A Comprehensive Guide to Folate: The Essential Nutrient for Health

One of the most vital nutrients in our diet is folate. Known as folic acid in its synthetic form used in supplements and fortified foods, this B-vitamin plays a fundamental role in our health, right down to our very cells.

Its functions are critical for survival, including:

• The synthesis and repair of DNA and RNA.
• The production of healthy red blood cells.
• The conversion of the amino acid homocysteine to methionine, a process vital for cardiovascular health.

In food, folate exists in various forms, such as 5-Methyltetrahydrofolate. While the names are complex, the message is simple: a consistent dietary intake of folate is essential for the proper functioning of the human body.

Recommended Intake and Food Equivalents

In Australia, the Recommended Dietary Intake (RDI) for adults is 400 micrograms (µg) per day. This requirement increases significantly for women who are planning a pregnancy or are pregnant.

To achieve 100% of the adult RDI from a single food source, you could consume any one of the following:

• 30g of Chicken, Duck, or Goose Liver (cooked)
• 60g of Mung Beans (uncooked)
• 100g of Red Kidney Beans (uncooked)
• 100g of Flowering Choy Sum (raw)
• 150g of Flowering Choy Sum (cooked)
• Less than 20g of Vegemite
• ~100g of a fortified Wholegrain Breakfast Cereal
• ~4 slices of fortified White or Brown Bread

Dietary Sources and Bioavailability

A key factor to understand is bioavailability—the amount of a nutrient your body can absorb and use. The bioavailability of natural food folate is around 50-60%, whereas the folic acid in fortified foods or supplements is higher, at approximately 85%.

While a well-balanced diet should provide adequate folate, it’s crucial to be mindful of your intake. A diet consistently rich in whole foods is the best strategy. This includes a wide variety of dark green leafy vegetables, legumes, fruit, nuts, and eggs. After all, food tastes better than pills, and at iSupportChef, we love it when you get your greens!

Top Tier Food Sources of Folate:

• Liver: Chicken, beef, and lamb liver are nutritional powerhouses of folate.
• Seaweed: Nori seaweed is an excellent source.
• Asian Greens: Mizuna and Tatsoi are particularly rich in folate.
• Legumes: Mung beans, black-eyed peas, red kidney beans, and broad beans.
• Leafy Greens: English spinach is a classic and potent source.
• Fortified Foods: Vegemite, fortified breakfast cereals, and bread.

Understanding Folate Fortification in Australia

If you consume bread or certain cereals, you are likely getting a regular dose of folic acid. Since 2009, Australia has had a mandatory fortification policy requiring non-organic wheat flour used for bread-making to be fortified with folic acid. This public health measure was introduced primarily to reduce the incidence of Neural Tube Defects in newborns.

While bread fortification is mandatory, its addition to breakfast cereals is voluntary, so it’s always wise to check the nutrition label. Note that organic wheat flour is exempt from mandatory fortification.

The Critical Health Impacts of Folate

Adequate folate intake is linked to a range of profound health outcomes.

Its most critical role is in the prevention of Neural Tube Defects (NTDs), such as spina bifida, in developing babies. For this reason, it is imperative that women planning a pregnancy ensure their folate levels are sufficient before conception and throughout the first trimester.

Furthermore, ongoing research has indicated that adequate folate intake may help minimise the risk of other conditions, including certain cardiovascular diseases, Alzheimer’s disease, and some cancers. It’s important to note that lifestyle factors like smoking and alcohol consumption, as well as some genetic conditions, can negatively affect folate absorption.

Maximising Folate in Your Diet

How you prepare your food can significantly impact its nutrient content. Folate is both water-soluble and sensitive to heat, meaning it can be easily lost during cooking.

• Green Vegetables: To retain the most nutrients, consume them raw where possible. Otherwise, opt for quick cooking methods like steaming, stir-frying, or roasting. Boiling should be the last resort, as folate can leach into the cooking water.
• Liver: To preserve its nutrients and texture, liver is best cooked gently, as you would a quality steak—medium-rare is ideal. Pan-frying with onions is a classic preparation.
• Fruit and Produce: Always aim to eat fruit whole, fresh, and in season. For those in Brisbane and surrounding areas like Holmview, exploring local farmers’ markets is a fantastic way to find a wide variety of fresh produce, including the nutrient-dense Asian vegetables mentioned earlier.
