What My Hospital Check-Up Taught Me About Nutrition
From laboratory results to a small change in my kitchen
When I received my results from Bangkok Hospital in Hua Hin after my September 2024 check-up, I did not panic.
I had been eating largely plant-based food for decades. I felt that my lifestyle was quite different from that of the average person, and I was more concerned about the consequences of eating too richly than about eating too simply. So, at first, I was not particularly alarmed by the nutrient shortfalls reported in my results.
That was my thinking at the time. Laboratory reference ranges are based on groups of healthy people, but they still provide useful information for individuals. A different lifestyle does not automatically make a low result harmless. Results need to be interpreted in their medical context.[1]
About a year later, I began using ChatGPT. An idea occurred to me: why not enter my results and ask how I could improve my nutritional intake using only plant-based food?
The answer surprised me. Among the suggestions were more nuts and seeds, particularly pumpkin seeds, sunflower seeds, and flaxseed.
Until then, I had mostly thought of seeds as snacks. I had never really given them a serious place in my daily nutrition. Now I was eager to try.
Two tablespoons and a new habit
Once a week, I ground my seeds, put them in an airtight container in the refrigerator, and took two tablespoons every morning.
After about two weeks, I noticed that my nails seemed to grow much faster. The change was temporary, but it caught my attention.
When I asked ChatGPT to look at the faster nail growth from a traditional Chinese medicine perspective, it suggested a connection with improved kidney function. That made me happy, although it was an interpretation rather than a medically confirmed improvement. Kidney function is assessed using blood and urine tests; nail growth cannot establish that.[2]
After about a month, I also felt that my legs were becoming stronger. That was another encouraging observation.
These were changes I noticed after starting the routine. I cannot say that the seeds caused them, or that they proved my nutrient shortfalls had been corrected. That would require appropriate follow-up testing. But they gave me a reason to pay more attention to foods I had previously overlooked.
How I prepare my seeds now
My preparation routine has changed since that first experiment.
I now grind pumpkin and sunflower seeds together, making enough for about one week and keeping the mixture in an airtight container in the refrigerator.
I prepare flaxseed separately, grinding a single portion and eating it immediately. This is my way of keeping it fresh. Ground flaxseed can also be stored properly in the refrigerator or freezer; it does not have to be eaten immediately after grinding.[3]
For me, the important thing is having a simple routine that I can maintain.
Why I became interested in timing
Later, I tried taking my seeds in the evening, around 7 p.m. I felt that this suited me better than taking them in the morning.
That experience sparked my interest in circadian rhythms: the daily biological rhythms that influence many functions in our bodies, including metabolism.[4]
I liked the idea of providing building blocks ahead of a night's rest. But that is my interpretation of the experience, rather than a demonstrated explanation. Research on circadian rhythms does not establish that eating this seed mixture at 7 p.m. improves overnight repair or works better for everyone.
For now, evening is my personal preference.
What I took away from the experience
The biggest change was in how I looked at my food.
A diet can feel healthy and still deserve a closer look. My hospital results gave me questions to ask, and ChatGPT helped me generate ideas to investigate. Its suggestions were a starting point, rather than a medical assessment.
I had spent years choosing my food carefully, yet a few ordinary seeds still had something to teach me.
They moved from the snack category into my everyday meals—and that small change made me more curious about what my body needs.
This article describes my personal experience. The changes I noticed do not establish cause and effect or replace medical interpretation of laboratory results.
