  In healthcare, artificial intelligence (AI) has been changing the way doctors
and health experts take care of people. This paper will cover how AI is making
major changes in the health care system, especially with nutrition. Various
machine learning and deep learning algorithms have been developed to extract
valuable information from healthcare data which help doctors, nutritionists,
and health experts to make better decisions and make our lifestyle healthy.
This paper provides an overview of the current state of AI applications in
healthcare with a focus on the utilization of AI-driven recommender systems in
nutrition. It will discuss the positive outcomes and challenges that arise when
AI is used in this field. This paper addresses the challenges to develop AI
recommender systems in healthcare, providing a well-rounded perspective on the
complexities. Real-world examples and research findings are presented to
underscore the tangible and significant impact AI recommender systems have in
the field of healthcare, particularly in nutrition. The ongoing efforts of
applying AI in nutrition lay the groundwork for a future where personalized
recommendations play a pivotal role in guiding individuals toward healthier
lifestyles.
