Foods High in Magnesium: Eat Smart for a Healthier You

Foods high in magnesium should be an essential item on your grocery list, as magnesium is a mineral that should never be disregarded. Magnesium plays an important part in over 300 metabolic events in the body and is required for muscle and neuron function, blood sugar management, and bone health. Despite its importance, many people do not consume enough magnesium each day. 

Magnesium is vitally important for your body and has a range of health benefits. Without it, your organs will fail to function as they should. Many foods contain a high magnesium content, yet many people don’t get enough of their daily dosage. This is a concern because, without this essential mineral, our body can’t function optimally.

Join us in our investigation into magnesium and the foods that are high in this important mineral. This blog will inform you on how to meet your daily needs naturally and how you can add magnesium easily to your daily healthy diet.

A magnesium supplement may be needed to give you more magnesium to increase your health benefits.

What is Magnesium?

Magnesium is a mineral that plays a role in various chemical reactions in the body. It is also important in the treatment of several health issues, such as stroke, preeclampsia, hypertension, muscle cramps, migraines, and irregular heartbeats or heart rhythms.

Magnesium also helps regulate blood pressure and blood sugar and promotes heart and bone health.

Regulates Blood Pressure

In people with prehypertension, magnesium reduces high blood pressure.This is the case for diastolic blood pressure as well as systolic blood pressure. It does this in two ways:

Preventing Injury to Blood Vessel Walls

Over time, blood vessels may become damaged, making them less flexible and raising blood pressure. Magnesium helps to repair damage and remove substances that cause damage, helping to not just lower blood pressure but also keep it regulated.

Preventing Blood Vessels From Hardening

Calcium starts to build up in blood vessels, causing them to become hard and increasing blood pressure. Magnesium solves this by sticking to the blood vessel walls preventing the calcium from accumulating and keeping blood pressure low.

Blood Sugar Control

Magnesium helps to keep blood sugar regulated. Research shows that magnesium is beneficial in preventing insulin resistance and is beneficial in people who have diabetes. Insulin resistance occurs when the body can’t use the insulin the body produces.

Promotes Heart Health

Magnesium lowers the risk of heart disease by preventing atherosclerosis, the stiffening, and hardening of the arteries. It also keeps blood vessel walls healthy so that oxygen-rich from taking place. Atherosclerosis is the stiffening and hardening of the arteries. It also keeps blood vessel walls healthy, so blood-oxygen-rich blood can flow freely when being transported to the heart.

Avoid saturated fat to promote the lower risk of coronary spasms.

Ensures Bone Health

Magnesium is extremely important for bone health by building and maintaining strong, healthy bones. It works with Vitamin D and calcium to increase bone mineral density and lower the risk of osteoporosis.

If you have low levels of magnesium in your body, magnesium is drawn from the bones because it is needed for so many bodily functions. If this keeps happening then your bones will start to become brittle.

Magnesium Intake

The amount of magnesium required daily varies according to age, gender, and life stage. Due to the fact that the amounts differ according to different factors,  it’s important to know how much you need and stick to it. 

The recommended dietary allowances (RDA) are as follows:

Older Adults (aged 31 and over):

The recommended dietary allowance of magnesium is 420 mg per day for males and 320 mg per day for females.

Adults (aged 19 and up):

The RDA for magnesium is 400 mg per day for men and 310 mg per day for women.

Adolescents (14 to 18 years old):

The recommended daily allowance of magnesium for adolescents is 410 mg for males and 360 mg for females.

Pregnant Women:

The amount needed for pregnant women differs depending on age. Pregnant women under 19 require 400 mg per day, those 19 to 30 need 350 mg a day, and those 31 years and up need 360 mg.

Lactating mothers under 19 years need 360 mg per day, ages 19 to 30 years need 310 mg a day, and 31 years and up need 320 mg per day.

Children (ages 1 to 13 years):

Children aged 1 to 3 need 80 mg per day, children aged 4 to 8 need 130 mg per day, and children aged 9 to 13 need 240 mg per day.

Magnesium Deficiency

Magnesium deficiency is a common but frequently neglected health concern. Early detection of warning signs and symptoms can help to avoid significant health consequences. You may experience abnormal eye movements, nausea, fatigue, vomiting, convulsions, low appetite, muscle contractions, weakness, numbness, and spasms.

Inflammation markers start to increase in the body and can increase the risk of certain cancers, heart disease, diabetes, and osteoporosis.

People who have a higher chance of magnesium deficiency are older people and people who suffer from the following:

  • Celiac disease

  • Kidney disease

  • Crohn’s disease

  • Cancer

  • Parathyroid issues

  • Hypertension

  • Type 2 diabetes

  • Alcohol dependence

Factors Influencing Low Magnesium Absorption

Proton Pump Inhibitors (PPI):

These medications lower stomach acid in people with gastrointestinal diseases. Long-term use of PPIs has the side effect of lowering magnesium absorption in the intestine, which lowers the overall magnesium levels in the body.

Most magnesium is in food, check with your healthcare provider if you need supplements.

Diuretics( Water Pills):

Diuretics, sometimes known as water pills, are substances that help the body get rid of excess fluid by increasing urine production. While they are commonly treat hypertension, heart failure, and some kidney problems, they can also disrupt the body’s electrolyte balance, particularly magnesium levels.

Ways to Improve Absorption

Calcium and Vitamin D

Calcium, vitamin D, and magnesium are all critical minerals that work together to support a variety of biological activities, including bone health, muscle function, and overall metabolic processes.

Vitamin D helps the intestines absorb magnesium more effectively. Adequate vitamin D levels can assist ensure that dietary magnesium is properly absorbed into the bloodstream.

Zinc Dietary Supplement

 While these minerals perform complementary functions, large dosages can compete for absorption in the intestines. If one mineral is ingested in excess compared to the other, the competition may result in deficiencies.

To minimize potential absorption concerns, take zinc and magnesium supplements at different times of the day or use a balanced multivitamin/mineral supplement that contains adequate quantities of both minerals.

Magnesium Supplementation

In powder form magnesium supplements are easier to digest, and therefore, it is recommended to use a powdered form of magnesium, as it can be absorbed better by the body.

Magnesium Supplements

Getting enough magnesium through your diet is enough for most adults. However, there are times when magnesium supplementation is a must. It’s important to note that there are different types of magnesium supplements:

Magnesium Chloride

Used for pre-diabetic conditions and to increase magnesium levels in the body.

Magnesium Oxide

Use to manage constipation and magnesium deficiency.

Magnesium Citrate

For mild cases of constipation, these dietary supplements serve as laxatives.

Too Much Magnesium

Too much magnesium isn’t a good thing; having too much magnesium in your body can be harmful. Milder symptoms include diarrhea, vomiting, muscle weakness, nausea, lethargy, and stomach cramping. If your magnesium intake is extreme, it could lead to magnesium toxicity, which causes irregular heartbeats, chronic diarrhea, and extremely low blood pressure.

Excess magnesium from ingesting foods high in the mineral is expelled by the kidneys, so the risk of overdosing lies with taking a dietary supplement. Although magnesium toxicity is uncommon, it could be life-threatening, so it is important to ensure you take the mineral in moderation. Therefore, if you are supplementing with magnesium, ensure it is a reliable brand and the correct dosages.
