Alcohol
Some people think of this as a stimulant, but overindulging is not only hard on your liver, it can put you in a bad mood as well. If you already have a tendency to suffer from bouts of depression or have other psychological disorders, alcohol consumption is not recommended.
Deep fried starches
French fries and donuts fall into this category. Before they even hit the frying machine, they are simple sugars and they have very little nutritional value.
Canned and pre-packaged hydrated food
This category of food tends to be packed with sodium and sugar, which can drag you down.
Chocolates
While the caffeine may initially give you a high, the rest of the chocolate, including the sugar, is known as a big depression trigger.
High fat dairy products
In most cases high fat, including dairy, means low nutrient deficiency. Studies in both the Unites States and Europe have shown that nutrient deficiency can lead to depression.
Processed meat
This tends to have a lot of sodium, oil and sugar added.
Refined grains
Most refined grains, such as white rice, pasta and bread are nutritionally imbalanced, starchy, enriched with synthetic vitamins, devoid of fiber and often have added chemicals.
Tea and Coffee
Like chocolate, it is the caffeine that can trigger the depression.
Fast Food
Hamburgers, hotdogs and pizza all contain high amounts of sodium and fat. A lot of the sauces and condiments, such as ketchup, have large amounts of sugar in them as well.
Researchers at the University of Las Palmas de Gran Canaria in Spain and the University of Granada concluded that depression is 51 percent more likely to occur in people who consume large amounts of fast food. They also included junk food like donuts and other deep fried items in their study. The research team also indicated that people who eat fast food on a regular basis tend to have other unhealthy habits, such as sedentary behavior, which are linked to a higher risk of depression.
