You Are What You Absorb: Factors That Influence Bioavailability Of Nutrients

A healthy diet is an essential aspect of every individual’s daily routine to a healthy lifestyle. As what a famous line is saying, “You are what you eat” means that whatever you may be feeling, it depends upon the sort of food you are consuming. Thus, eating the right kinds can make you feel healthy and fit.

Overtly seen today, people are involved actively in programs and classes with dedication and discipline working out to maintain the desired body shape, as well as the look of becoming fit. While keeping up with all the exercises, one cannot achieve the muscled body without balancing their food intake.

Relating to a balanced diet, one must be mindful about the nutrients of the food consumed; the calories, vitamins & minerals, carbohydrates, protein, etc. To better savor the results of these substances, the body must first absorb these and will further add compelling effects to a person’s body. Thus, it is not just about the food you are eating, but also the nutrients you are absorbing that can affect an individual’s body.

Moreover, there are also individuals in which bioavailability of nutrients are not possible or difficult to happen. There are various factors of why these people experience the malabsorption of nutrients, and one of them is due to digestion problems.

Lactose Intolerance and Malabsorption

Affecting 75% of the world’s population, a lot of people experience problems in the digestive system upon eating dairy products. As a manner to prevent gastrointestinal symptoms such as bloating, diarrhea, nausea, that often come along with eating dairy foods,  several individuals choose to avoid consuming milk entirely.

Above mentioned are the symptoms of lactose malabsorption wherein all the lactose you eat or drink cannot be digested and broken down by your small intestine.

The main reason that some individuals are unable to digest dairy products is that they fail to have the lactase enzyme to break down lactose that becomes glucose and galactose; both are called simple sugars that usually converted in the liver. Thus, a powerful nutrient that provides energy to the body.

Moreover, onset typically occurs in late infancy or early adulthood. According to a survey, across all ethnic groups, lactose intolerance and malabsorption prevalence are varying. As mentioned in the dairy nutrition website, this type of digestive problem is most common among African Americans, Asian Americans, and Hispanic Americans. Thus, the least common in European Americans.

Crohn’s Disease

Typically, the foods we ate are broken down in the stomach and absorbed in the small intestine, but for individuals with this type of disease, the nutrients cannot be absorbed correctly by the small intestine, leading to malabsorption.

Some individuals experience Crohn’s disease, which creates inflammation in some part of your digestive tract and can affect any portion of it, most often of which it affects your colon and small intestine.

This type of disease is also a part of the inflammatory bowel diseases, and it causes severe diarrhea, abdominal pain,  weight loss, and malnutrition. Research has shown data that further than 1.7 million grown-ups in the United States had IBD and about 565,000 of which had Crohn’s disease.

Prevalence of the disease is more evident in women than in men in terms of sex. Studies have found that Crohn’s disease in the United States and other parts of the globe become more prevalent over time, and it is more likely to emerge in people who smoke cigarettes, aged 20 to 29 years old, and who have a family member with IBD.

Whipple’s Disease

Another disease that targets the small intestine is the Whipple’s disease; an infection caused by Tropheryma whipplei bacteria that can affect the digestive system and can further create problems elsewhere in your body, including the joints, eyes, lungs, heart, and your immune system.

It is a rare disease that less than one in every one million individuals get this disease yearly and typically stops small intestine from breaking down nutrients from passing into the body. Thus, joint pain is an early symptom and can include weight loss, abdominal pain, diarrhea, memory loss, and mental changes.

Scientist discovered that the bacteria causing the Whipple’s disease are most common in sewage wastewater and soil. Furthermore, the condition seems to be more prevalent in farmers and other individuals who are working outdoors and has constant contact with the ground.

Given the fact that nutrient absorption is crucial to every bodily function, we should enhance our ways of doing things that can somehow boost the bioavailability of these nutrients.

One of these ways is through taking supplements. Most individuals need this to increase the absorption of nutrients, most especially bodybuilders who need to intensify their immune system. While there are many available worldwide, pick those that have more powerful nutrients, and are supplementing for men and women effectively and efficiently.

Dietary fiber is the primary source of prebiotics, and people need this every day, most notably all bodybuilders. This source happens naturally in vegetables and fruits, including garlic, oatmeal, leeks, and bananas, but you necessarily need to eat large amounts of these foods for you to experience its health benefits. Thus, supplements that contain these sources can be taken to help in multiplying good bacteria in your stomach and increase their growth.

Great benefits of prebiotics include better gut health, enhancing your digestion, elevating immune system, lower risk for diseases, and micronutrient deficiencies.

Your body needs good bacteria and yeast, especially your digestive system. They are called good bacteria for the fact that it helps your gut stay healthy. Probiotics work as the one responsible for balancing between the opposing good and harmful bacteria so that the body can work well. Thus, probiotics can also replace the number of good bacteria lost after you took antibiotics.

Moreover, probiotics are also available as supplements. They somehow help you with your gut movement while treating inflammatory bowel diseases, diarrhea, and bowel syndrome.

Digestive Enzymes

Proteins are essential to every individual’s system. Digestive enzymes are a body-made protein that guides the breaking down of food into smaller particles to better absorb it by your body.

Lipase enzyme breaks down fats, proteases, and peptidases for protein break downs, and amylase enzymes are responsible for the breaking down of carbohydrates. All of these work together to better give a healthy digestive tract and immune system to your body.

Furthermore, digestive enzymes are also available today as supplements to better aid people with the specific nutrients needed by the body. Thus, these supplements help solve everything from heartburn to a healthy gut.

The risk of diseases and wellbeing can enhance if people absorb enough nutrients needed by the body. Thus, bodybuilders and all of the individuals desire the necessary dosage of nutrients absorption every day to help fight back to autoimmune diseases and to have the appropriate strength required by the body.
