I ride a bike a lot so much my doctor is impressed with my cholesterol levels. Even the coffee I make at home all of the makers I use pass the oil through to the coffee, which makes the coffee taste better...in my opinion, some don't like the stronger flavor that the oil makes the coffee. I use a Bialetti Brikka Moka pot, Vietnamese Phin, Turkish Ibrik, Cafelat Robot espresso maker, and a Hario V60 Switch. The Hario is normally used with a paper filter which will take out most of the oil, but I switched to a cloth filter so the oil will pass through and into my coffee! Those coffee things I have make European size cups, which is a lot different than American size cups. The Moka pot makes the equivalent of 2 to 3 shots of espresso, as does the Phin, the Ibrik and the espresso maker, The Hario is their smallest 02 size, it makes about 4 to 5 shot sizes equivalent of espresso.
I'm 73 years old I eat meat too without any reservations...except when bicycle camping then I can't take meat, but sometimes if I get a sale price, I'll take beef jerky, (I probably need to buy a dehydrator and make my own Jerky, the price for Jerky is stupidly high).
I do believe that genetics plays a role in whether or not a person is more susceptible to cholesterol levels, but I do know for a fact that regular cardio exercise can be a huge help in maintaining healthy cholesterol levels even if your genetics predispose you to have high cholesterol. Regular cardio will also help with keeping blood pressure and blood sugar levels at healthy levels, and it keeps you moving which is good the older we get.
I've been riding a bike for about 50 years, before that I ran a lot 6 to 8 miles every night, but one day I had a tinge of pain in one of my knees and decided to try something different so as not to stress out a knee before I even turned 23! After I retired, I started going to the gym to add weight training, before I retired, I didn't have time to do both, so only did cycling. My problem as I aged is arthritis pain when I ride and push weight at the gym, it's in my hands and one foot, I just keep riding and pushing weight regardless, it's just pain, it calms down after I get home and rest, the pain is always there to some degree depending on weather, but it peaks when cycling but some days are worse than others. If I stay away from sugar that arthritis pain isn't as intense, so I try to limit my sugar intake, but being human sometimes I indulge myself, LOL!!
