Soy Connection

Omega-6 fatty acids, especially those found in seed oils, are often caught in the middle of nutrition debates. But new research is helping shift the conversation toward a more evidence-based understanding of how these fats function in the body. A large study recently published in the British Journal of Nutrition offers a clearer picture, showing that linoleic acid, the most common omega-6 fatty acid, may be associated with more favorable body composition.

If you’re a dietitian or nutritionist, you’re already familiar with the importance of protein. "Protein" comes from the Greek word “proteios,” which means of the first rank or position, and primary importance. The word was originally coined in 1838 and was chosen to represent the fundamental nature of protein’s role in human nutrition. However, the nutritional importance of protein is also due to its constituent amino acids—the fundamental molecule that serves as the building block for protein.

Seed oils have become one of the most debated topics in nutrition, despite decades of evidence supporting their role in cardiovascular health. Not to mention that most seed oils are high in linoleic acid, one of two essential fatty acids humans need because the body cannot produce it on its own, but it is required for our bodies to function. Chances are, your patients have seen claims linking seed oils to inflammation, weight gain, oxidative stress, and chronic disease.

Key Takeaways: Review the latest evidence on soy and menopause, including research showing that soy isoflavones do not affect key markers associated with estrogen-related cancers in postmenopausal women. Explore how soy may support women during the menopausal transition by helping reduce hot flashes for some individuals while also promoting heart health as estrogen levels decline.

Gut health plays a central role in human health and wellness. For children in particular, it supports several key developmental factors like growth, immunity, and long-term well-being – and parents and caregivers are increasingly recognizing the connection between gut health and overall child development. One promising dietary strategy to support gut health is the inclusion of fermented soy foods, which provide beneficial bacteria, enhanced digestibility, and vital nutrients for growth.

Happy Soy Foods Month! Soy foods have been enjoyed around the world for generations, and research continues to show they can be a healthy addition to everyday meals. Foods made from soybeans – a type of legume – include options like tofu, edamame, tempeh, soy milk, miso, soy yogurt and soybean oil, as well as ingredients used in many plant-based foods like soy-based meat alternatives.

The 2025–2030 Dietary Guidelines for Americans (DGA) mark a continued emphasis on whole, nutrient‑dense foods for health and well-being. Below, read more about how high‑quality, affordable plant‑based proteins like tofu or tempeh can provide value in balanced eating patterns that align with the latest guidance.

Meta-analyses of the clinical data consistently show that soy protein lowers circulating LDL-cholesterol (LDL-C) levels. The most recent meta-analysis demonstrating this was published in 2015, while the first appeared in 1995. Four years later, after conducting its own analysis of the literature, the U.S. Food and Drug Administration (FDA) authorized a health claim for soy protein and reduced risk of coronary heart disease.

Heart disease continues to be the leading cause of death in the United States, resulting in more than 655,000 deaths in 2018.1 Data from observational and clinical trials have led to the identification of dietary approaches that reduce the risk of heart disease, like adding soybean oil to your diet. But is soybean oil good for you?

Conversations about ultra-processed foods (UPFs) are everywhere—on social media, in the news, and in your patients’ questions. The lack of a universal definition for UPFs only adds to the confusion, particularly when it comes to foods like soy-based meat alternatives. While these products are labeled as ultra-processed, they may offer important health benefits.
