🐶 Nuevo estudio sobre alergias alimentarias

Los investigadores descubrieron que la mayoría de los perros con alergias alimentarias requieren exposiciones de moderadas a grandes antes de que aparezcan los síntomas. En promedio, los brotes no se manifiestan hasta aproximadamente 4 días después de ingerir el ingrediente desencadenante.
Otro hallazgo importante fue que las reacciones alimentarias a menudo son tardías, con síntomas que aparecen varios días después de la exposición. La mayoría de los perros tampoco reaccionaron a cantidades mínimas de proteína alergénica. En cambio, la mayoría necesitó exposiciones más grandes antes de que se desarrollaran signos clínicos.

Este estudio destaca por qué la diversidad dietética es importante. Alimentar a un animal con un solo tipo de comida durante toda su vida es una recomendación que a menudo promueven las empresas de alimentos para mascotas para generar lealtad a la marca, no muchos veterinarios y investigadores enfocados en la nutrición.

Esa es una de las razones por las que recomiendo que los perros sanos consuman una variedad de proteínas y alimentos a lo largo de su vida, en lugar de la misma proteína o marca año tras año. Esto ayuda a mantener la flexibilidad dietética y puede favorecer un microbioma intestinal más diverso.

Si tu animal solo puede tolerar una proteína, vale la pena explorar por qué.

Tiny pieces of plastic. Potentially big consequences.

Independent researchers specializing in microplastics, pollution, and toxicology analyzed 30 popular🏆 dog and cat foods🐾, with the findings published in the peer-reviewed journal Environmental Toxicology and Chemistry. Microplastics were found in 76% of the products tested🔬 and 84% of the brands analyzed, including products from brands such as Royal Canin, Pedigree, Nature’s Variety, Iams, Whiskas, Harringtons, Lily’s Kitchen, and Scrumbles. Contamination was found across wet foods🥫, dry foods, value brands🏷️, mid-range brands, and premium brands, although value-priced foods had the highest levels. Some of the most contaminated foods could expose a large dog to more than 2,300 microplastic particles per day or almost a million a year! The most common plastics identified were polyester, polypropylene, polyethylene, and polyacrylamide, suggesting contamination may occur throughout the food supply chain, from ingredients and manufacturing to packaging.

Studies have linked microplastics to gut microbiome disruption, gut barrier damage, inflammation, reproductive issues, and organ dysfunction.

Emerging research suggests nutrients such as sulforaphane-rich broccoli sprouts, NAC, glutathione, milk thistle, chlorella, and glycine can help support the body’s natural antioxidant, liver, gut, and cellular defense systems that can be stressed by environmental contaminants.

This is one reason why Dr. Karen Becker included these ingredients in LIVER LIFT™, a science-driven, nature-powered formula designed to support the liver, kidneys, blood, lymphatic system, and healthy cellular function in the face of everyday environmental stressors.

A new peer-reviewed study analyzing commercial dog and cat foods found multiple mold toxins present across all diets, with higher levels in foods containing more cereal ingredients like corn🌽, wheat🌾, barley, oats, and rice🍚. Researchers detected 63 different compounds⚠️, with common toxins such as DON, zearalenone, and fumonisins often appearing together at low levels.

While all amounts were below safety limits, the study highlights uncertainty around long-term and combined exposure. Pets are exposed to multiple toxins at once, and the effects of these mixtures over time are still largely unknown. Broader research suggests some mycotoxins may act additively or synergistically, potentially amplifying their impact, and have been linked to immune and gut changes in animal models.

Contaminated corn🌽, in particular, has been associated with some of the largest pet food recalls and highest reported pet death events in modern history. Notably, the Midwestern Pet Foods SPORTMiX recall was linked to over 130 dog deaths and 220 illnesses, while a Sunshine Mills recall affected multiple brands. Corn’s susceptibility to heat, humidity, and poor storage makes it a common source of aflatoxin contamination.

In a 6-week head-to-head trial, a turmeric extract outperformed glucosamine + chondroitin. Dogs showed less pain and limping, better joint movement and weight-bearing, and improved activity and quality of life. Both helped, but turmeric consistently delivered stronger results.

This wasn’t a combo, it was a direct comparison: turmeric vs glucosamine + chondroitin.

Key insight: managing pain and protecting cartilage are not the same. Most joint supplements aim to support cartilage, not reduce pain. This study highlights the need for both approaches if you actually want to improve how dogs feel and move.
