Perhaps you could start by helping your mother understand which ingredients she is using that may not be vegan. It's my experience that some foods, especially processed foods, that you would intuit to be vegan, are in fact not. Additionally, there are some foods, such as honey, that you may consider vegan and your mom may not. "Vegan" may be a brand new term to mom, or it may mean "vegetarian" to her. In either instance, clarification around exactly what vegan means may be clear the challenge.

Secondly, perhaps you could have a sincere conversation with your mother about the reasons you've chosen to enjoy a plant-based diet. Understanding your reasons may help your mom be more mindful about the ingredients she uses when cooking for you. Changing habits can be challenging and adapting to the demands of someone else's choices can be harder yet. If mom is made aware of the sincerity of your desire to be more mindful of the world in which you live, and/or the strength of your commitment to take the best possible care of your self she will find it easier to modify what may be years of cooking behavior.

Lastly, if it's possible for you to do so, take the opportunity to prepare some of your own foods. if it is not feasible in your household for you to do your own cooking perhaps offer to help your mom with some of the meal preparation for the family. That would provide you the opportunity to assure that the correct ingredients are being used for the food that you eat and maybe help your mom realize that you can create tasty nutritional plant-based meals.

Though your circumstance appears to be challenging, it does offer the opportunity for some sincere conversations about the benefits of a plant-based diet. Who knows? After some conversation maybe other members of your family will decide they'd like to join you in enjoying the healthier more joyful plant-based way of eating!

Here are some books that may make great gifts to your mom:
