According to the US Department of Agriculture, every 100g of cooked skinless chicken thigh contains 24.6g of protein, and 100g of eggs contains 12.6g of protein. Fun fact, about 60-65% of the egg's weight comes from the egg white and a 2023 study found that "protein content in the egg white is 10.9% w/w and 15.9% w/w in the egg yolk" ("w/w" meaning "weight on weight, a measurement used in chemistry)... so there is slightly more protein in the yolk, but not by much.
One chicken thigh varies in weight depending on size, of course. I was in the supermarket today and chicken thighs were sold in packs of two, which ranged from 296g per pack to 432g per pack. So one thigh is about 150g to maybe 215g depending on size. I usually have one thigh with lunch every day (in addition to vegetables and a bit of rice). So that would be at least 36.9g of protein at the lower estimate of weight.
Based on my research, it seems that Grade A or large eggs in Malaysia are about 60-70g each depending on supplier. So if you eat 2 eggs a day, you're getting between 15.12g to 17.64g of protein, if my calculations are correct. Let's go with the lower number, to be conservative. So one chicken thigh + 2 eggs = at least 52g of protein a day.
General protein intake recommendations are at least 0.8g of protein daily per kg of body weight to prevent deficiency. I definitely weigh more than 41.6kg. Hmmm. The Mayo Clinic adds that people over 40 or 50 need more protein to prevent losing muscle mass, also known as sarcopenia, which tends to come with aging (I assume this applies to sedentary and non-athletic people; the article didn't specify). They recommend 1-1.2 g of protein per kg.
Nutrient intake is tricky because it is measured by the weight of the food, which makes sense from a scientific viewpoint, but when we buy food we generally think of bunches or pieces (biji!), not weight. The World Health Organisation recommends consuming 400g of fruits and vegetables daily, but what does 400g even look like? One pack of shiitake mushrooms from Jaya or Village Grocer is 150g and one pack of baby spinach leaves is 100g, I know that much. I definitely cannot eat a whole pack of mushrooms and baby spinach leaves in a day. How could anyone possibly reach the 400g requirement?
I also don't know how many grams four slices of papaya or quarter of a dragon fruit are -- things that I quite often eat. Working in the dark here.
