Bioavailability is the extent to which the nutrients present in the foods we eat are absorbed and used by our body. In other words, it doesn't matter how nutritious foods are if our systems can't take advantage of their benefits. This concept establishes the essential link between the intake of nutrients and their effects on our body.
The importance of bioavailability in Health
1.- Efficient Nutrient Absorption: Bioavailability determines whether our body can obtain the essential nutrients to function correctly. Even a nutrient-dense diet can be ineffective if the nutrients are not absorbed properly.
2. Prevention of Deficiencies: Low bioavailability can lead to deficiencies of key nutrients, which in turn can trigger a host 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 ability of the immune system to defend us against diseases.
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 improve 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: Deficiency of 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 apply them to your diet.
-
Natural Sources: Prioritize whole foods instead of supplements to reap the benefits of compounds present in foods.
-
Health Professionals: Consult health professionals before making major changes to your diet or supplementation.
Bioavailability is an essential piece in the nutrition and health puzzle. While it may be overlooked, its influence is profound and can determine whether we are making the most 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, vibrant life.
Remember that prevention is better than cure
