Explore how AI in nutrition can be used to track food intake, suggest recipes, offer personalized dietitian services, and its impact on the medical industry.
Eating healthy and staying fit is a goal many of us strive to achieve. According to a survey, 70% of people want to be healthier, and for 50% of them, eating healthier is a top priority. Occasionally, we might rely on advice from doctors and dietitians. However, this can be time-consuming and involve appointments and meal tracking. Meal tracking, in particular, can be tedious and prone to mistakes.
AI and computer vision can make eating healthy simpler and more accessible. They can help analyze what you eat, track your nutrition, and even suggest recipes based on your health goals. These technologies can also help identify allergens to make meal planning easier and safer for people with dietary restrictions. In this article, we’ll take a closer look at how these technologies can be used for tasks like nutrition tracking and suggesting recipes. We’ll also see how AI in nutrition is affecting the healthcare industry. Let's get started!
Various health complications can arise from improper nutritional intake. Researchers have found that consuming too much or too little of certain foods and nutrients can increase the risk of heart disease and stroke. That’s why it’s very important to track your nutritional intake. Traditionally, tracking nutritional intake involves manually recording the foods you eat, estimating portion sizes, and looking up nutritional information, which can be time-consuming and involve a margin of error. With AI and computer vision technologies, tracking nutrition is easier now than ever before.
When you sit down to eat, you can take a picture of your bowl or plate, and computer vision models can analyze the image to identify the different foods. The AI system can then estimate portion sizes and provide detailed nutritional information. For example, using object detection, computer vision systems can accurately identify food items on your plate.

These identified food items can then be matched to a large database of nutritional information. Advanced algorithms like depth estimation can help estimate portion sizes. Once the foods are identified and portion sizes estimated, the system can calculate the calories, macronutrients (like proteins, fats, and carbohydrates), and micronutrients (such as vitamins and minerals), to give you a detailed nutritional breakdown of your meal.
One of the most popular applications of computer vision in meal tracking is through mobile apps. Let’s take a quick glance at a few exciting AI meal-tracking options.
SnapCalorie is an app that uses computer vision to estimate calorie content and macronutrients from a photo. Trained on 5,000 meals, it reduces calorie estimation errors to less than 20% and outperforms most humans. The results can be logged in a food journal or exported to fitness platforms like Apple Health.
Similarly, an interesting innovation driving AI nutrition tracking is the LogMeal API. It uses deep learning algorithms that are trained on large datasets of food images to accurately detect and recognize foods. LogMeal’s models achieve 93% accuracy across 1,300 dishes and provide detailed nutritional analysis, ingredient detection, and portion size estimation. The LogMeal API can be easily integrated into apps to create meal-tracking solutions for restaurants, self-order kiosks, food tech startups, healthcare providers, and other consumers.

AI can suggest healthy recipes based on what you have available in your kitchen. Computer vision techniques like segmentation can identify different ingredients in an image of your fridge or pantry. Based on this, a large language model (LLM) like ChatGPT can then suggest recipes using generative AI. Since you can prompt an LLM, you can also specify dietary restrictions like vegan, gluten-free, or low-carb, and the AI system will curate recipe suggestions to meet your criteria.
"Sous Chef", a customized version of ChatGPT, is a great example of this technology. It can suggest recipes based on what you have. You can either prompt in the ingredients or upload an image of what you have in your fridge.
You might be wondering, do we really need such a system? AI recipe suggestion systems offer many benefits like reducing food waste by making good use of available ingredients and increasing meal variety with gourmet dishes. They can also help you maintain a balanced diet. For instance, personalized meal plans suggested by an AI recipe generator can help you achieve fitness goals. These systems can also make cooking a lot more fun and creative.
There’s a lot of fascinating work being done in the food and nutrition industry regarding AI. Let’s take a look at some of the startups that are integrating AI into the food we eat every day.
Journey Foods, a USA-based startup, provides ingredient intelligence to develop and launch new packaged food products. Their data science platform, JourneyAI, analyzes millions of ingredients and supply chain data to find the ideal ingredient for each product. It collects and stores vast amounts of data on chemicals and nutrients to create the best formulations of food products. The platform also enables packaged food manufacturing companies to better manage entire product life cycles through data-driven food discovery.
Another innovative startup in the nutrition industry is Viome. Viome uses artificial intelligence and mRNA sequencing technology to offer personalized nutrition and wellness recommendations. They provide at-home tests that analyze the microbiome and gene expression to give precise insights into an individual's health. These insights help identify the underlying causes of microbial imbalances and inflammation. Based on this information, Viome prescribes custom-made supplements and dietary recommendations tailored to each person's unique biochemistry. By focusing on preventing chronic diseases and addressing root health issues, Viome makes advanced health management accessible and personalized.

While AI-enhanced nutritional systems offer many benefits, we also need to understand some of their drawbacks. One major issue is data privacy and security. These systems need access to sensitive personal health and dietary information. If this data isn’t well-protected, it could be misused or stolen.
Also, there’s the concern of bias in AI algorithms. If the training data isn’t diverse enough, the recommendations might not be accurate for everyone, potentially leading to poor advice for certain groups of people. Another issue is the risk of becoming too reliant on technology. AI can provide helpful insights, but it shouldn’t replace the expertise of human nutritionists and healthcare providers.
AI-powered nutrition tracking and dietitian systems are set to reshape the medical industry, changing the roles of human dietitians and healthcare professional. They also give the public more options when it comes to getting advice about nutritional intake. Around 40% of people don’t feel they need to speak with their doctor before adding a supplement to their daily routine. AI makes it easier to get an expert opinion and can encourage the public to get more input before making changes to their nutritional intake.
It’s likely that an AI transformation can fundamentally alter how nutrition and dietary management are handled. Alexandra Kaplan, a dietitian-nutritionist at Core Nutrition based in Westchester, New York, states, "Assuming it's accurate (AI), it could be very useful because it would help me know the exact portion of what's on the plate and then what's in the food, so it could be helpful for patients to know what they're eating at that meal."
Rather than replacing human dietitians, AI can serve as a powerful tool that complements their expertise. AI can provide data-driven insights that can support clinical decision-making which helps dietitians develop more effective treatment plans. For instance, AI can identify patterns in the dietary habits of a patient contributing to chronic diseases, and allow dietitians to intervene earlier and more effectively.
Computer vision and AI can make it a lot easier to track what we eat and can even be your personal dietitian. These technologies can be used to help improve patient health by providing accurate monitoring and tailored diet plans, while also lowering healthcare costs by making most of the complicated dietitian processes more efficient. Although AI has some limitations, like accuracy issues and a lack of personal human touch, AI innovations can complement human expertise and enhance overall nutritional care. We may still be a long way off from the food replicators of Star Trek, but AI in nutrition is reshaping the future.
