Last Update on May 16, 2022 : Published on May 4, 2022

We all need a break from the afternoon slumps, especially when working from home. Those snacks you like to munch on – a smoothie, a protein bar, or oat cookies – seem pretty safe to consume during the afternoon hours.

But, if you often experience a mood dip after consuming those “seemingly safe” snacks then you might be eating foods that decrease serotonin levels.

Yes, it’s true, Foods – the snacks and beverages – you consume during afternoon hours to chase away the slumps can be draining your energy instead. Some food groups can help boost mood and increase serotonin levels, certain food groups can decrease your serotonin levels as well.

Serotonin is a neurotransmitter that can help regulate functions in our bodies and brains. Those include our mood, sleep, memory, cognitive health, and more. Having balanced serotonin can help keep our mood stable and emotions positive.

I guess that’s why serotonin is referred to as one of the feel-good hormones and a natural mood stabilizer.

If you usually feel low on serotonin then the foods you’re consuming can be a reason. Below are the foods that decrease serotonin levels and the foods that boost serotonin levels.

Foods That Decrease Serotonin Levels


Here are the three food groups that decrease serotonin levels in your brain and leave your body (and mind) feeling low.

1.Sugary Nibbles

When you consume sugar snacks and refreshments, it can affect your serotonin production. Highly refined foods, especially those that contain sugar such as carbonated drinks, packaged desserts, candies, breakfast cereals, and more.

When you consume these foods regularly, it can reduce the production of tryptophan – the amino acid needed to produce serotonin – and Vitamin B. Any decrease in the production of these chemicals can decrease serotonin levels.

2.Trans-Fat Rich Foods

Trans fat exists in meat and dairy products but in small quantities, however, when you consume trans-fat-rich food regularly, it can increase your cholesterol levels.

Another reason to avoid trans-fat-rich foods is that they can contribute to the low production of serotonin in your body. Foods with high levels of trans-fat include fried foods, processed potato chips, pizza, packaged desserts, and other fast foods. Even your non-dairy coffee creamer may be rich in trans-fat so take a note of the contents before using it.

3.Processed Foods

Other than foods with high sugar, processed foods can also decrease serotonin levels. Highly processed foods contain ingredients that tend to be higher in calories, fat, and added sugar.

They may also contain flavor enhancers. So the next time you look for packaged, sodium-rich frozen snacks, think twice before. Other processed foods can include chips, cookies, packaged sweet treats, hot dogs, confectionary products, protein bars, ice cream, and more.

Foods That Boost Serotonin Levels


According to experts, tryptophan is needed to produce serotonin. Tryptophan, an amino acid,  is not naturally produced so we need to make sure our diet is made up of food groups that include this amino acid.

Fortunately, certain food can help us with this. Here are foods that boost serotonin levels:

  1. Soy:Foods rich in soy such as tofu can also help boost serotonin levels. Soy-rich foods are a great source of tryptophan and can be good substitutes for calcium for vegans and vegetarians.
  1. Nuts:Want a pick-me-up afternoon snack, try eating nuts and seeds that contain tryptophan. Plus, nuts are also rich in fiber, vitamins, and antioxidants so not only they can increase serotonin levels but can also help lower the risk of heart problems and other diseases.
