Food patterns and diet are important factors to improve the lifestyle by preventing diseases. The food industry comprises complexities, and the journey for innovation in the food industry is long, from idea generation to commercialization. It is reported that diet significantly influences the evolution of CNCD (chronic non-communicable diseases), including, cardiovascular diseases, depression, and obesity. Further, product ideas and advanced packaging demand thorough data collection, testing, and certification before approaching consumers. If this work is performed manually, it brings high possibilities of errors that ultimately lead to time and money wastage with no beneficial outcomes. Here AI in nutrition plays a significant role in offering the extraordinary potential for preventing diseases and better treatment methods.

Traditional data recording and calculation methods were tedious and not free from human errors; luckily, disruptive digital technologies stepped in to record data and calculated mission-based statistics effectively. Transformation offers a strong basis to use previous data to better the next generation. Artificial intelligence and machine learning in nutrition use raw data and extract competitive features that are advantageous for predicting better dietary plans. AI in nutrition optimizes four core operations as discussed:

  • Food Science: AI automates recipe building by performing in-depth market analysis and ensures safety measures.
  • Distribution and Supply Chain: AI in nutrition helps via predictive analytics in minimizing wastes, saving costs, visual pattern recognition, agile, and accurate forecasting.
  • Customer Experience: Artificial intelligence monitors customer traffic and engagement and learns from insights to promote self-service and sales systems.
  • Manufacturing: It involves reducing risk and predictive maintenance with IoT (internet of things) to create better-connected businesses.

1. Nutrition Industry Overview

Let's have a glance

  • According to Global Newswire, it is predicted that the human nutrition market will approach $465.4 million with a CAGR of 6.6% annually by 2025.
  • Markets and Markets predicted that personalized nutrition would grow faster through programs, testing kits, and apps at 15%.
  • Wellness Creative Co predicted that obese people have higher medical costs of about $1428 than normal healthy persons, about 40% of the US population.

2. How Nutrition AI Determines People's Health Metrics?

Randomized trials in the nutrition field are complex because this technique demands sticking to a diet for years, resulting in higher human error chances. There are several factors of dietary recommendations that influence everyone differently; hence, the ideology of a universal diet plan for everyone fails here as it is impossible biologically. Artificial intelligence allows researchers to analyze big data and better understand how diet affects human health patterns, including factors influencing their nutritional needs.

AI Diet Planner: Use of AI to determine your diet plan
The food business use AI in a variety of ways, such as anticipating the influence of a taste or utilizing robots in manufacturing. A diet plan driven by AI is rapidly gaining traction, with the ability to create tailored diet programs based on our physical characteristics and exact objectives.

3. Personalized Nutritional Guide by Artificial Intelligence

Nutrigenomics strives to integrate genomic science with nutrition to improve nutritional-based artificial intelligence. DNA tests recommend a personalized diet plan focusing on specific aspects of a person's microbiome, including lifestyle, genetics, and surroundings. These suggestions are based on data extracted from billions of human dietary patterns. Such nutritional guides based on the nutrigenomic approach help scientists leverage AI for personalized recommendations and interventions.

Artificial intelligence made it possible to analyze personal health metrics and give birth to many ongoing projects in the same field. For instance, smartphone nutritional applications are developed that use deep learning to analyze photos of plates for streamlining food logging processing without human-based errors. However, a complete dataset must comprise major factors like sleep patterns, activity levels, microbiome functioning, and medication consumption. Advanced algorithms help achieve this goal by tracking important health metrics for personalized AI diet chart plan development. In the coming five to ten years, it is expected that AI and ML techniques will grow further in the nutrition and fitness department.
