Introduction:  

Folic acid, also known as folate or Vitamin B9, plays a critical role in various bodily functions, including cell growth and the formation of red blood cells. While it’s essential to consume an adequate amount of folic acid daily, some individuals may need to adopt a diet low in folic acid due to specific health conditions or genetic factors. This article will provide you with an understanding of folic acid and its role in our bodies, the causes, and symptoms of folate deficiency, and practical tips for choosing and preparing foods that are low in folic acid. 

Understanding Folate and Folic Acid 

Overview of Folate (Vitamin B9):  

Folate is a naturally occurring form of vitamin B9. It’s found in foods like leafy greens, legumes, and fruits. Folic acid, on the other hand, is the synthetic form of folate. It’s used in supplements and fortified foods. Both folate and folic acid are vital for our health. They help convert food into energy, form red blood cells, and support healthy cell growth. 

Differences between Folate and Folic Acid 

Folate and folic acid both help keep our body functions in balance. Even though their jobs are similar, they differ in how we get them and how our bodies use them. Folate is naturally present in many foods. Folic acid is a man-made version added to supplements and fortified foods. Research shows that our bodies can use folic acid more easily than natural folate. 

Functions and Health Benefits 

Folate plays a crucial part in several key functions such as: 

• Making red blood cells. 
• Turning food into fuel for our bodies. 
• Building DNA and RNA, which are vital for cell growth and multiplication. 
• Avoiding a specific type of anemia. This type, called megaloblastic anemia, causes larger-than-normal red blood cells. 
   

During pregnancy, getting enough folate is very important. It reduces the risk of certain birth defects in babies. 

Recommended Intakes 

Adults should aim for 400 micrograms (mcg) of folate per day. Pregnant women should have a higher amount, about 600 mcg daily. Breastfeeding women should aim for 500 mcg per day. 

Folate Deficiency: Causes and Symptoms 

Causes of Folate Deficiency 

Several factors can lead to folate deficiency. These are mentioned below.  

• Diet 

A diet low in folate-rich foods, like dark leafy greens, legumes, and citrus fruits, can result in deficiency.  

• Disease 

Some health issues, like celiac disease and Crohn’s disease, impact how your body absorbs nutrients from food. This can lead to folate deficiency. 

• Genetics 

Some genetic mutations affect how the body uses folate or folic acid, they may cause a deficiency or excess of folic acid in the body.  

• Medication Side Effects 

Certain drugs can affect how our bodies use folate. For instance, phenytoin (an anticonvulsant) or methotrexate (used for managing cancer and autoimmune diseases) can interfere with the body’s ability to process and absorb folate. If you think a drug you’re taking might be causing a deficiency, discuss it with your healthcare provider. 

• Excessive Alcohol Intake 

Drinking too much alcohol harms folate absorption. It also leads to more folate being lost in urine, resulting in a deficiency.  

Symptoms of Folate Deficiency 

Folate deficiency signs can build up slowly and might not be clear at first. Below are some common signs that are discussed.  

• Anaemia 

Folate deficiency can cause a specific type of anaemia called megaloblastic anaemia, which results in red blood cells that are larger than normal and don’t work as they should. 

• Fatigue and Weakness 

Tiredness, weakness, and shortness of breath can all result from anaemia caused by folate deficiency. 

• Neurological Effects 

A lack of folate may cause tingling and numbness in your hands and feet. It might also lead to memory problems, issues focusing, and even contribute to depression, anger, and confusion. 

• Pregnancy Complications 

If pregnant women don’t get enough folate, it can lead to birth defects like spina bifida or anencephaly in the developing baby. 

Foods Low in Folic Acid 

People who need a diet low in folic acid should know which foods to pick. Let’s take a look at some food groups that have less of this nutrient. 

1. Vegetables and Fruits 

Many fruits and vegetables are high in folate. However, some options are not. 

• Specific Vegetables for a Low Folate Diet 

Choose non-green vegetables. They tend to have lesser amounts of folate which are as follows. 

• Corn 
• Potatoes 
• Cucumber 
• Bell peppers 

• Specific Fruits for a Low Folate Diet 

Some fruits are lower in folate which is as follows. 

• Apples 
• Blueberries 
• Grapes 
• Strawberries 
   

How to Choose Low-Folate Vegetables and Fruits? 

Pick fruits and vegetables that are low in folate. Try to avoid or eat less of the ones high in folate like oranges, melons, and leafy green vegetables. 

2. Grains 

If you’re after grains low in folic acid, select unfortified grains as follows. 

• Whole wheat products 
• Brown rice 
• Oats 
• Quinoa 
   

• Low Folate Bread Options 

Go for bread made from unfortified flour. This could be whole wheat or rye bread. Avoid white bread made from enriched flour as it has added folic acid. 

3. Proteins 

Select meat and fish with less folate to reduce your intake. 

• Meats Low in Folate 

There are various meats with lower folate content, like: 

• Chicken 
• Turkey 
• Pork
