A new study conducted by UK Biobank challenges the common belief that plant-based milk alternatives are always healthier, particularly in terms of mental health. Published in Frontiers in Nutrition, the research tracked over 350,000 people and explored the link between milk consumption and mental health, specifically anxiety and depression.
Key Findings of the Study
- Mental Health Risks with Plant-Based Milk:
- The study found that individuals who consumed plant-based milk alternatives like soy, oat, or almond milk were more likely to suffer from depression than those who drank cow’s milk.
- Specifically, those who drank semi-skimmed cow’s milk had a 12% lower risk of depression and a 10% lower likelihood of experiencing anxiety when factors such as age, physical health, and income were taken into account.
2. Dairy Milk vs. Plant-Based Milk:
- Skimmed milk was found to have no significant impact on mental health, while consuming milk with no dairy was linked to a 14% increased risk of developing depression.
- This suggests that dairy-based milk, rich in nutrients like calcium, could play a role in boosting serotonin production, which is associated with mood regulation.
3. Protective Effect of Semi-Skimmed Milk:
- The study indicated that semi-skimmed milk, in particular, may have protective effects for brain health. The fatty acid profile of semi-skimmed milk might offer more protection against mental health issues compared to full cream or skimmed milk.
Potential Mechanisms Behind the Findings
- Calcium and Nutrients: Dairy milk is a rich source of calcium, lactose, lipids, protein, and other essential minerals, all of which contribute to human health. Calcium, in particular, plays a role in activating pathways that may help increase serotonin levels, a neurotransmitter linked to mood regulation.
- Brain Protection: The fatty acids in semi-skimmed milk could provide greater cerebral protection, potentially reducing the risk of both depression and anxiety.
While plant-based milk alternatives are often viewed as healthier, especially by those following vegan diets, this study suggests that semi-skimmed cow’s milk may offer benefits for mental health, potentially lowering the risks of anxiety and depression. The research points to the complex nutritional factors at play, emphasizing the role of milk’s nutrient profile in supporting brain health.
