of other toxicants
that may be even more harmful in combination than alone.
As even non-GMO foods can be contaminated with pesticides, I advise my
clients, especially those suffering from depression, to
eat organic.
Sugar and Artificial Sugar
Americans love sugar. The average American eats a staggering 164
pounds of sugar per year (12,13). Think about that for a moment. Even
worse,
sugar is highly addictive – the more we eat, the more we want.
Our bodies were not designed to handle the blood sugar and insulin
roller coaster that many of us are on. Here’s how it goes: when you eat
sugar, whether it’s in an obvious form like soda or a non-obvious form
like pasta, your blood sugar increases quickly. This fast increase then
spikes insulin. When insulin removes blood sugar, you then have a blood
sugar crash, and cortisol comes in to compensate and try to move sugar
out of storage and back into the bloodstream. This process, often called
reactive hypoglycemia, is responsible for carb and sugar cravings
(since your brain needs steady sugar to function), which leads to
anxiety, headaches, irritability, and ultimately depression.
Because of all the research showing how harmful sugar is (15-18),
food manufacturers have gotten creative with its naming. Don’t be fooled
by code names like cane sugar, crystalline fructose, maltodextrin,
high-fructose corn syrup – it’s all sugar.
It’s tempting to swap out sugar for artificial sweeteners. Artificial
sugars, like aspartame and sucralose, are ‘zero calorie’ because they
cannot be digested by the human body. But these chemicals don’t just
pass through your body
with no effect.
Artificial sugars confuse hormones and change your microbiome.
A high-profile scientific article showed that artificial sugar
consumption leads to metabolic syndromes like insulin resistance and
diabetes (19). Choose sweeteners that your body recognizes, like
honey.
Vegetable Oils
The Standard American Diet contains large amounts of unhealthy fats,
mostly in the form of commercial vegetable oils. Many processed foods,
ranging from store-bought cookies to salad dressing, contain these oils.
Vegetable oils include safflower oil, corn oil, sunflower oil, soybean
oil, and canola oil. These oils are considered ‘processed’ because many
high-heat and high-pressure steps, as well as chemical solvents, are
required to create them. Further, many of these oils are made from GMOs.
For example, have you ever seen a canola plant? Canola oil, which has been
touted as “heart healthy,”
is derived from the Canadian rapeseed plant. Recognizing that “rape
oil” was not a good marketing tactic, this invention was given a new
name as a combination of “Canada” and “ola,” which means oil.
Today, it
is genetically modified by Monsanto to withstand saturation with Roundup
herbicide (20, 21).
In short, our bodies do not recognize vegetable oils, especially when
they’re heated and distorted.
Consuming vegetable oils sounds the alarm
of inflammation. Processed vegetable oils have been linked to thyroid dysfunction, cardiovascular diseases (22), nutrient deficiencies, cancer (23), and psychiatric disorders like depression (24, 25).
So what do I eat?!
I recommend that people give themselves 2-4 weeks to kick the sugar,
gluten, and dairy habit. In this time, you can try non-GMO foods and
healthier fats like olive oil and lard. People are amazed by how good
they feel and how quickly their tastes change.
