I eat 66 grams of flaxseed per day. (I eat it with yogurt in two batches. For each batch, I weigh out 33 g of whole flaxseeds then grind them.) Not everyone has a scale, so I found that 100 ml of whole flaxseed weighs about 64 grams. Assuming 1 tablespoon = 15 ml, that’s 6.9 tablespoons/day whole flaxseed. If you are interested in weight/volume conversion, that’s 9.5 g of whole flaxseed = 1 tablespoon. I checked this using two different volume spoons and a scale that matches another scale.
This website says there are 15.02 g of whole flaxseed in a tablespoon. I am measuring brown flaxseeds. Perhaps their golden flaxseeds are smaller and therefore more dense. The overprecision suggests this shouldn’t be trusted.
This website says there 14.17 g of “dry” flaxseed in a tablespoon. Again with the overprecision.
According to this website, there are 7.5 g of whole flaxseed in a tablespoon.
