Can consuming dairy products reduce the risk of metabolic diseases like heart disease, high blood pressure, and type 2 diabetes?
### Can Dairy Reduce the Risk of Metabolic Diseases?
A new study suggests that including dairy in your diet might help protect against certain chronic diseases like heart disease, high blood pressure, and type 2 diabetes. The study, led by the Population Health Research Institute (PHRI) in Hamilton, Canada, analyzed data from nearly 148,000 people aged 35 to 70 across 21 countries over an average of nine years.
#### Key Findings
- **Whole-Fat Dairy Benefits**: Higher intake of whole-fat dairy foods such as milk, yogurt, and cheese was associated with a lower prevalence of metabolic syndrome and a reduced risk of developing hypertension and diabetes.
- **Nutrient Density**: Dairy is nutrient-dense, offering high-quality protein and essential vitamins and minerals.
- **Lactose Intolerance**: People who are lactose intolerant can still benefit from fermented dairy products like yogurt and cheese or lactose-free milk.
#### Previous Research
- **Blood Pressure**: Dairy is known to lower blood pressure, as shown in the DASH trial and other studies.
- **Diabetes and Heart Disease**: A 2017 review and meta-analysis concluded that dairy consumption might help protect against type 2 diabetes. Another study in 2016 found that dairy fat is not associated with a higher risk of cardiovascular disease.
#### Limitations and Future Research
The study relied on self-reported data, which can be prone to errors. More research, particularly randomized controlled trials, is needed to confirm these findings and understand why dairy might offer these health benefits.
#### Practical Advice
If you have or are at risk for diabetes, high blood pressure, or heart disease, consult your healthcare provider for personalized dietary advice. While whole-fat dairy may offer benefits, it’s essential to balance it with other healthy dietary choices.
In summary, while dairy, especially whole-fat dairy, shows promise in reducing the risk of metabolic diseases, more research is needed to confirm these benefits and understand the underlying mechanisms.
