Most Australians consume less than half the recommended quantity of wholegrain foods, and too much refined grain cereal food. At least two thirds of grain foods eaten should be wholegrain. Read more on NHMRC — National Health and Medical Research Council website.

There is strong evidence that for each serve of vegetables eaten each day the risk of coronary heart disease is reduced even further! Also, by eating vegetables, especially colourful vegetables, there is a reduced risk of stroke and weight gain. Nuts provide protein and are a source of dietary fibre as well as contributing many vitamins and minerals.

Many studies show nuts are beneficial to health, especially heart health. Read more on myDr website. Read more on palliAGED website.

Nonfat or low-fat Greek yogurt is a great source of magnesium: Expect roughly Greek yogurt is also high in protein Past research suggests that high-protein meals can make you feel fuller longer, which may help you eat fewer calories overall, ultimately leading to weight loss.

Pair yogurt with a fiber-rich fruit for an easy, healthy breakfast. Whole grains such as brown rice are salubrious in more ways than one. For instance, they can help support healthy cholesterol levels , as the American Heart Association notes, and they can help keep you regular, per the Harvard T.

Chan School of Public Health. One easy way to incorporate more whole grains into your diet is by swapping refined carbs such as white rice for complex sources such as brown rice. And, you guessed it, this food is also a source of magnesium. According to the USDA , one cup of cooked long-grain brown rice provides Additional reporting by Debbie Strong.

For infants from birth to 12 months, the FNB established an AI for magnesium that is equivalent to the mean intake of magnesium in healthy, breastfed infants, with added solid foods for ages 7—12 months.

Magnesium is widely distributed in plant and animal foods and in beverages. Green leafy vegetables, such as spinach, legumes, nuts, seeds, and whole grains, are good sources [ 1 , 3 ]. In general, foods containing dietary fiber provide magnesium.

Magnesium is also added to some breakfast cereals and other fortified foods. Some types of food processing, such as refining grains in ways that remove the nutrient-rich germ and bran, lower magnesium content substantially [ 1 ]. Selected food sources of magnesium are listed in Table 2.

The U. Food and Drug Administration FDA developed DVs to help consumers compare the nutrient contents of foods and dietary supplements within the context of a total diet. The DV for magnesium is mg for adults and children age 4 years and older [ 11 ]. FDA does not require food labels to list magnesium content unless magnesium has been added to the food.

Magnesium supplements are available in a variety of forms, including magnesium oxide, citrate, and chloride [ 2 , 3 ]. The Supplement Facts panel on a dietary supplement label declares the amount of elemental magnesium in the product, not the weight of the entire magnesium-containing compound.

Absorption of magnesium from different kinds of magnesium supplements varies. Forms of magnesium that dissolve well in liquid are more completely absorbed in the gut than less soluble forms [ 2 , 12 ].

Small studies have found that magnesium in the aspartate, citrate, lactate, and chloride forms is absorbed more completely and is more bioavailable than magnesium oxide and magnesium sulfate [ ].

Magnesium is a primary ingredient in some laxatives [ 18 ]. Although such a dose of magnesium is well above the safe upper level, some of the magnesium is not absorbed because of the medication's laxative effect.

Magnesium is also included in some remedies for heartburn and upset stomach due to acid indigestion [ 18 ]. Extra-strength Rolaids, for example, provides 55 mg elemental magnesium as magnesium hydroxide per tablet [ 20 ], although Tums is magnesium free [ 21 ].

Dietary surveys of people in the United States consistently show that many people consume less than recommended amounts of magnesium. In a study using data from NHANES — to assess mineral intakes among adults, average intakes of magnesium from food alone were higher among users of dietary supplements mg for men and mg for women, equal to or slightly exceeding their respective EARs than among nonusers mg for men and for women [ 23 ].

When supplements were included, average total intakes of magnesium were mg for men and mg for women, well above EAR levels. No current data on magnesium status in the United States are available. Determining dietary intake of magnesium is the usual proxy for assessing magnesium status.

NHANES has not determined serum magnesium levels in its participants since [ 24 ], and magnesium is not evaluated in routine electrolyte testing in hospitals and clinics [ 2 ].

Symptomatic magnesium deficiency due to low dietary intake in otherwise-healthy people is uncommon because the kidneys limit urinary excretion of this mineral [ 3 ]. Early signs of magnesium deficiency include loss of appetite, nausea, vomiting, fatigue, and weakness.

As magnesium deficiency worsens, numbness, tingling, muscle contractions and cramps, seizures, personality changes, abnormal heart rhythms, and coronary spasms can occur [ 1 , 2 ]. Severe magnesium deficiency can result in hypocalcemia or hypokalemia low serum calcium or potassium levels, respectively because mineral homeostasis is disrupted [ 2 ].

Magnesium inadequacy can occur when intakes fall below the RDA but are above the amount required to prevent overt deficiency.

The following groups are more likely than others to be at risk of magnesium inadequacy because they typically consume insufficient amounts or they have medical conditions or take medications that reduce magnesium absorption from the gut or increase losses from the body.

The chronic diarrhea and fat malabsorption resulting from Crohn's disease, gluten-sensitive enteropathy celiac disease , and regional enteritis can lead to magnesium depletion over time [ 2 ]. Resection or bypass of the small intestine, especially the ileum, typically leads to malabsorption and magnesium loss [ 2 ].

The magnesium loss appears to be secondary to higher concentrations of glucose in the kidney that increase urine output [ 2 ].

Magnesium deficiency is common in people with chronic alcoholism [ 2 ]. In these individuals, poor dietary intake and nutritional status; gastrointestinal problems, including vomiting, diarrhea, and steatorrhea fatty stools resulting from pancreatitis; renal dysfunction with excess excretion of magnesium into the urine; phosphate depletion; vitamin D deficiency; acute alcoholic ketoacidosis; and hyperaldosteronism secondary to liver disease can all contribute to decreased magnesium status [ 2 , 27 ].

Older adults have lower dietary intakes of magnesium than younger adults [ 21 , 28 ]. In addition, magnesium absorption from the gut decreases and renal magnesium excretion increases with age [ 29 ]. Older adults are also more likely to have chronic diseases or take medications that alter magnesium status, which can increase their risk of magnesium depletion [ 1 , 30 ].

Habitually low intakes of magnesium induce changes in biochemical pathways that can increase the risk of illness over time. This section focuses on four diseases and disorders in which magnesium might be involved: hypertension and cardiovascular disease, type 2 diabetes, osteoporosis, and migraine headaches.

Hypertension is a major risk factor for heart disease and stroke. Studies to date, however, have found that magnesium supplementation lowers blood pressure, at best, to only a small extent.

A meta-analysis of 12 clinical trials found that magnesium supplementation for 8—26 weeks in hypertensive participants resulted in only a small reduction 2.
