What is Althera and its Role in Infant Nutrition?
Althera, developed by Nestlé Health Science, is a hypoallergenic, extensively hydrolyzed whey-based infant formula. It is specifically designed for the dietary management of infants and young children with mild-to-moderate cow's milk protein allergy (CMPA) and/or multiple food protein allergies. This specialized formula provides a nutritionally complete alternative for babies who experience allergic reactions to the intact proteins in standard cow's milk formulas. The key to Althera's function is the extensive hydrolysis of whey protein, breaking it down into smaller, less reactive peptide fragments that are easier for a sensitive digestive system to tolerate. This process helps reduce the likelihood of allergic symptoms while still providing essential nutrients for healthy growth.
The Science Behind Althera: Extensively Hydrolyzed Protein
The effectiveness of Althera stems from its use of extensively hydrolyzed protein. In standard formulas, the large cow's milk protein molecules can trigger an immune response in infants with CMPA. Extensive hydrolysis breaks down these proteins through enzymatic action, significantly reducing their allergenicity and the likelihood of provoking an allergic reaction. This process is typically effective in managing symptoms such as eczema, gastrointestinal issues, and respiratory problems in most infants with mild-to-moderate CMPA.
Key Ingredients in Althera
Althera's formulation includes key ingredients for comprehensive nutrition:
- Extensively Hydrolyzed Whey Protein: The primary protein source, designed to be less allergenic.
- Lactose: The main carbohydrate source, providing energy and mimicking breast milk composition.
- Vegetable Oils: A blend offering necessary fats for development.
- DHA and ARA: LCPUFAs important for brain and eye development.
- Vitamins and Minerals: A complete profile for balanced growth.
- Human Milk Oligosaccharides (HMOs): Found in some versions, aiding immune system development.
Althera vs. Other Hypoallergenic Formulas
Hypoallergenic formulas for CMPA fall into categories like Extensively Hydrolyzed Formulas (eHFs), such as Althera, and Amino Acid Formulas (AAFs). The choice depends on the allergy's severity.
| Feature | Althera (eHF) | Amino Acid Formula (AAF) |
|---|---|---|
| Protein Breakdown | Whey protein extensively hydrolyzed into small peptides. | Proteins broken into individual amino acids. |
| Allergenicity | Very low, for mild-to-moderate CMPA. | Allergen-free, for severe CMPA or multiple allergies. |
| Taste/Palatability | Generally more palatable than casein-based eHFs. | Often has a more distinct taste. |
| Cost | Less expensive than AAFs. | Often more expensive. |
| Indication | First-line option for most CMPA cases. | For severe cases or intolerance to eHFs. |
Proper Use and Medical Supervision
Althera is a food for special medical purposes and requires strict medical supervision from a healthcare professional. They can determine if Althera is appropriate and rule out other conditions. Correct preparation is vital: follow manufacturer instructions, use boiled and cooled water, and feed immediately after preparation to avoid illness or improper nutrition. Monitoring the infant's growth and symptom improvement is necessary to confirm the formula's effectiveness.
Conclusion
What is Althera? It is a crucial nutritional option for infants with CMPA. As an extensively hydrolyzed formula, it effectively manages mild-to-moderate CMPA by reducing the risk of allergic reactions while providing complete nutrition for healthy development. However, it is essential to use Althera under medical supervision and follow preparation guidelines for optimal outcomes. For parents dealing with infant allergies, Althera, guided by professional advice, can be a key step towards their child's well-being. For further information, the official Nestlé Health Science website is a valuable resource.
The Dietary Management of CMPA
Managing CMPA demands a careful approach, and Althera offers a targeted solution. It works by addressing the immune system's reaction to milk proteins by presenting them in a less allergenic form. For many parents, switching to Althera can alleviate symptoms like chronic crying, vomiting, or skin rashes. Successful management allows infants to thrive and feed comfortably. However, Althera has contraindications, emphasizing the necessity of medical advice before use.
