If you're looking to build muscle, boost your performance, and make the most out of all your hard work in the gym, whey protein is the way to go. Research suggests that using whey protein powder along with resistance training can help maintain lean body mass and increase upper and lower-body strength. But walk through the aisles of any supplement store, and you'll see a wide variety of different protein types. So why whey? One of the major benefits of using whey protein is that it contains a wide range amino acids not seen in plant-based protein products, like pea or hemp proteins, says Marie Spano, M.S., sports nutritionist for the Atlanta Hawks, Braves, and Falcons. There is also an abundance of essential amino acids in whey protein, one of which is leucine. Leucine is needed to 'turn on' muscle building at a cellular level, according to Mike Roussell, Ph.D., author of The Meta Shred Diet. But keep in mind — you need to put in the work in the gym for your w...

As the AI wearable market matures, a new subset of devices is emerging that goes beyond simple step counting and sleep tracking: wearables that inform you how your diet affects your physiology and forecast metabolic outcomes . These devices and platforms combine continuous glucose monitoring (CGM), biometric sensing, and AI analytics to provide users with predictive insights about how food, activity, and lifestyle choices impact health. Below are the top predictive nutrition wearables and integrated systems in 2026 — ranked by insight depth, predictive capability, clinical relevance, and ecosystem support. 1. Dexcom Continuous Glucose Monitors (CGMs) Best for: Real-time glucose tracking + predictive trend watch Dexcom’s CGM systems — including the Dexcom G7 and the newer Stelo by Dexcom — remain foundational for predictive nutrition intelligence. These wearables continuously measure glucose levels every few minutes and deliver real-time data for diet response modeling. ( Wikipedia ...

Nutrigenomics (also known as nutritional genomics) is broadly defined as the relationship between nutrients, diet, and gene expression [1]. In simple terms, nutrigenomics is the study of how genes and nutrients interact. Although it is an emerging science requiring more investigation and information, existing studies show that some people are more at risk than others for nutritional deficiencies because of their genetic makeup. The launch of the Human Genome Project in the 1990s and the subsequent mapping of human DNA sequencing ushered in the ‘era of big science’, jump-starting the field of nutrigenomics that we know today [2]. Although much of the early ‘hype’ around nutrigenomics has not yet come to fruition, the field remains nascent and fast-moving, with the potential to lay the foundations of truly ‘personalised nutrition’ approaches tailored to individuals [3]. It also poses both ethical and regulatory challenges. There is potential for personal data to be misused, in a...

Introduction: The End of Guesswork Nutrition For decades, nutrition advice has been built on averages—calorie counts, food pyramids, and generalized dietary rules. Yet anyone who has tried the same diet as a friend knows the truth: the same meal can produce radically different biological effects in different people . AI-powered predictive nutrition wearables are changing this paradigm. By combining real-time physiological data with machine learning models, these devices are transforming food from a lifestyle choice into a measurable clinical input —one that can predict metabolic stress, glucose spikes, inflammation, and long-term disease risk before symptoms appear. This is not another wellness trend. It is the early foundation of diet-driven precision medicine. Why Traditional Nutrition Tracking Failed Calorie tracking, macro counting, and food diaries failed for three core reasons: They ignore individual biology Two people eating identical meals may experience opposite metabolic out...

Good nutritional care improves outcomes and is critical for your quality of life. The Pancreatic Cancer Action Network strongly recommends that patients have access to pancreatic enzymes and see a registered dietitian. What are pancreatic enzymes? Pancreatic enzymes help break down fats, proteins and carbohydrates. A normally functioning pancreas secretes about 8 cups of pancreatic juice into the duodenum, daily. This fluid contains pancreatic enzymes to help with digestion and bicarbonate to neutralize stomach acid as it enters the small intestine. Types of Pancreatic Enzymes and Their Effects 1. Lipase Effects: Lipase works with bile from the liver to break down fat molecules so they can be absorbed and used by the body. Shortage may cause: Lack of needed fats and fat-soluble vitamins; Diarrhea and/or fatty stools. Protease Effects: Proteases break down proteins. They help keep the intestine free of parasites such as bacteria, yeast and protozoa. Shortage may cau...

Dietary protein is essential for building and repairing tissues, including muscles and organs. It’s also required for the proper functioning of enzymes, hormones, and your immune system. Credit: DALL.E Essential, Nonessential and Conditionally Essential Amino Acids Made up of amino acids, proteins serve as the building blocks of your body. While there are hundreds of amino acids in nature, humans only use about 20 of them to make the proteins our bodies need. Those 20 proteins include: Alanine Arginine Asparagine Aspartic acid Cysteine Glutamic acid Glutamine Glycine Histidine Isoleucine Leucine Lysine Methionine Phenylalanine Proline Serine Threonine Tryptophan Tyrosine Valine Five of these — alanine, asparagine, aspartic acid, glutamic acid, and serine — are considered nonessential amino acids because your body can make them, although you can also get them from foods. Another six — arginine, cysteine, glutamine, glycine, p...
