In this episode, we speak with Mariana Arostegui, an integrative nutritionist specializing in digestive health, known for her holistic approach that integrates science, clinical experience, and common sense. For years, Mariana has worked to help people reconnect with their bodies and understand that health depends not only on what we eat, but also on how we live, feel, and relate to others.During our conversation, we debunk many common myths related to omeprazole, red light, gluten, sun exposure, allergies, and more. Mariana shares her vision of how the body is capable of self-regulation when we treat it with respect, and she critiques the over-information that generates confusion and misdiagnoses. We also address topics such as the immune system, antibiotic resistance, excessive sanitization in childhood, and the influence of emotions on our physical health. Topics we explore 00:00 Intro 05:09 How to expose ourselves to the sun correctly? 06:24 Is the famous red light useful for anything? 11:28 Over-information in the world of health 18:35 What does omeprazole actually do in your body? 26:56 The body is perfect 34:34 Is it possible to live without omeprazole? 39:00 Allergies and the immune system 45:36 Is gluten an enemy or does it depend on the context? 51:18 Are we over-sanitizing children? 53:41 Why is there increasing resistance to antibiotics? 59:35 What does your immune system have to do with your emotions? The most important moments Digestive biohacking and common sense Emotional priority [00:00]: Mariana emphasizes that emotional health (inner peace, spirituality, stress and conflict management, love) is the most important lever for health, even above supplementation and extreme diets. Information overload [12:04]: She warns about the stress and anxiety generated by information overload on social media and podcasts. She recommends limiting exposure and focusing on the "basics" before seeking complex solutions. The most important things are free [11:32]: Much of what we can do for our health is free, such as exposing ourselves to the sun, spending time in nature, laughing, and connecting with others. The importance of sunlight and circadian rhythms The sun as a driver of life [04:13]: The sun is fundamental for the functioning of our internal ecosystem, including the gut microbiota and circadian rhythms. Ultraviolet light and biodiversity [05:01]: Exposure to ultraviolet light (especially between 11 a.m. and 5 p.m. in Madrid, with peaks at 2-3 p.m.) increases microbial biodiversity, even with the same diet. Hormones and immune system [05:55]: The sun is crucial for hormone production (like vitamin D), improves mood, and boosts the immune system by producing antimicrobial substances. Red light as support [07:00]: Red light can help artificially extend the day without altering sleep preparation, especially useful in modern environments. However, it does not replace direct sun exposure. A red light bulb without "flicker" is better than nothing [08:29]. Infrared lamps are an extra, but sunrise and sunset offer this light for free [09:41]. Day and sleep [15:36]: The intensity of sunlight during the day improves sleep quality, where the body detoxifies, reduces inflammation, and regenerates. Healthy aging depends on good sleep. Outdoor exposure [16:31]: It is essential to spend time outdoors, even on cloudy or rainy days, since sunlight is still present and provides crucial information to our cells and microbiota. Omeprazole and its impact on digestive health Proton Pump Inhibitor (PPI) [19:02]: Omeprazole inhibits the production of hydrochloric acid in the stomach, which can be useful in cases of ulcers or severe irritation of the mucosa. However, its chronic use without necessity is harmful. Consequences of prolonged use [24:02]: Malnutrition: The lack of stomach acidity prevents the correct activation of digestive enzymes and the absorption of proteins, which can lead to hair loss, muscle weakness, bone mass loss, and in extreme cases, neurological problems. Micronutrient deficiencies: It hinders the absorption of vitamin B12, iron, and calcium, which can cause anemia, bone loss, and osteoporosis. Dysbiosis: It alters the balance of the microbiota, increasing predisposition to infections (Clostridium, Salmonella) and chronic digestive problems. Hypochlorhydria vs. Hyperchlorhydria [28:43]: In 99% of cases, heartburn and reflux are caused by hypochlorhydria (acid deficit), not by excess. The "stressed" or "blocked" stomach does not function well, and mucosal irritation (due to poor diet, stress, or lack of sleep) is what causes the pain. Strategies for weaning off omeprazole [34:57]: Regeneration: Use natural regenerators (zinc carnosine, aloe vera, sea buckthorn, lion's mane) for at least two months while still taking omeprazole. Decoctions: Flaxseed or kuzu broths to create a protective layer on the mucosa. Digestive enzymes: Supplement with protease enzymes to help digest proteins if the stomach does not produce enough acid. Staggering: Gradually reduce the omeprazole dose (e.g., every other day) once the mucosa has regenerated and symptoms improve. Root cause [27:53]: It is essential to address the underlying cause of digestive problems, such as stress, poor diet, lack of sleep, or the use of anti-inflammatories. Allergies and gut microbiota It is not normal to have allergies [39:52]: Mariana states that allergies indicate a lack of adaptation to the ecosystem. The immune system "makes a mistake" by attacking something it shouldn't. Allergy factors [40:51]: Drop in microbiota biodiversity: Modern lifestyle, birth method (cesarean sections), diet (formula instead of breastfeeding), and excess hygiene reduce bacterial diversity, which is key to modulating the immune system. Stress: Immune systems on high alert (due to stress in children or adults) are more prone to allergic reactions. Excess intestinal permeability ("leaky gut") [42:20]: Damage to the intestinal mucosa that allows toxic substances, metals, and unwanted microbes to enter the bloodstream, triggering exaggerated immune responses. Gluten, medications, parasites, and stress are factors that increase permeability. Evidence from ancestors [48:32]: Communities that live similarly to our ancestors (such as the Hadza in Africa) show much greater microbial biodiversity, with fewer metabolic and inflammatory pathologies, despite their varied diets. Microbiota and environment [50:54]: Our environment (plants, soil, contact with nature) interacts with our microbiota, communicating to our immune system that "we are at home" and that there is no need to attack elements like pollen. Generational loss [52:46]: It is estimated that each generation loses 10% of microbial biodiversity, leading to an increase in autoimmune and allergic diseases. Candida and its resistance Intelligent fungi [55:28]: Fungi are intelligent beings that become pathogenic when the ecosystem becomes aggressive toward them. Causes of chronicity [56:19]: Two key factors in the pathogenicity of Candida are electromagnetic waves and toxicity/heavy metals in the body. An exhausted or malnourished immune system, a diet rich in carbohydrates, processed foods, and alcohol, and the use of antibiotics (which kill bacteria but not fungi) create an environment conducive to their growth. Holistic approach [58:49]: To treat Candida, it is essential to address the emotional context, stress, diet, heavy metals, and protein digestion. There is no single protocol; treatment is adapted to each person's "blind spots." The paradox of change [01:01:32]: Many people want to improve their digestive health but are unwilling to make the necessary lifestyle changes, which perpetuates the problem. Final reflections Health is simplicity [01:02:50]: Health is found in humility, presence, spirituality, contact with nature, and conscious consumption. Prioritize the basics [01:15:50]: Mariana always begins her consultations by addressing stress, sun exposure, nature, and love before resorting to dysbiosis tests or supplements. Dysbiosis test [01:13:31]: These are a useful tool to identify pathogens or markers of infection, but they do not reflect the complete microbiota. They must be interpreted by qualified professionals. This episode is an invitation to return to the basics, listen to our body, and understand that health is a complex ecosystem where emotions, the environment, and diet are intrinsically connected.
