Is it good to take oat milk every day? Benefits and side effects explained

4 min read

Oat milk has exploded in popularity, with one in four coffees from major chains in the UK being made with a plant-based alternative. As a creamy, dairy-free substitute, it has become a daily staple for many, but is it good to take oat milk every day? The answer depends on several factors, including the specific brand and your individual health needs.

Quick Summary

This guide provides a comprehensive overview of the benefits and potential drawbacks of daily oat milk consumption. It details its nutritional profile, heart and bone health advantages, and digestive benefits, while also examining common concerns like sugar content, digestive issues, and nutrient gaps. Comparisons to dairy and other plant-based milks are included to help readers make an informed choice.

Key Points

  • Heart Health: Daily consumption of oat milk can lower LDL cholesterol due to its beta-glucan fiber content.

  • Fortification is Key: Commercial oat milk is often fortified with vital nutrients like calcium and vitamin D, crucial for bone health, especially for those avoiding dairy.

  • Be Mindful of Sugar: Many commercial oat milks, particularly flavored versions, contain high levels of added sugars that can impact weight and blood sugar levels.

  • Lower in Protein: Oat milk is significantly lower in protein than cow's milk, so it should not be relied upon as a primary protein source.

  • May Cause Bloating: The fiber and additives in some brands can cause bloating or digestive issues, especially for those with sensitive stomachs.

  • Choose 'Certified Gluten-Free': Individuals with celiac disease must select oat milk made with certified gluten-free oats to avoid cross-contamination.

  • Environmentally Friendly: Oat milk production generally uses less water and land compared to dairy milk, making it a more sustainable choice.

The Case for Taking Oat Milk Every Day

For many, oat milk serves as an excellent daily beverage, particularly for those with dietary restrictions or ethical preferences. A primary reason for its appeal is its accessibility and versatility. Made from a simple blend of oats and water, it is naturally free of lactose, nuts, and soy, making it suitable for a wide range of individuals. Additionally, its creamy texture and mild, slightly sweet flavor make it a delicious substitute in everything from coffee to baked goods.

Beyond its functional benefits, daily intake of fortified oat milk offers several nutritional advantages. Most commercial brands are enriched with essential vitamins and minerals that can support overall health. These include:

  • Calcium and Vitamin D: These nutrients are crucial for maintaining strong and healthy bones, helping to prevent conditions like osteoporosis, especially for those not consuming dairy.
  • B Vitamins (B12 and Riboflavin): Found in many fortified varieties, these vitamins are vital for energy metabolism and promoting the health of your nervous system, skin, and hair.
  • Beta-Glucans: Oat milk contains soluble fiber in the form of beta-glucans, which are known to support heart health. This fiber can bind to cholesterol in the gut, reducing its absorption and helping to lower LDL (“bad”) cholesterol levels over time.
  • Digestive Health: The fiber content also aids in digestive regularity and supports a healthy gut microbiome by acting as a prebiotic.

Potential Downsides and Who Should Be Cautious

While beneficial for many, taking oat milk every day is not without potential drawbacks. The nutritional content and presence of additives can vary significantly between brands, making label-reading essential.

  • Blood Sugar Impact: The process of turning oats into milk breaks down the carbohydrates into simpler sugars, which can cause a more rapid blood sugar spike compared to whole oats. While often not an issue for healthy individuals, those with diabetes or insulin resistance should monitor their intake carefully and opt for unsweetened versions.
  • Digestive Issues: For some, the high fiber content or specific additives like gums and stabilizers can lead to bloating, gas, and stomach discomfort, especially with high daily consumption. People with celiac disease or avenin sensitivity must also choose certified gluten-free products to avoid adverse reactions.
  • Additives and Added Sugar: Many flavored and barista-style oat milks contain significant amounts of added sugars and oils to enhance flavor and texture. Excess added sugar intake is linked to weight gain and other health issues. Furthermore, some brands use oils high in omega-6 fatty acids, which can contribute to inflammation if not balanced with omega-3s.
  • Lower Protein Content: Compared to cow's milk and soy milk, oat milk is lower in protein. This might be a concern for those relying on it as a primary protein source, such as young children or individuals with high protein needs.

Choosing the Right Oat Milk for Your Daily Routine

Not all oat milks are created equal. To make daily consumption healthier, consider the following points when selecting a brand:

  1. Opt for Unsweetened: Always check the label and choose products with no added sugars to minimize calorie and sugar intake.
  2. Look for Fortification: Prioritize brands that are fortified with calcium, vitamin D, and B12 to ensure you're getting key nutrients, especially when replacing dairy.
  3. Check the Ingredient List: Seek out brands with minimal ingredients, avoiding those with excessive oils, gums, and other unnecessary additives.
  4. Go Certified Gluten-Free: If you have celiac disease or gluten sensitivity, it is essential to choose a product that is explicitly labeled 'Certified Gluten-Free'.

Conclusion

For most healthy adults, incorporating oat milk into a balanced diet every day is generally safe and can offer several benefits, especially for those who are lactose intolerant or follow a plant-based diet. Its fiber content, heart-healthy beta-glucans, and the added vitamins from fortification make it a nutritious choice. However, key considerations include choosing unsweetened, fortified varieties to avoid excess sugar and additives, and being mindful of the lower protein content compared to dairy. For individuals with specific health concerns like diabetes, gluten sensitivity, or digestive issues, it is prudent to monitor consumption and select products carefully. Ultimately, moderation and informed brand selection are crucial for a healthy daily routine with oat milk.
