Fructose’s Effect on the Brain: Dr. Richard Johnson
What is the relationship between fructose and Alzheimer’s disease? Does fructose cause inflammation? How does fructose impact blood pressure? What about cancer? What role does fructose have in obesity and diabetes? What role does fiber have in the absorption of fructose? Does how quickly you drink a sugary drink impact how much damage it does to the body?Thank you to our sponsor, InsideTracker. SuperAge listeners get 20% off all products here. Professor, clinician, obesity researcher, and author Richard S. Johnson, MD explains how fructose impacts our health from its role in obesity, diabetes, Alzheimer’s, cancer, blood pressure, and more. And David asks the question: can we still eat fruit and be healthy?! Dr. Johnson explains.“Natural fruits are good but don’t get that big bowl of grapes when you’re watching TV and eat the whole thing because then you will be activating the switch.” “If I took a soft drink and I just took one sip every 10 minutes, and I took two hours to drink it, it would be a calorie, it wouldn’t really be more than that. But if I took that soft drink and I drank it, especially on an empty stomach, and just guzzled it down, it would be a big, big activator.”“We know that foods like bread, rice, and potatoes increase our risk for obesity.” “When you eat fructose, the first thing it does is make you hungry, make you thirsty, and it makes you want to forage for food.” “People who are overweight or obese are at increased risk for certain types of cancer. Breast cancer is higher for women who are overweight, colon cancer, liver cancer, and pancreatic cancer. It’s been known that these cancer cells like to grow in the presence of fructose.” Listen to the SuperAge podcast wherever you get your pods.Call in to the podcast and have your question answered on air: 801-871-5291Connect with Dr. Richard Johnson: WebsiteInstagram"Nature Wants Us to be Fat" BookSay hi to the AGEIST team!

He shares everything we need to know about blood pressure from how to treat and prevent high blood pressure, what lifestyle behaviors are contributing factors, the impact of salt, whether we should be taking baby aspirin, and more. “Blood pressure can have a devastating effect on our health when it’s not treated well.” “High blood pressure is the second biggest contributor to the number one cause of death and disability which is heart disease. It also is the primary contributor to stroke and the second strongest factor for kidney failure, as well as diabetes.” “We don’t need to spend another dime on research to understand how to best treat high blood pressure. And yet, this condition, which kind of flies under the radar from doctors and from patients, accounts for 1,100 deaths a day in the United States. 1,100 preventable deaths a day.” “People that are over the age of 74, 85% of them have high blood pressure.” “In my estimation, about 75% of blood pressure can be treated and even mostly cured without medications.” “I’ve come to have an amazing amount of respect for how impactful stress is for a lot of people and for many it is the primary driver of their blood pressure, of their heart disease, of their weight issues. They can’t get where they need to go until they figure out how to manage stress better.” “Afib is an epidemic now in the country. It’s the number one heart rhythm problem cardiologists deal with. Any cardiologist that works in a hospital will tell you that they are overrun by people with Afib.” Listen to the SuperAge podcast wherever you get your pods.

They need to be in balance with omega-6s because if they aren’t, you’ll have inflammatory systems that run out of control.” “Try to avoid all the trans fats, limit your saturated fats, and you’ll be a lot more healthy than the run-of-the-mill person.” “Generally speaking, if you haven’t taken an omega-3 supplement, you are likely deficient.” “EPA and DHA — these powerful omega-3s are so involved with our brain health, they’re so involved with our emotional health, also. So there are claims you can make around EPA with regard to impacting mood health.” “Too much of almost anything can be a bad thing. So be reasonable and be balanced.” Listen to the SuperAge podcast wherever you get your pods.

The difference between traditional saunas & infrared saunas00:57:29 Dr. Scott's final advice on getting healthy“The bad news is that if you live now in the world, your gut is going to be screwed up in some way.” “Salt in water allows that water to get absorbed through your intestinal lumen, through your GI tract into your body. Without salt, some water gets absorbed but a lot of it doesn’t.” “Your brain takes up 20% of your oxygen at all times so it’s a hugely metabolic organ.” “If you’ve been cognitively on all day and then you go directly to workout at the gym, that’s a huge stress on your body.” “After you come out of the cold, you get this reflex vasodilation, you get all this new blood going to your periphery. As a result of that, you feel and get this blood flow to your tissues that you may not have been getting before, especially areas that had been inflamed, areas that have been injured, areas that have been hurting like joints.” “The fantastic thing about cold is that it’s a fantastic way to train your fear response because the first 30 seconds you feel like you’re going to die. Your body is doing everything it possibly can to tell you to get the F out of the water or out of the cold. But if you can go past that, and you can, that’s when your body gets to this blissful state of peace.” “For people who can’t exercise because they have arthritis or they have other joint or mobility issues, you can use a high heat sauna and see significant benefit in that capacity.” “High heat sauna is exercise, infrared is more recovery.”Listen to the SuperAge podcast wherever you get your pods.

That’s a terrible thing in and of itself but when we realize that most of that heart disease is preventable with pretty simple interventions, it makes it even more tragic.” “The biggest problem in healthcare is that about 60% of us have diseases that are preventable and oftentimes curable, we’re just not doing that.”“87.8% of adults in the United States have at least one sign of cardiometabolic disease. And even more shocking, 78% of teenagers had at least one sign of cardiometabolic disease.” “People don’t resist change, they resist being changed.” “If your strategy as a doctor is to say ‘You need to exercise, lose weight, eat better, and quit smoking and I’ll see you in 3 months,’ we can’t be surprised that in 3 months, our patients haven’t changed.”“If somebody is not losing the weight that they want to lose, they’re eating well, they’re being active, and they’re still not losing that weight, I almost universally will say it’s one of three things. 1. They’re not sleeping well. 2. Their stress levels are through the roof and they’re not managing that well. 3. Insulin resistance. They’re not handling glucose well.” “One benefit leads to another benefit. You start exercising so then you sleep better which makes your stress levels better.” Connect with Dr. Hurst:WebsiteSay hi to the AGEIST team!

Why Do Marriages End?: Mark Goulston
In this information-dense episode, we learn several masterful points on how to relate better to all those around us. How can we become better listeners? Why do marriages end? What is the difference between feeling felt vs feeling understood? What are the gender differences when it comes to emotional intimacy? How do you properly respond to your partner’s emotions? Why don’t we understand how powerful disappointment can be in our lives? In this re-play episode, we are featuring one of the most popular podcasts we have done. Dr. Mark Goulston, psychiatrist and author, joins us on the SuperAge podcast to share his insights on these questions. Dr. Mark Goulston dropped out of medical school twice due to depression. After a school counselor believed in him and gave him another chance, he finished medical school and wanted to pay forward what that counselor gave him. That is exactly what he is doing with his current practice. Dr. Goulston uses his empathetic personality and ability to listen to navigate his patients' issues from marriages to eating disorders to strained parent-child relationships to suicide.Thank you to our sponsor InsideTracker. SuperAge listeners get 20% off all products here. What you will learn in this episode: How empathy and the ability to listen can help strengthen our relationshipsWhy some marriages endWhy strong personalities may have a more difficult time with emotionally intimate relationships, and how to overcome that The power of feeling felt vs feeling understood How to respond to your partner’s emotions“Marriages don’t end because we stop loving each other, but because we stop feeling liked by each other.” “Alpha energy is great for success. It’s not good for closeness. You know, it’s good to have alpha energy. You can build something, you can build a business, you can grow it, you can sell it, you can do whatever, but it’s not that good for emotional intimacy.” “One of the reasons women will say ‘Don’t give me advice or solutions’ is because when they’re sharing something, they want to just feel less alone in the feeling, they want to feel felt by you, because if they feel felt by you, their oxytocin goes up, their cortisol goes down, their blood flow goes up to their brain, and then they can give themselves the advice they need.” Listen to the SuperAge podcast wherever you get your pods.
