How many calories are in poppy seeds?

Poppy seeds are calorie-dense at 525 calories per 100g, but you rarely eat much. A teaspoon is only 16 calories and a tablespoon about 47, so the small amounts sprinkled on a bagel or stirred into dressing barely move your daily total.

Are poppy seeds high in calcium?

Exceptionally so. Poppy seeds contain 1438mg of calcium per 100g, one of the richest plant sources around and more than a cup of milk per ounce. Even a tablespoon adds roughly 130mg, which supports bone health on a dairy-free diet.

Are poppy seeds good for you?

Yes, in small amounts they are nutrient-packed. Beyond 1438mg of calcium per 100g, they supply 9.8mg of iron, 719mg of potassium, and 19.5g of fiber. The 41.6g of fat is mostly unsaturated, the heart-healthy kind.

Do poppy seeds have protein?

Poppy seeds carry 18g of protein per 100g, solid for a seed, though a typical tablespoon only delivers about 1.6g. They make a better mineral and fiber booster than a primary protein source.

Are poppy seeds keto-friendly?

Poppy seeds work well on keto because their fiber is so high. Of the 28.1g total carbs per 100g, 19.5g is fiber, leaving just 8.6g net carbs, and a real-world tablespoon adds under 1g net carb to your day.

Can poppy seeds make you fail a drug test?

Possibly. Poppy seeds can carry trace opium alkaloids that may trigger a positive result on a sensitive opiate test for a day or two after eating a lot of them. This is about residue on the seeds, not the 525 calories or nutrition, and culinary amounts pose no health risk.

How should I store poppy seeds?

Because of their 41.6g fat content per 100g, poppy seeds can turn rancid. Keep them in an airtight container in the fridge or freezer, where they last up to a year, instead of a warm pantry shelf.
