How should I track Granola bar, oats and honey?
Granola bar, oats and honey is high in magnesium. The most reliable way to track Granola bar, oats and honey is with a kitchen scale. Research consistently shows that visual portion estimation is off by 20–50% for most food types (Almiron-Roig et al., Appetite 2013), and even trained dietitians make errors when eyeballing portions. A quick weigh takes seconds and eliminates the biggest source of tracking inaccuracy. If you are unsure about a portion size, it is better to log slightly more rather than less — a meta-analysis (Wehling & Lusher, Am J Clin Nutr 2021) found that underreporting is the most common error, averaging 25–30% of actual intake.
