Bioavailability is the extent to which the nutrients present in the foods we eat are absorbed and utilized by our bodies. In other words, it doesn't matter how nutritious the food is if our systems can't utilize its benefits. This concept establishes the essential link between nutrient intake and their effects on our bodies.
The importance of bioavailability in health
1.- Efficient Nutrient Absorption: Bioavailability determines whether our body can obtain the essential nutrients it needs to function properly. Even a nutrient-rich diet can be ineffective if nutrients are not absorbed properly.
2. Deficiency Prevention: Low bioavailability can lead to deficiencies in key nutrients, which in turn can trigger a range of health problems, from fatigue to immune disorders.
3. Bone and Muscle Health: Minerals such as calcium and magnesium play a vital role in bone and muscle health. Adequate bioavailability ensures that these nutrients are used to strengthen our bones and muscles.
4. Energy and Brain Function: Nutrients such as B vitamins and omega-3 fatty acids are essential for energy production and brain function. Poor bioavailability can affect concentration and mood.
5. Immune System: The bioavailability of nutrients such as vitamin C and zinc influences the immune system's ability to defend us against disease.
Factors Influencing Bioavailability
-
Chemical Form: Some chemical forms of nutrients are better absorbed than others. For example, chelated minerals are absorbed more efficiently than their inorganic forms.
-
Nutritional Interactions: Some nutrients enhance the absorption of others when consumed together. Vitamin C, for example, increases the absorption of non-heme iron from plant sources.
-
Digestive Health: Gastrointestinal problems can affect the body's ability to absorb nutrients, even if they are present in the diet.
-
Nutritional Status: Deficiencies in certain nutrients can affect the absorption of others. For example, a vitamin D deficiency can reduce calcium absorption.
Improving Bioavailability
-
Dietary Diversity: Eat a variety of foods to ensure you get a wide range of nutrients.
-
Smart Combinations: Learn about food combinations that improve nutrient absorption and incorporate them into your diet.
-
Natural Sources: Prioritize whole foods over supplements to reap the benefits of the compounds found in foods.
-
Health Professionals: Consult with health professionals before making major changes to your diet or supplementation.
Bioavailability is an essential piece in the nutrition and health puzzle. While it can be overlooked, its influence is profound and can determine whether we are getting the most out of the nutrients we ingest. With knowledge and informed choices, we can ensure that the nutrients we consume truly contribute to our overall well-being, making bioavailability the hidden key to a healthy and vibrant life.
Remember that prevention is better than cure
