Eating less red meat is an undeniable trend of 2019. Reasons vary from cutting out inflammatory toxins in your diet, to wanting to lower your carbon dioxide footprint, to deciding against unethical farming practices.
However, cutting out red meat from your diet also means you are likely eliminating your main dietary source of iron.
Having sufficient iron in your system is critical to hair, bone and nail health (to name a few things). When your body lacks iron, it cannot make hemoglobin (the protein in your red blood cells), and cannot transport oxygen around the body for growth and repair.
So if you switch to a vegan or vegetarian diet, you may experience thinning hair as a result.
Luckily, there are many iron-rich plant-based solutions! Incorporate more beans (like lentils, soybeans, kidney beans) and leafy greens (such as spinach, swiss chard, kale) in your diet to increase your iron intake from non-meat and non-dairy sources.
