Assuming you have a normal diet are the recipes it generates pretty healthy?
In my deep dive into the world of low carb, I learned that elevated levels of fructose/uric acid reduce the synthesis of nitric oxide, a known vasodilator, among other mechanisms (did you know that the explosive nitroglycerin is an effective vasodilator?). High blood pressure is reversible by reducing the amount of insulin spikes and ingested simple sugars, and low carb is the most effective method.
Yet most apps tend to pride themselves in "medically approved science here!", which means the usual story of eating less meat and saturated fat, and exercising more. "Leafy vegetables!"
The problem is that medically approved science that your GP offers tends to be about 25 years out of date, so we're at least a generation away before we have apps that tell you to stop eating bread, cereals for breakfast and heaping bowls of fruit, but instead eating real, non-sugary foods and not to shy away from saturated fat.
Now I am 50kg overweight than my first hypertensive diagnosis in my early 20s, and I have better blood pressure in about 2 weeks of eating fewer carbs than I did at the time when I was fit as a trout, but with tight arteries.
And don't get me started on cholesterol and statins, because I'll be here all day.
A link to get you started, if you want to base your app on up-to-date research: https://youtu.be/KlHPmJTihBc
tl;dr: statins don't do much apart from reducing a single metric of an entire systemic disorder, and have terrible side effects, LDL is positively correlated with longevity in healthy subjects, high levels of blood sugar destroy a "marker" protein on LDL cells, they stop being recognised and reabsorbed by the liver but instead they go and accumulate under artery walls. Atherosclerosis is not caused by dietary fat, but high levels of dietary fat paired with high levels of blood sugar.
In general, high levels of sugar alone are worse by all metrics that high levels of dietary fat, and very recent research seems to suggest mitochondria work better burning fatty acids than glucose (to be clear, the chemical pathway is exactly the same, but fatty acids skip a couple steps and produce fewer free radicals)
What about the type of carbs in oatmeal, those are better right?
People will focus on their individual experience as a proxy for generalizing others way too much.
While there are some universal principles, extremes around eating both bad and eating healthy can be confused with eating simple or eating clean.
If someone has a cashew allergy, the practice of veganism can be life threatening where it’s used so much.
If you come from a certain area of the world, your genetics might be a little more used to benefiting from eating certain things than not, too. A negotiation for might be nice for me but for someone who’s being eating it well for a few generations..
How do you know how to identify healthy foods?
What is a "healthy" food?
My approach: healthier products aren't wrapped and don't have nutrition labels on them.
My goal is to simplify healthy eating and improve nutrition habits.
I asked people outside various grocery stores and most folks do not know how to read nutrition labels nor identify healthy foods. My dad was able to practice some healthier eating habits and get his BP from hypertension to normal.
Please feel to reach out if you have any questions or advice for me. I’m new to this so I appreciate your message.
