Why eating "right" is so important in health

Eating is one of the things we do to live. So, if you think about it the answer comes clear –


When I talk to my patients I like to compare our body to the car. May be it is a silly analogy, but gets the sense of the food importance to everyone. First, we all are made different. And as Toyota cannot be treated in performance or maintenance similar to a Ferrari, so we all cannot be piled up in single-treatment approach without talking about personal differences.

I do not believe any single “healthy” diet provides benefits to everyone. Due to our unique metabolism and body built one can get very sick by following Atkins, Raw or FODDMAP diets. Why? Because we have genetic differences of our gastrointestinal symptom and metabolic demands. Where one person will flourish another will get chronically ill.

Food can cause various problems in the body that are non necessarily allergy. Lets discuss them.

What are digestive enzymes?

Food can cause various problems in the body that are non necessarily allergy. Lets discuss them.

1.Enzyme insufficiency. When any type of food enters the gut multiple enzymes and substances are activated and spilled by glands into the mouth, stomach and intestines. They are meant to break down pieces that you ate into tiny particles absorbed into blood:

  • Proteins break into amino acids
  • Fats break into fatty acids and glycerol
  • Carbohydrates break into simple sugars

The most important glands that aid your digestion are:

Salivary gland. The digestive process starts in your mouth when you chew. Your salivary glands make saliva, a digestive juice, which also has an enzyme that begins to break down starches

Stomach. Glands in your stomach lining make stomach acid and gastric enzymes that break down proteins.

Pancreas. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins:




Liver. Bile is an amazing “juice” that has muliple functions, such as fat emulsifying and breaking down, toxin release from the body. It also colors feces brown. Bile is being stored in a gallbladder and released in small portions between meals (piecemeal release) and as a big portion when you eat.

Intestine. This is a huge digestive factory where enzymes are continuously released by special cells all over intestinal walls to complete the breakdown of proteins, carbohydrates, and fats. Bacteria that lives in your small intestine (probiotics) also breaks down food to feed itself and help you to absorb nutrients.  Imagine that there are billions of bacteria from 120 different varieties working in your gut in symbiosis with your body. The human gastrointestinal (GI) tract contains an abundant and diverse microbial community that gathers more than 100 trillion microorganisms. The density of bacterial cells in the colon has been estimated at 1011 to 1012 per milliliter which makes the colon one of the most densely populated microbial habitats known on earth.
