16 Food Sources To Get All the Boron You Need!

Foods High In Boron

Micronutrient boron is found in a variety of fresh produce, dried fruits, nuts, beans, and lentils. While there is no RDA for this trace mineral, foods like avocado, raisins, apricots, red grapes, celery, carrots, and broccoli can help you meet your requirements. So eat up!

If you are trying to raise your dietary intake of trace mineral boron, it might seem like a tough ask at first. But this lesser-known micronutrient is surprisingly common, found in foods that you probably already have in your diet or have at least tried at some point. So increasing that boron intake really doesn’t have to take too much effort. Just be conscious of which foods are the best way to get to your targets and you’ll do just fine!

Boron: Involved In Bone Health, Memory, Wound Healing And More

Boron is a nutrient that has many benefits but isn’t as well known as minerals like iron or calcium. Yet, it is essential for the healthy development of your bones, can help with wound healing, cuts inflammation, has antioxidant benefits, and may even improve cognitive performance and help memory in seniors. It even impacts how well your body can use vitamin D and hormones like testosterone and estrogen. It is also being applied therapeutically for cancers of the lung, cervix, and prostate as well as multiple and non-Hodgkin’s lymphoma.1 Reason enough to sit up and pay attention to this diminutive micronutrient!

No RDA But Doses Of 3 Mg/d Plus May Be Beneficial

While there isn’t a recommended daily intake level for boron, the upper intake level (UL) for adults is around 20 milligrams per day (mg/d). For pregnant women and nursing mothers, this limit is set at 17 mg/d. This merely sets an upper limit to what your intake should be but doesn’t suggest how much to have every day.2 That said, most research shows health benefits from boron when it is consumed at doses of 3 mg/d or more.3 By some estimates, the average dietary intake of boron in the United States is in the region of 1.7–7.0 mg/d.4

There are dozens of foods that contain boron, yet as one early study showed, the typical American diet taps those which are not necessarily the richest sources. For instance, at the time of the study in 1999, milk and coffee contributed to 12% of the total boron consumed in the diet. But individually, they are hardly the richest dietary sources. For that, you’re better off turning to other foods we’ve listed here.5

Here’s a look at some of the best dietary sources of boron. Some estimates come from the country’s standard Food Processor databases which have historically collated data on nutrient content of ingredients and various foods. However, researchers caution that these may overestimate the quantity of boron in the food. An actual chemical analysis of foods, when undertaken by researchers, have found the numbers to be slightly lower.6 Where available, the data for the chemical analysis results have also been included and these may be closer to the actual numbers. That said, the following foods are still the best dietary sources of boron, regardless of whether they actually contain boron at the higher or lower estimates.

1. Avocado

A cup of cubed avocado will contain around 3.09 mg of boron.

A cup of cubed avocado will contain around 3.09 mg of boron according to database estimates while the actual chemical analysis pegs this at 2.15 mg of boron.7 Either way, this is a rich source of the micronutrient and well worth adding to your meal plan. Whether you whizz it up into creamy smoothies, make chocolate avocado puddings with it, or have it on toast or in dips and guacamole, you are sure to enjoy this mealtime addition.

2. Beans, Peas, and Legumes

A cup of red kidney beans packs in 2.48 mg of boron.

Lentils, legumes, and beans are a rich source of boron and are often already part of most regular main meals, especially for vegans. Even if you are normally more of a fish or meat eater, these versatile plant protein sources are a smart addition to the diet for their boron content. A cup of red kidney beans packs in 2.48 mg of boron. A cup of lentils has 1.47 mg of the trace mineral.8 Chickpeas have about 1.05 mg of boron to the cup.9

Beans and lentil options are endless. You could whip up a delicious spice infused curry, a hot Mexican chili, a healthy bean and broccoli taco, or even a warming soup inspired by Tuscan recipes from Italy.

3. Dried Fruit

An ounce of dried apricots will give you around 0.59 mg of boron.

Dried fruit is a handy on-the-go food source that you can incorporate into recipes for some sweetness and texture. An ounce of raisins has 1.28 mg of boron, making it a great source of the micronutrient. An ounce of dried apricots, on the other hand, will give you around 0.59 mg of boron. An ounce of prunes contains 0.53 mg.10

Use them in your muffins or cookies or add them to oatmeal, granola, or even pies. You could also make rice or bread puddings which set the tart sweetness from these dried fruits against the creamy smoothness of the milky dish. You might even enjoy them in your savory salads, couscous, or tagines.

4. Nuts

An ounce of almonds has 0.8 mg of boron.

A 2 tablespoon serving of peanut butter (30 gm), is estimated to have 0.58 mg of boron by software databases while chemical analysis pegs the number at a more modest 0.18 mg. Either way, it is a delicious and easy way to get in the nutrient. 11

An ounce of almonds has 0.8 mg of boron. A similar portion of hazelnuts contains 0.79 mg, Brazil nuts 0.49 mg, walnuts 0.46 mg, and cashews 0.33 mg of the mineral. 12 This makes nuts another easy way to ramp up the intake of boron. As with dried fruit, you could use them to add crunch to salads, home baked bread, cookies or brownies, or a simple bowl of porridge. Traditional Iranian style pilafs and other Middle Eastern recipes use nuts as a garnish and textural element to perfection.

5. Peaches

A cup of peaches contains 0.78 mg of boron.

You can also enjoy peaches whenever they’re available – a cup of them contains 0.78 mg of boron.13 Simply eat your peaches plain or roast or grill them and sprinkle over some spices and nuts.

They also work very well in salads and as a foil to tuna and poultry.

If you find it easier to drink up your nutrients, grape juice could do the trick too! A cup of the juice gives you about 0.85 mg of boron as per chemical analysis.15

7. Wine, Beer, And Cider

 5 fluid ounces of Shiraz Cabernet wine has 1.29 mg of boron.

While data on the content in cider and beer aren’t widely available, a standard 5 fluid ounces of Shiraz Cabernet wine will deliver around 1.29 mg of boron. Chemical analysis puts this number closer to 0.54 mg.16
