Scientists have discovered that the MRAP2 protein enhances the signal from the MC4R hunger receptor, opening a new avenue for combating obesity and protecting the brain. A key finding in appetite control Appetite is one of the most complex biological processes in the human body. It depends not only on willpower, but also on…
Alzheimer’s is a complex neurodegenerative disease, and although many cases are not due to a single genetic cause, evidence suggests that genes play a significant role in its risk and development. Below, I review the main genetic pathways involved, recent evidence, and current challenges. Inheritance and genetic risk estimates Twin and family studies have…
In our nutrition practice, we believe that each person is unique. Therefore, our approach is not just to offer you a standard diet, but rather a 100% personalized nutritional plan tailored to your needs and how your body truly functions. This is where nutrigenomics and genetic testing come into play . What is nutrigenomics and why is it important to…
1) Ensure complete protein: tyrosine + phenylalanine from the diet Tyrosine is obtained directly from protein foods and also by conversion from phenylalanine . Prioritize at each meal: legumes (lentils, chickpeas, beans, soy/tempeh/tofu), eggs and dairy products , fish and lean meats , nuts and seeds (almonds, peanuts, pumpkin, sesame). Recent review: Nutrition (macros and micronutrients) modulates the diet-microbiota-thyroid axis and, therefore, thyroid function. ( MDPI )…
Type 2 diabetes is one of the most prevalent chronic diseases in the world. As cases increase, so do studies on how to effectively prevent and manage it. Traditionally, treatment has focused on lifestyle changes, such as diet and exercise, along with medications. However, nutrigenomics, the science of studying the interaction between genes and…
Two new meta-analyses published in July and August 2025 offer a more nuanced view of the role of selenium in human health, particularly in relation to mortality, oxidative stress, and cancer. Clear benefits on general and cardiovascular health A meta-analysis published in Frontiers in Nutrition (July 2025) confirms that adequate blood selenium levels are inversely…
Spanish researchers from the Center for Genomic Regulation have participated in the creation of the most comprehensive catalog of genetic variations to date, deciphering some of the most difficult-to-identify and overlooked regions of the human genome . This breakthrough, published this Wednesday in two articles in the journal Nature, will accelerate the diagnosis of rare diseases and cancer . “Each human genome has around…
At the Nutrigenomics Institute, we firmly believe in approaching health holistically: body, mind, and environment. The gut-brain axis , widely documented by the scientific community, reveals a two-way communication where the gut microbiota plays a central role. Scientific evidence A comprehensive review recently published in Cureus explores how microbiota influences mood disorders. The study highlights that certain gut bacteria—such…
A team of researchers from Spain, Boston (USA), and Bubendorf (Switzerland) has delved into how adipocytes (fat cells) process vitamin D. The recently published findings reveal a key fact: vitamin D3 tends to remain trapped in fatty tissue. Vitamin D, which we obtain through sun exposure or supplements, does not circulate freely throughout the…
Can vitamin D help slow biological aging? A new study suggests it can. According to research published in The American Journal of Clinical Nutrition (May 2025), taking 2,000 international units (IU) of vitamin D3 daily may help slow the shortening of telomeres , DNA structures that are closely linked to aging and chronic diseases. And why is…
Stroke, dementia and depression are more common in people with short telomeres. Leading a healthy lifestyle reduces this risk. Telomeres, the gene-protecting structures located at the ends of chromosomes considered a biological marker of aging, could determine our risk of stroke, dementia, and depression in old age. A study published in the scientific…
Bariatric surgery shows better results than GLP-1 in a real-life study: the scalpel achieves five times more weight loss than drug treatment after two years. After two years, bariatric surgery achieves five times greater weight loss than GLP-1 receptor agonists. This is the main conclusion of a real-life study just presented at the American…
