Short after an unusually early run today I measured my heart rate, oxigen and stress levels, and have chosen my mood - happy. And then I have noticed I was apparently quite stressed :)

I found a very big papaya in a local growers store, around 13 inches long. And it was good too.

It seems to be a grapefruit season, so I've been buying them in big bags and making daily juice out of three large grapefruits. It takes a couple of minutes with this simple tool - I used to have one made of stainless steel - but the hard plastic works well too.
Grapefruit juice is so delicious, make some!


Today I went for a short run,  five kilometers, first time after many days of rain. My heart rate (61 bpm) and SpO2 measurements are good.

Heart rate 63 by the end of the day.

SpO2 is 100%.

SpO2 stands for peripheral capillary oxygen saturation, an estimate of the amount of oxygen in the blood.

It is the percentage of oxygenated haemoglobin (haemoglobin containing oxygen) compared to the total amount of haemoglobin in the blood.

In this third week of the year my health app gave me a report with this numbers:

Avg. carb intake 156.7 g
Avg. fat intake 37.8 g
Avg. protein intake 22.9 g

Avg. carb percentage 59.0%
Avg. fat percentage 32.0%
Avg. protein percentage 9.0%

I did forget to log a couple of days and missed a few fruits, but the average numbers should be close to real.  I ate more seeds this week than I do usually. It had been cold.

Winter berry choices: organic raspberries and wild blueberries.

Vitamin C

Vitamin C, or L-ascorbic acid, or ascorbate, is an essential nutrient for humans, a water-soluble vitamin. Humans, unlike most animals, are unable to synthesize vitamin C, so it is an essential dietary component. 

  • Vitamin C is required for the biosynthesis of collagen (an essential component of connective tissue), L-carnitine, and certain neurotransmitters, it is also involved in protein metabolism.
  • Vitamin C is also an important physiological antioxidant and has been shown to regenerate other antioxidants within the body, including alpha-tocopherol (vitamin E). Vitamin C regenerates vitamin E by reducing vitamin E radicals formed when vitamin E scavenges the oxygen radicals. 
  • Vitamin C plays an important role in immune function and improves the absorption of nonheme iron, the form of iron present in plant-based foods.

Approximately 70%–90% of vitamin C is absorbed at moderate intakes of 30–180 mg a day. At doses above 1 g a day, absorption falls to less than 50% and absorbed, unmetabolized ascorbic acid is excreted in the urine. 

Insufficient vitamin C intake causes scurvy, which is characterized by fatigue or lassitude, connective tissue weakness, and capillary fragility.

Cells accumulate vitamin C. The total body content of vitamin C ranges from 300 mg (at near scurvy) to about 2 g.

  • High levels of vitamin C are maintained in cells and tissues, and are highest in leukocytes (white blood cells), eyes, adrenal glands, pituitary gland, and brain.
  • Relatively low levels of vitamin C are found in extracellular fluids, such as plasma, red blood cells, and saliva.
