Good nutrition is the foundation of good health. Food can be used as medicine because the true purpose of food is to provide information to the body so that it can function in the way it is designed to function. Food as medicine is the most trending approach in healthcare field; however, it is not a new concept. One of the most famous quotes by Hippocrates around 400 B.C. “Let food be thy medicine and medicine be thy food” was an inspiration to current food as medicine movement. Many ancient medicine fields including Ayurveda and Chinese medicine has focused on using food as medicine for thousands of years. Using household remedies for healing common health issues is a common practice in many parts of world.

Chronic inflammation is at the root of many chronic diseases. Poor diet, stress and gut permeability plays a role in chronic inflammation. Our modern-day diet is a big culprit in increased incidence of inflammation and chronic diseases. Standard American diet (SAD) is severely lacking in nutrients and loaded with processed foods, sugars, artificial colors and additives. An average American eats ~ 22 teaspoons of sugar/ day. We have become a nation that is malnourished, inflamed, and sick, over-fueled with foods that lack the essential information humans need to function properly.

It is time we focus on changing the fuel we are providing to our bodies. Eating healthier diet rich in phytonutrients, anti-oxidants, fiber and good quality fats can help in reducing inflammation, maintain stable blood sugar levels and boost our immune system. As we know ~ 70% of our immune system is in the gut – what we eat becomes extremely important to support our immune function.

Our microbiome (the gut bacteria) plays a very important role in our health. What we eat affects our microbiome; which can either increase or dampen the inflammation in body. Eating a plant rich diet with minimal processed foods can feed the healthy bacteria in our gut and hence provide protection against chronic diseases.

A healthy diet plays a role on how we express our genes. Nutrigenomics is a science of focusing on how nutrition impacts our genes. A balanced diet can have a protective effect on genes by turning them on and off. Food provides information to the entire body and mind; it is a biochemical messenger to our entire system. What we eat can impact on sending positive messages to our genes.

The quality of food plays as important role as quantity. The use of pesticides, hormones and chemicals as well genetically modified foods has increased significantly in the last 20 years. Many of these chemicals are inflammatory in nature and are endocrine disruptors which can create an imbalance in body systems; hence, it is extremely important to pay attention to how we grow, produce and prepare our foods.

Growing research supports that the type of food we eat is not only important for our physical health but can influence our mental health and mood.  Fresh fruits and vegetables are rich in brain, neurotransmitter and mood protective compounds like antioxidants and phytochemicals. Omega 3 fats are the building blocks of happy neurotransmitters. Hence, a balanced diet rich in vegetables, fruits, healthy fats is extremely important for better mental health.

Food nourishes our body, mind and soul. In addition to focusing on what we are eating; it is also important to pay attention to how and when we eat our meals and how we prepare our meals. It is important to understand your bio-individuality. We all are unique in our body needs, food preferences and cultures. It is important to make small changes gradually as it can help make a long-lasting health benefit.
