Are seed oils the dietary villain social media makes them out to be, or is this just another food fear fad? Join me, Dr. Bobby Dubois, as I unravel the truths and myths surrounding seed oils like canola and safflower. 

There are NO randomized clinical trials comparing people who eat a diet with seed oils vs a diet consisting of non-seed oils like avocado, coconut, or olive.  Since we lack the key studies that we desire, I explore the topic based upon the following questions:

1. Are corn, peanuts, and the vegetables that produce these seed oils bad for you? (no evidence to support this concern)
2. Is the problem getting the oils out of these good vegetables (the extraction and denaturing process)?  Likely not.
3. Is it the contents of the seed oils themselves harmful (e.g., the omega 6 polyunsaturated fats)?  Our bodies need omega 6s and the studies that switch folks from saturated fats to seed oils show no risk of heart disease (and maybe the opposite). No evidence they they raise markers of body inflammation, and don't increase the risk of diabetes.
4. Is the harm related to the heating of the seed oils? Heating seed oils can produce potentially harmful compounds, but so does grilling a steak or salmon.
5. How much seed oil do we consume as we cook food?  Not a lot. 70% of the fat we eat comes from meat (fish, beef, chicken) and not added oils.
6. Are we blaming the wrong food?  Likely this is the key issue as cheap seed oils led to the production of yummy, highly processed, calorie dense foods.  And the problem lies there....
7. Avocado or olive oil costs 5 times what canola/corn oil costs.  Is it worth the cost to switch from seed oils to these non-seed oils? A

Take-home messages:

• i don't fear seed oils
• where they can be a concern is reusing oils over and over in a deep fat fryer where potentially worrisome compounds can accumulate
• If you have symptoms that bother you, perhaps do an N-of-1 trial of removing them from your diet.

Heart disease is the number one cause of death in the US; we understand the risk factors for it, and there are 7 key steps you can take to reduce that risk. Here is a risk calculator that will give you your 10 year risk (and test how that might fall as key problems are addressed).
1. Treat the treatable causes like hypertension, high cholesterol, smoking, diabetes, and obesity.
2. Get exercise:  the most powerful way to reduce your cardiac risk based upon key studies. And more exercise leads to additional benefits.
3. Optimize your sleep.  Studies show benefit from getting 7-8 hours/night, and having sleep regularity (similar sleep times each night).
4. Think about your nutrition. weight control impacts risk of diabetes and risk of heart disease.  The story on type of fats is complex with no differences shown in studies of low vs. high fat diets. 
5. Add some mind-body work to your life.  Although there are no long term studies demonstrating that yoga/breath work/meditation lowers mortality, short term studies show that yoga reduces blood pressure (an important cardiac risk factor)
6. Consider taking a sauna:  studies are pretty clear that taking a sauna (perhaps 3x/week for 20' each time) is associated with lower cardiac risk of sudden death.
7. Build and maintain strong social relationships. Large differences in mortality between those with and without strong social relationships.

It used to be when you got sick, you were advised to "take it easy".  But, does the evidence support this approach?  And, it isn't just an academic question since, on average, we get 2-4 colds/year and many of us will have an episode of low back pain.  And, how about COVID?  Rest or stay active?

1. Low back pain: a key randomized clinical trial showed that prolonged bed rest did not do better than usual activities.  Now we advise patients to continue activities.

2. Moderate exercise does not lessen (or worsen) cold symptoms.  But, exercise may reduce the number of colds you get.

3. Sauna use doesn't make the cold go away faster but may reduce the number of infections that you experience.

4. COVID-it appears that exercise may reduce the likelihood of fatigue, anxiety, brain fog if you do get long COVID.

5. Multiple Sclerosis-previously it was feared that exercise might worsen the disease.  Recent guidance is to be physically active.

In this episode, we explore wearables and self-monitoring tools like step counters, sleep trackers, and continuous glucose monitors (CGMs). We'll dive into the science behind these devices and share how they can help you gain insights into your health, track progress, and personalize your wellness journey. We discuss the value of self-monitoring, backed by scientific studies, and how these tools can help motivate behavior change.

Key Topics:

1. Step counters (smart watches, FitBit)
   Studies have shown that this feedback helps increase amount walked, but only if you continue to use them.  
2. Home Blood Pressure Monitoring
   Using a home blood pressure monitor, I learned that my blood pressure is higher in the morning, helping me adjust my medication timing. A review of 52 studies found that home monitoring improves blood pressure management. However, it may only be effective if used consistently.
3. Sleep Trackers and Better Sleep
   Sleep trackers like the Oura Ring can help you monitor and improve sleep habits. Studies have shown that using devices like Fitbits, paired with sleep education, can improve sleep quality. Personally, I’ve found that tracking sleep has revealed important insights into how alcohol and consistent sleep schedules affect my sleep length/quality.
4. Continuous Glucose Monitors (CGMs)
   CGMs are not just for diabetics—many people use them to personalize diet and exercise. Studies show that CGMs improve glucose control when meal plans are personalized based on individual glucose responses. For example, I learned that pizza doesn’t spike my blood sugar much, but popcorn does.

N-of-1 Trials and Personalized Health
Wearables enable N-of-1 trials—personal experiments to find what works best for you. Whether it's testing the effects of sleep habits, exercise, or dietary changes, self-monitoring helps tailor interventions to your body’s needs, offering a personalized approach to health.

Have you ever wondered why weight loss seems so elusive despite following strict diets and exercise routines? Obesity rates have skyrocketed, and we are eating more, likely due to 3 key factors:

• portion sizes are larger than ever before, often doubling what we ate 30 years ago
• the foods on our plate are more calorie dense than ever
• Foods we buy often have the perfect combination so that we crave them:  fats, carbohydrates/sugar, and salt (chips, pizza, ice cream)

My key thoughts on losing weight include:

• All diets can work, and ultimately no approach wins out over all of the others (e.g., keto, intermittent fasting, vegan, Mediterranean).  Ultimately, weight loss is about the number of calories consumed vs. burned.
• The new GLP-1 obesity drugs have taught us that eating too much is not just about will power--folks who struggled all their lives to lose weight, instantly feel more full and less hungry once starting them.  These drugs also help folks lose about 15% of their body weight

Evidence based strategies that might help you to lose weight

1. Be more aware of portion size and how many calorie dense and "craving" foods you eat (fat/carbs/salt).  For me, portion size has been the key.
2. Choose a diet that works for you.  And switch them up.
3. Give your brain time to adjust (20-30') before eating more.  That satiety lag is real and if you start with small portions and wait, you may feel full and satisfied.
4. Protein (and fat to a lesser extent) helps reduce our hunger.

Perhaps try an N of 1 study on yourself with some of the strategies above.

Our bodies are 60% water and water  is really important.  But, It is not clear the origin of drinking  8 glasses of water per day. There were no studies that scientifically show that this number is the correct amount.  I vote that it is an "urban myth."  Good report summarizes important information about how our body uses water

But, water is crucial for us, just not that mythical amount.  Our body uses water in the following ways:

• urine to excrete byproducts of what we eat (perhaps 2-3 glasses of water per day needed)
• respiratory loss (perhaps 1 cup/day)
• "insensible loss"-sweating to maintain body temperature (wide range depending upon temperature--2 glasses of water/day up to 1 gallon or more)
• stool perhaps 1/2 cup of water per day

My take on the scientific evidence:

1.        The body is amazing at controlling our water balance.  Trust it!  There is no evidence based reason to focus on getting 8 glasses of water each day.  And, we get substantial fluids from our food/morning coffee/milk or sodas at meals...

2.        If you are thirsty, drink.  If your urine has gotten much darker, then perhaps drink.  Otherwise trust your body
3. these observations don't apply if you have kidney disease or are elderly.  Ask your doctor.

Tasty water "tidbits":  drinking extra water each day...

•  does not seem to make our skin look young and full (might hydrate it a little but not clear if it looks better)
• does not seem to affect our joints/cartilage (no evidence found here...)
• does not reduce dry eyes
• probably doesn't help us eat less 
• DOES reduce the risk of recurrent urinary tract infections

• Approximately 40% of the risk for cognitive decline is preventable through lifestyle changes and proactive measures. 
• Nearly 7 million Americans are affected by Alzheimer's, with numbers expected to double in the coming decades. It's the sixth leading cause of death, costing the US around $800 billion annually.
• Not Inevitable: Cognitive decline is not an inevitable part of aging, as demonstrated by figures like Barbara Walters and Henry Kissinger, who remained mentally sharp well into their later years.

Part 2: Strategies That Work

1. Exercise: Regular physical activity is associated with a 28% reduction in the likelihood of Alzheimer's. Dancing, in particular, has shown benefits due to its combination of physical and mental engagement.
2. Sleep: Adequate sleep (around seven hours per night) is crucial, with poor sleep increasing the risk of Alzheimer's by 68%.
3. Smoking: Smoking cessation is critical, as smoking is linked to 5% of dementia cases.
4. Blood Pressure Control: Managing hypertension can greatly reduce the risk of cognitive decline
5. Obesity and Diabetes: Both conditions are associated with an increased risk of dementia.
6. Sauna Use: Regular sauna use correlates with a reduced risk of dementia, with benefits increasing with frequency of use and time/session.
7. Hearing Loss: Treating hearing loss may lower the risk of cognitive decline by maintaining cognitive stimulation.
8. Alcohol Consumption: Reducing alcohol intake can decrease the risk of cognitive impairment.
9. Social Engagement: Maintaining strong social connections is associated with a reduced risk of dementia.

Part 3: Strategies That Don't Work

• Omega-3 Supplements: No substantial evidence supports their role in preventing cognitive decline.
• Brain-Focused Diets: Diets like the MIND diet have not shown significant benefits in reducing cognitive decline in clinical trials.

Part 4: Unclear or Emerging Strategies

• Probiotics, Viagra, and Multivitamins may have benefits.
• Brain Training Games: While they may improve specific skills, there is limited evidence that they prevent general cognitive decline. Newer approaches have some promising results
