Well dang it, I failed to mention cancer. Amazing that even if you're a strong fit guy, cancer can take you down to nothing.
He developed a spot on his toe. Amputated then a year later showed up in his brain. Treated and cancer free for another 6 months. Then it reappeared throughout his organs, spread all over.
Guy went from beautiful racing bikes to a recumbent not being able to balance. Good looking Superman type to a frail looking Grey haired old looking guy within a year. Only 2 months younger than I and at 52 he looked 70 before passing. Really sad because he was a great guy.
As far as eating, I don't do gels and [censored] like that. On a usual 40 miles I don't eat anything other than a decent breakfast. 2 eggs and a slice of bread and a bottle of electrolytes.
60 miles, I will have a small granola bar.
100 miles, a nice turkey sandwich if I can find one after 65. If I know nothing is available, I will wrap a p and Jin foil if the weather isn't too hot.
I agree about eating too much on rides. I have ridden with people who take in 2 or 3 gels on a 20 mile ride. Some people even more.
As far as electrolytes, I have read and practice one article I found that made sense to me. I drink water the first hour then electrolytes for the remainder of the ride.
A longer ride 40 and up, first bottle of water. Second bottle is mixed so at break, I mix a liquid iv packet to refresh my electrolyte bottle. 😄
Sorry to hear about your friend. Many of my relatives have also died of cancer and risk runs in our genes.
Simple sugars like that in gels although easy to digest in most circumstances is not the same during vigorous exercise because the blood flow is being diverted to the legs (in cycling) away from organs that are less critical to workout performance like the digestive system. The sugar would stay longer in the gut could disrupt the bacteria colony and usually, sweeter stuff in the gut encourages bad bacteria strains to move in and compromise the immune system.
That sugar staying longer can also fuel malignant cells that has formed in the gut. Usually, the immune system can destroy malignant cells if they form in the very early stages in healthy individuals but if the immune system has been compromised and the malignant cells are strong with abundant supply of simple sugars then it's going to become a big problem.
The same can happen to a person who doesn't exercise, who is sedentary but eats plenty of simple sugars.
Although simple sugars isn't totally bad. It's totally okay for active individuals like you and me to eat simple sugars after workouts. Eating simple sugars before a workout is also okay as long as there's enough time between the intake and the start of the workout so the sugar has been fully absorbed by the blood.
It's also okay to eat simple sugars in between rides if you're going to stop and wait some time after the meal to resume the ride. If you must eat during the ride, rice-based unsweetened snacks like rice crackers are safer. They can be salted for flavor and electrolytes. I used to make my own rice crackers for rides and it's a good-tasting, filling snack for rides that won't ruin your digestion but it's really safer if you don't eat anything at all during rides.
