How to get the the object from its instance field java?

Let's say I have two classes Animal and Food:

   public class Animal {
        String animalName = "";
        Food animalFood;
        public Animal(String animalName, Food food) {
            this.animalFood = animalFood;
            this.animalName = animalName;
        }
    }

    public class Food {
        String foodType;
        String foodName;
        public Food(String foodType, String foodName) {
            this.foodName = foodName;
            this.foodType = foodType;
        }
    }

    public static void main(String[] args) {
        Food dogFood = new Food("meat", "beef");
        Animal animal = new Animal("Max", dogFood);
        //problem: get animal from dogfood
    }

Is there anyway, through Reflection or otherwise to get an instance of a class from its fields (assuming that you have access to the fields)?
