The Digestive System: Are You Really What You Eat?

The Digestive System: Are You Really What You Eat?

“You are what you eat.” This age-old adage has passed through generations and shaped our understanding of the connection between diet and health. However, the question remains: Is it true? A closer look at the intricate mechanisms of the digestive system challenges the credibility of this popular expression.

What Is the Digestive System?

Digestion encompasses a series of events aimed at breaking down intricate nutrients into forms that the body can readily utilize. This complex and crucial process begins as soon as food enters the mouth. From the enzymes present in saliva to the acidic conditions of the stomach, each stage of digestion plays a vital role in extracting essential nutrients from everything we consume.

The digestive system contains the gastrointestinal tract, liver, pancreas, and gallbladder. According to the National Institutes of Health (NIH), “The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.”

Factors Influencing the Digestive Process

Our nervous systems, hormones, bacteria, blood, and digestive organs collectively process the foods and liquids consumed daily. Perhaps even more crucial than the intake of substances is the body’s capacity to absorb and utilize them effectively. Thus, the reality is far more complicated than the oversimplified notion that your daily meals directly define you and your health.

The body is intentional and selective, absorbing vitamins, minerals, and nutrients while expelling waste. This deliberate process allows only elements beneficial to the construction of your cells, tissues, and organs to remain in your system.

Where Is the Digestive System?

The gastrointestinal tract comprises a sequence of hollow organs interconnected in a lengthy, winding tube extending from the oral cavity to the rectum. During the swallowing process, the tongue propels the food into the throat. A protective flap of tissue known as the epiglottis covers the windpipe, preventing choking and allowing nutrients into the esophagus.

The lower esophageal sphincter, a circular muscle at the end of the esophagus, then relaxes to allow food into the stomach. This ring remains closed to prevent stomach contents from refluxing into your esophagus. The muscles in the stomach effectively blend the food and liquids with digestive enzymes to form chyme. These contents are subsequently released into the small intestine.

Next Steps in Digestion

The pancreas produces a fluid containing enzymes to facilitate the absorption of carbohydrates, fats, and proteins. Bile, a fluid crucial for the digestion of fats and certain vitamins, forms in the liver. These essential liquids are transported to the small intestine for utilization and the gallbladder for preservation via narrow tubes known as ducts.

Small intestine walls also use digestive fluids, absorbing water and nutrients into the bloodstream. The waste products then flow to the large intestine, which absorbs water to transform the waste into stool. At the bottom of the large intestine, the rectum stores stool until expelling it through the anus when a bowel movement occurs.

What Powers the Digestive System?

Coordination of the digestive process involves a collaborative effort between hormones and nerves. Communication occurs within your gastrointestinal tract and in a reciprocal relationship between the GI tract and the brain.

The cells along the small intestine and stomach lining produce and discharge hormones. These crucial chemical messengers instruct the body on when to produce digestive juices and signal to your brain whether you are hungry or full. Additionally, the pancreas produces essential hormones that are vital to the digestive process.

The Nervous System’s Role in Digestion

Additionally, nerves link the central nervous system to the digestive system. The enteric nervous system produces messages when the GI walls stretch. These various substances accelerate or hinder digestive juice production and nutrient distribution.

For instance, the sight or aroma of food creates a cognitive signal to trigger salivation, “which is necessary for the moistening of food products, breakdown of carbohydrates by salivary amylase (formerly known as ptyalin), antimicrobial, and other protective mechanisms.”

Are You What You Eat?

The notion that “You are what you eat” transcends a mere cliché when examined within the context of the complex digestive process. Instead of a straightforward formula, digestion unfolds as a dynamic interaction between intake and implementation. Embracing this intricacy paves the way for informed dietary choices.

The truth is, “You are what your body keeps of what you eat.” Although everyone’s body digests things in the same manner, your body will have a unique way of absorbing and processing nutrients and waste. Nature does most of the work, but you can enhance your digestive processes to retain more nutrients and be intentional about your food choices.

I had a catastrophic event requiring a long hospital stay and at discharge my HMO offered Lifespring meal services. Initially, I was offered a puree diet and then as I improved a regular diet. Staff were kind, patient, and their supervisor, Christina was extremely accommodating. This is an amazing company who goes the extra mile to ensure patients receive their meals promptly. The food is delicious with a variety of meals. I would highly recommend Lifespring.

I've been receiving Lifespring meals for the past several years. I find them to be fresh, convenient, and delicious! The meals are both balanced and nutritious, and, because they are prepared fresh, and then flash frozen; all one needs is a microwave! Delivery is prompt and courteous, and if ever you want to make a change, the friendly office staff is available by phone. Thank you, Lifespring! 🤗😘
