Digestion Components

Digestion has 3 components to it – quality of food consumed, chewing to mechanically break food down, and enzymatic action to chemically break food down. Digestion takes place in the mouth, stomach, and small intestine. It is important to digest your food small enough so it can be easily absorbed into the body and the cells, tissues, and organs can utilize the nutrients. Weak digestion can lead to leaky gut, dysbiosis, bowel toxicity, and overstimulating your immune system. Over time can lead to digestive symptoms like heartburn, reflux, bloating, distention, gas, constipation, or diarrhea. In more severe cases can lead to diseases like gastroesophageal reflux disease (G.E.R.D.), Crohn’s, irritable bowel syndrome, ulcerative colitis, diverticulitis, small intestinal bacterial overgrowth (SIBO), celiac or food sensitivities to certain foods like gluten or dairy.

Nutrition is a huge component for your overall health. Nutrition has to do with the food you eat that nourishes and strengthens the body. But how does the body get the nutrition? Food must be digested. One big misconception about digestion is that once you put food in your mouth, chew, and swallow it, the food is automatically 100% digested, 100% absorbed into the body, and utilized by your body. If this were 100% true no one would ever be sick.

60 to 70 million people are affected by all digestive diseases. There are several reasons why someone would struggle with weak digestion.

The causes could be any combination of the following:
1. High or prolonged stress or mismanaging their stress
2. High intake of poor quality food – eating dead food
3. Poorly chewing each bite of food
4. Subluxations negatively affecting the vagus nerve and nerves that go to the digestion organs
5. Enzyme deficiencies

Let me walk you through the different components of my Digestion Lecture and Digestion Disorders. If you can understand normal digestion, then when something goes wrong and your body expresses symptoms, you can take the right steps to correct it.

Here are some basic definitions to deepen your understanding.

NUTRITION – the science of food and the processes by which the organism ingests, digests, absorbs, transports, utilizes, and excretes food substances.

Ingestion, digestion, absorption, transportation, utilization, and excretion are separate processes that happen independently of one another. You can see if you eat poor-quality food and have weak digestion, all the other processes downstream will be off. It is a domino effect which is why digestion is paramount for great health.

FOOD – a material consisting of proteins, carbohydrates, fats, and other substances (vitamins, minerals, enzymes) for an organism to sustain growth, repair, and furnish energy for all activity of the organism.
A majority of the food being produced today does not meet the above definition, especially with genetically modified food, bioengineered food, and ultra-processed food. We are consuming food-like substances, chemicals, and toxins that poison the body. And people wonder why they are sick. When the body is taken care of and fed nutritious food that actually feeds the cells, tissue, and organs, imagine what could happen. The body must express health. It is what the body was designed to do.

DIGESTION – the process of breaking down food by mechanical (chewing) and enzymatic
action into substances that can be easily absorbed into the body.

ENZYME – proteins secreted by cells that act as catalysts to induce chemical changes in other substances without undergoing change themselves.

Enzymes are the workers of the body. Only enzymes have the capacity to do work. Carbohydrates, proteins, fats, vitamins, and minerals are the raw materials needed for health, but don’t have any capacity to perform work. Two main systems that are heavily dependent on enzymes are your digestion and immune systems. If we didn’t have any enzymes, we would be alive. We would be a big pile of lifeless compounds.

FOOD ENZYMES – when ingested, enzymes in raw food or supplementary enzymes result in a significant degree of digestion, lowering the drain on the organism’s own enzyme potential.

Taking digestive enzymes can strengthen the digestion system and ease the burden on the rest of the body.

Final thought: A clean diet and strong digestion are paramount for great overall health. Dr. Keith has a lot of patients who eat very clean and exercise regularly but still have health challenges. The question isn’t about their diet and lifestyle but how their body is functioning. You can eat clean and have a healthy lifestyle but if your body can perform the way you want it to, this can still give you health challenges. This is where Dr. Keith comes in. The source of stress on your body hasn’t been identified and your body is existing in a weakened state. Dr. Keith is an expert at finding the source of stress, helping you to minimize it and strengthening the body by supporting normal function. Your body will heal itself with this approach.

Dr. Keith Giaquinto is an expert on digestion and practices in Naperville, IL. If you are suffering from digestion challenges, give him a call to get tested. Dr. Keith utilizes your history, a fasting digestive exam, 24 hour urinalysis and blood work to determine were the imbalances are on your body. Once identified, then he customizes a care plan to strengthen and support normal function which will allow your body to heal. Stop your suffering and call for a free screening now.
