Why Do You Need Supplements If You Are Eating A Healthy Diet?

By fully committing to a raw, plant-based diet, you bathe your body with extraordinary nutrients that continuously feed your cells with vitamins, minerals, antioxidants and phytochemicals that support optimum health. If that’s the case, then why do you need supplements? Shouldn’t your healthy diet be sufficient?

Supplements are indispensable to your holistic approach for vibrant health. Our resident research director, Dr. Michael Donaldson, sheds light on the four key reasons behind why our bodies require supplements to round out our healthy eating.

1) Our fruits and vegetables are not as nutritious as they once were.

Modern farming practices, such as the heavy use of fertilizers, pesticides and other substances, has resulted in soil that is almost sterile and devoid of trace minerals. As a result, our food is not as nutritious as it was decades ago. In a recent review on modern foods4, scientists found that the larger the yield of crop, the lower the mineral concentration. Furthermore, a historical analysis of the nutritional composition of fruits and vegetables has confirmed a decline in several nutrients over the last 50-70 years and, specifically, hybrid versions of broccoli, wheat and corn have also shown lower mineral content.

Because modern foods are not as nutrient-dense, there is a burgeoning demand for organic foods and heirloom varieties of produce. There is also a demand for superfoods. BarleyMax and our new Advanced Superfood blends help people get in the organic food-based nutrients that are lacking at the grocery store.

2) As you age, your body changes the way it processes food and needs more nutritional support.

In our older years, we need almost as many nutrients as we did in our youth, but we don’t burn as many calories. To compensate for this, we need to maximize the nutrients we consume in each calorie. We also need to make sure our bodies are fully fed at the cellular level. This is also where superfoods and “concentrated” foods like fresh vegetable juice really help, as you get an abundance of vegetables in a form the body can readily absorb.

One way to make the calories count is to use digestive enzymes. In-vitro work has proven that supplemental enzymes improve the digestion and absorption of nutrients from foods.5 With digestive enzymes, you can increase the delivery of calories as well as nutrients.

3) Supplements help us ease or counteract specific health conditions we encounter throughout our lifetimes.

We each have unique weaknesses, conditions or stages in life that put additional strains on us. Sometimes, there are supplements to help us get through these times until we heal and recover.

For example, if you’re undergoing cancer treatments, antioxidant supplements and concentrated dark leafy greens can lessen the side effects of these treatments without making them less effective. Probiotics are essential during and after taking antibiotics. Women experiencing peri-menopausal and menopausal symptoms can use supplements to help alleviate hot flashes, migraines, insomnia, night sweats and irregular periods.

Although the quantity and type of nutrients consumed varies from person to person, no one can rely on a healthy diet alone to effectively stave off diseases, detoxify and live as energetically and vibrantly as possible. With both a delicious, healthful diet and high-quality supplements to fill in the gaps, we can ensure we are making every effort to counteract our increased need for high-quality nutrients.

4) Certain nutrients aren’t available in optimal amounts through diet alone—regardless of the type of diet.

Vitamin B-12. Research studies have shown that many of us, whether we eat plant or animal foods, are low in vitamin B-12, especially as we age. A study of about 3,000 people found that 39% of the group was low in B-12 despite following an omnivorous diet.1 Vitamin B-12 is essential for nerve health, including brain function, for homocysteine metabolism and for energy production.
Iodine. Iodine supports the health of many organs in the body. It’s taken up by almost every gland and, when taken in milligram quantities, is found in nearly every tissue of the body. Iodine is necessary for optimal function of the breasts, ovaries, endometrium, prostate and thyroid. Your body thrives on milligram quantities of iodine not available from food. A drop or two of nascent iodine each day is an excellent way to safely optimize your iodine intake.
Vitamin D3. A lot of research has shown that almost every person in the U.S. has lower-than-optimal levels of vitamin D, which we naturally get from sunshine. In Hallelujah Diet’s bone health study, we found that both middle-aged and elderly women especially need to supplement vitamin D3 to reach optimal levels. As we age, our skin does not produce vitamin D as efficiently. A 70-year old only makes ¼ as much vitamin D as a 20-year old from the same sun exposure.2 If everyone in the U.S. took just 2,000 IU of vitamin D3 every day, the rates of heart disease, strokes, colon, breast and prostate cancer would plummet.3 

Fish Oil. The benefits of EPA and DHA found in fish oil are well known and thoroughly researched, including greater mental acuity for all ages from the youngest yet-unborn infant to the oldest adult (which includes IQ, cognitive function, depression, ADHD, autism, etc…), reduction of inappropriate chronic inflammation and improving your cardiovascular and immune systems. People following a plant-based diet need a source of preformed DHA to experience optimal health.

    Thank you for your great work to God ‘s glory!

    I am requesting information concerning your health minister training.

    Thank you and all God’s blessings, kathleen

    Is it better to take fish oil or a vegetarian source of DHA such as Udo’s oil?

  3. Tony Papandrea October 13, 2014

    Dr. Donaldson mentioned getting EPA from fish oil. Udo’s oil also has EPA in it from plant based sources. Is there a difference between the two sources of EPA? The HA diet is plant based so why would we need to use fish oil if we can get the EPA(and DHA) from sources like Udo’s? A previous poster asked a similar question regarding DHA, but a definitive answer was not really given.

    • Christy Okon October 20, 2014

      Thank you! EPA is not the concern or motivating factor for using fish oil. DHA is vital for our cells, especially for our brain and retina. The body can convert some of the short chain plant based omega 3s to DHA but not efficiently and some folks may not be able to convert any. Udo’s oil with DHA has 100 mg of DHA (derived from algae) added so each Tablespoon of Udo’s supplies 100 mg of DHA. In comparison, one teaspoon of Pharmax Finest Pure Fish oil, provides 750 mg of DHA. Knowing the critical importance of DHA and the limited ability of the body to convert land based omega 3s to DHA, we believe it prudent to insure one has an ample supply by way of supplementation. Algae derived DHA supplements are available but that is a very expensive way to get a significant amount of DHA.

  4. Seed oils are a danger to viable health. Why then do you have your supplements contain sunflower oil?

    • Melody Hord December 1, 2021

      Hi Janice,
      Yes, Many of the highly refined oils are bad for one’s health.
      However, Hallelujah Diet is a big proponent of some seed oils that are carefully extracted. Hallelujah Diet sells flax oil and Udo’s oil.
      Is there a particular product that you are referencing? Thanks.
