The human gut environment known as microbiome is a community of different bacteria that has co-evolved with humans to be beneficial to both humans and bacteria. Researchers agree that a persons unique microbiome is created in the first one thousand days of life, but this can be altered throughout your life.
Ultra-processed food, processed-food and the effect on our gut
What we eat, especially processed foods that contain chemical additives and ultra-processed foods affect our microbiomes and increases our risk of disease. Ultra-processed foods contain substances extracted from food(sugar and starch), or added from food constituents(hydrogenated fats), or made in a laboratory and contains food colouring, flavour enhancers etc...
It is important to know that ultra-processed food such as fast food is manufactured to be extra tasty with the use of additives, and is cost effective to the consumer.
Some examples of processed foods include:
Sugar coated dried fruit
Some examples of ultra-processed foods include:
Sodas and cold drinks
Sugary or savoury packaged snacks
Buns and pastries
Researchers recommend fixing the problem by eating the correct food before trying gut modifying therapies like probiotics or prebiotics to help improve the way we feel.
But how does my gut affect my mood
90% of serotonin receptors are located in your gut, a new field of nutritional psychiatry helps patients understand how gut health and diet can positively or negatively impact your mood. There is anatomical and physiological two way communication between the gut and brain via the vagus nerve. The gut-brain axis offers us a greater understanding of the connection between diet and disease, including depression and anxiety.
When the balance between the good and bad bacteria is disrupted, diseases may occur. Examples of such diseases include: inflammatory bowel disease (IBD), asthma, obesity, metabolic syndrome, diabetes, and cognitive and mood problems. For example, IBD is caused by dysfunction in the interactions between microbes (bacteria), the gut lining, and the immune system.
