Are strawberries good for your heart?

Strawberries, like all berries, are high in antioxidants, which is great news for your heart! Even better, because strawberries are one of the most eaten, and most easily obtained of the berries in the US.

Strawberries have also been studied extensively for their health benefits, and when it comes to heart health, they definitely should make the cut in your diet! Strawberries are probably most widely known for their vitamin C content – 1 cup of strawberry halves contains 150% of your daily value! But strawberries also contain manganese, iodine, magnesium, copper, iron, and phosphorus, and, to a lesser extent, thiamine, riboflavin, niacin, vitamin B6, vitamin A, vitamin E and vitamin K. Strawberries even have one of the highest folate contents among fruit (9% per 1 cup serving)! (1)

Studies are a bit split on strawberries’ effects on inflammation, with more studies showing strawberries lower inflammatory markers than don’t. Studies have also reported a positive effect on blood lipid size distribution, and decreases in blood pressure and artery stiffness (2). Sounds like a good little fighter to have in your heart health corner!

FAQs and Substitutions

Can I use flax instead of chia seeds?

Normally, the answer is ‘yes’. But in this case, flax seeds won’t work the same. Chia seeds have an outer coating that absorb water and create a gel-like consistency. This makes them ideal for thickening foods like jam and pudding.

If you don’t have chia seeds, you could mix a little cornstarch or arrowroot powder with cold water, and slowly add it to the simmering strawberries until it reaches the consistency you like. I haven’t tested this method, so I can’t recommend amounts, but if you try it, let me know in the comments how it works, and how much you use!

Can I use another fruit besides strawberries?

Yep! This recipe will work with most any fruit! If you have a fruit that doesn’t have larger seeds (like the strawberries do) use ground chia seeds for a smoother jam.

This jam is too chunky for me! How can I fix that?

I get it. Not everyone loves a chunky jam. If that’s you, once your jam cools, pour it into your food processor or blender and blitz it until it’s how you like it!

Can I can this sugar free strawberry chia jam?

This recipe can be canned, but I am by no means a canning expert. Be sure to follow best canning practices from the National Center for Home Food Preservation.

Ingredients

  • 1 lb Strawberries washed and tops removed if fresh, thawed if frozen
  • 2 Tbsp Chia Seeds
  • 1 tsp Lemon Juice
  • (optional) 1-2 Tbsp Honey or sweetener of choice

Instructions

  1. Place strawberries into a medium sized pot, and cook over medium heat, mashing with a potato masher as they cook.
  2. Bring to a simmer, and cook about 5-10 minutes, continuing to stir and mash.
  3. Remove from heat, and stir in chia seeds and lemon juice.
  4. Taste, and add sweetener only if needed (ripe strawberries shouldn’t need any, but if they aren’t in season you may find you need some sweetener).
  5. Cool to room temperature before transferring to jars or an airtight container and refrigerate.
  6. Will last refrigerated for about 7 days. Can be frozen up to 6 months.

Recipe Notes

Note: The jam will thicken as it cools. It takes a bit of time for the chia seeds to absorb the extra liquid.
