Plant-based and vegetarian diets are best for blood and liver health

The study conducted in Greece sheds light on the potential benefits of adopting a plant-based or vegetarian diet and how it can positively influence various aspects of blood health and liver function. Let’s delve into this in more detail and emphasize the significance of a plant-based diet, especially in the context of liver health.

Impact of Protein Sources on Blood Health: The study categorized protein sources into three groups: “haem” animal-based (e.g., red meat), non-“haem” animal-based (e.g., chicken), and plant-based protein. Here are the key findings related to blood health:

1. “Haem” Animal-Based Proteins: Individuals who primarily consumed protein from “haem” animal sources showed elevated levels of hemoglobin and hematocrit in their blood. These markers are associated with an increased risk of certain health issues.
2. Non-“Haem” Animal-Based Proteins and Plant-Based Proteins: Surprisingly, individuals who derived their protein from non-“haem” animal sources (like chicken) and plant-based sources did not exhibit significant effects on these blood markers. This suggests that opting for non-“haem” animal sources or plant-based protein may have a more neutral or favorable impact on these blood markers, even after considering other lifestyle and dietary factors.

Promoting Liver Health with a Plant-Based Diet: In simpler terms, the findings from this study highlight the potential benefits of a plant-based or vegetarian diet, particularly rich in soy as a meat and fish substitute, and focused on whole grains. Here’s how this can promote liver health:

1. Reduced Risk of Fatty Liver Issues: Adopting a vegetarian diet and replacing sugary and processed foods with whole grains may be associated with a reduced risk of developing fatty liver issues, especially among individuals with a high body mass index (BMI).
2. Benefits for Those Who Are Overweight: Such dietary choices appear to be particularly beneficial for individuals who are overweight, as they can contribute to improved liver health. A vegetarian diet can help in maintaining a healthy weight and reducing the risk of fatty liver disease.

The Impact of Animal Proteins on Liver Health: In addition to the Greek study, other research has shown that animal proteins, particularly those from “haem” sources, can contribute to the progression of liver issues. For individuals with liver problems, especially cirrhotic livers, animal proteins have been linked to an increase in fibrosis, which is the scarring of liver tissue. To prevent the exacerbation of liver problems, individuals with liver issues should consider reducing or eliminating animal protein from their diets and focus on plant-based alternatives.

In conclusion, these findings collectively emphasize the potential benefits of adopting a plant-based or vegetarian diet for both blood health and liver health. Such dietary choices can contribute to better overall well-being and are especially important for individuals with high BMI or liver problems. It’s important to consult with a healthcare professional or nutritionist for personalized dietary recommendations, especially if you have specific health concerns.
