Oats

Oats close up of rolled oats

Oats are a nutrient-dense whole grain known for their versatility and health benefits.

Available in various forms such as rolled, steel-cut, and instant, oats can be used in everything from hearty breakfasts to baked goods. Their mild flavor makes them a perfect base for both sweet and savory dishes. Oats are packed with fiber, particularly ß-glucan (beta-glucan), which is reported to support overall health and help fight many diseases. Oats also offer anti-inflammatory properties, aid in digestion, and provide a steady source of energy, making them a wholesome choice for any meal.

Here’s the compelling science-backed health data that I’ve found so far. If I’ve made any mistakes please let me know.

Cancer

  • Cancer Protection [2019, Sep]
    A Review Article of: 98 peer-reviewed studies including HELGA with over 120,000 subjects.
    Mostly looking at the six-year Scandinavian HELGA cohort study, this review found that “[t]he set of data indicates a protective effect of whole grains intake, including oat products, on the overall mortality and cancer risk, however the influence of oat on the incidence of different types of cancer cannot be assessed.” To summarize they found oats helpful to various degrees for breast cancerpancreatic cancer, and esophageal cancers.

Cardiovascular (Heart) Diseases

  • Mild Metabolic Disturbances [2022, Jun]
    A Meta-Analysis of Randomized Control Trials of: almost 5,000 subjects
    This meta-analysis of randomized control trials on Oat Supplementation Interventions, or OSI, or more commonly known as eating oats. With almost 5,000 test subjects (oat eaters) between the different trials, the meta-analysis researchers’ results showed: “lowered levels of blood lipids and improvements in anthropometric parameters among participants with predominantly mild metabolic disturbances, regardless of dietary background or control.

  • Cholesterol [2011, Jun]
    A Review Article of: 72 peer-reviewed sources.
    “Studies described herein have shown that, on average, oat consumption is associated with 5% and 7% reductions in total and LDL cholesterol levels, respectively. Significant scientific agreement continues to support a relationship between oat β-glucan and blood cholesterol levels, with newer data being consistent with earlier conclusions made by the FDA and JHCI.”

Dementia

  • Dementia & Mild Cognitive Impairment [2022, Aug]
    A Prospective Cohort Study of: 280 older adults over 5 years
    This study in Malaysia found that “[…] oats were also found to be protective against dementia incidence among older adults.” “Oat also exhibits strong antioxidant activity and anti-inflammatory properties that may prevent or limit cellular oxidative dysfunctions and protect against oxidative stress-related diseases, including dementia (64). Hence, owing to the high nutritional value of this dietary pattern, this study suggests that the increase in fruit and oat consumption might possess a significant role in combating neurodegenerative disease among Malaysian older adults.”

Obesity

  • Obesity & Metabolic Syndrome [2023, Feb]
    A Review Article of: 78 peer-reviewed sources.
    “Many observational and clinical studies prove that oats have a positive effect on anthropometric measures like BMI, waist circumference, waist-to-hip ratio, lipid profile, total cholesterol, weight, appetite, and blood pressure. Many studies support the concept that oats are rich in protein, fiber, healthy fats, Fe, Zn, Mg, Mn, free phenolics, ß-glucan, ferulic acid, avenanthramides, and many more.” “Hence, several clinical studies supported oats utilization against obesity, appetite hormones, and energy regulation but still, some studies have shown no or little significance on appetite.”

Kidney Disease

  • CKD (Chronic Kidney Disease) [2016, Dec]
    A Parallel Randomized Clincal Trial of: 50 subjects with CKD.
    “Intake of oats may have a beneficial effect on serum albumin and serum potassium in patients with CKD.”
    https://pubmed.ncbi.nlm.nih.gov/28003041/
  • CKD (Chronic Kidney Disease) & Microbiome [2022, Feb]
    A Randomized Control Trial of: 59, late-stage (3-5), pre-dialisis, CKD adults.
    “The findings of the study suggest that the ß-glucan prebiotic fiber supported by simplified CKD dietary advice favorably affects the gut microbiome.”
