Is Vegan Breast Milk Sufficient?

June 27, 2023 by Dr. Steve Chaney

What Can Vegan Moms Do?

Author: Dr. Stephen Chaney

A whole food vegan diet is incredibly healthy:

Vegans are less likely to be overweight than the general population.

Vegans have a lower risk of diabetes, heart disease, cancer, hypertension, and several other diseases than the general population.

Whole food vegan diets are anti-inflammatory, so they lower the risk of autoimmune diseases and the “itis” diseases.

But vegan diets leave out meat, dairy, and eggs. Vegetarians without proper dietary advice are at high risk of inadequate intake of vitamin B12, vitamin D, iron, iodine, calcium, and DHA. And, of course, the risk of inadequate intake is even greater for vegans than it is for vegetarians, who may include some dairy and eggs in their diet.

So, it is legitimate to ask whether a vegetarian or vegan diet is sufficient for pregnancy and lactation. The short answer is that they can be if they are properly designed and properly supplemented.

But that is not an easy task, as evidenced by a recent study (N Ureta-Velasco et al., Nutrients 15:1855, 2023) comparing the breast milk of omnivore moms with the breast milk of vegetarian and vegan moms.

How Was This Study Done?

This study was done with 92 omnivore moms, 9 vegetarian moms (5-ovo-vegetarian and 4 lacto-ovo-vegetarians) and 11 vegan moms between August 2017 and February 2020 at the Regional Human Milk Bank at the “12 de Octubre” University Hospital in Madrid, Spain. The vegetarian and vegan moms were grouped together for data analysis.

On Day 0 of the study, participants went to the regional milk bank for blood and urine samples to determine nutritional status, a screening to determine health and socioeconomic status, and for food frequency questionnaire to characterize their habitual diet.

On days 1-5, they returned to the regional milk bank with a 24-hour diet recall of the previous day and to express 25 ml of breast milk to determine its nutrient content. On day 6, they returned to express a larger sample of breast milk to determine its lipid content (including EPA and DHA).

Note: Both the food frequency questionnaire and the 24-hour dietary recalls included nutrients derived from supplements.

What Did The Study Show About Dietary Intake of Key Nutrients?

This was a comprehensive study, so I will just cover the highlights here:

Birth Weight: Compared to the children of omnivore moms, the children of vegetarian/vegan moms were more likely to:

Have less weight gain during pregnancy (2 pounds less on average).

Be underweight at birth (60% of babies born to vegetarian/vegan moms were in the underweight category of birth weights versus 25% for babies born to omnivore moms).

This is probably because vegetarian/vegan moms:

Consumed slightly fewer calories per day (2146 versus 2319).

Consumed significantly less protein (67 g/d versus 96 g/d).

Were 10 times more likely to be underweight prior to pregnancy (10% versus 1%).

This is a concern because low birth weight increases the risk of physical and mental health issues later in life.

Supplement Use: The nutrients of greatest concern in a vegetarian/vegan diet are vitamin B12, vitamin D, iron, iodine, calcium, and DHA. For all these nutrients except DHA, this message appears to have gotten out to most vegetarian/vegan mothers because they were compensating for these potential deficiencies through supplementation.

For example, when they looked at average daily intake of these key nutrients from supplements, they found:

Nutrient	Vegetarian/Vegan Moms	Omnivore Moms
Vitamin D	1,080 IU (27mcg)	240 IU (6 mcg)
Folic acid	400 mcg	280 mcg
Vitamin B12	312 mcg	2 mcg
Calcium	566 mg	164 mg
Iron	40 mg	29 mg
DHA	100 mg	180 mg

However, that doesn’t tell the whole story, because not all vegetarian/vegan moms took supplements. When the investigators looked at the percent taking supplements, this is what they found.

Nutrient	Vegetarian/Vegan Moms	Omnivore Moms
Vitamin D	50%	50%
Folic acid	35%	61%
Vitamin B12	85%	60%
Calcium	15%	37%
Iron	25%	43%
DHA	10%	16%

Dietary Intake (Food + Supplements): The extra supplementation clearly played an important role because when the investigators looked at the overall intake from food and supplements, they found:

Nutrient	Vegetarian/Vegan Moms	Omnivore Moms
Vitamin D	224 IU (5.6 mcg)	432 IU (10.8 mcg)
Folate + Folic acid	668 mcg	473 mcg
Vitamin B12	258 mcg	6.9 mcg
Calcium	910 mg	1148 mg
Iron	31 mg	25 mg
DHA	110 mg	380 mg

Again, this doesn’t tell the whole story. Some women didn’t supplement. When the investigators looked at the percentage of women getting an inadequate intake of key nutrients from food plus supplements they found:

Nutrient	Vegetarian/Vegan Moms	Omnivore Moms
Vitamin D	75%	88%
Folate + Folic acid	0%	39%
Vitamin B12	25%	0%
Calcium	45%	40%
Iron	Not reported	Not reported
DHA	Not reported	Not reported

These results clearly show the need for supplementation. While the average intake from food plus supplements looked good, there were a significant percentage of women who weren’t getting adequate intake of key nutrients because they didn’t supplement.

The exceptions were folate + folic acid for vegetarian/vegans because their diet is rich in folate-containing foods and vitamin B12 for omnivores because their diet is rich in foods containing B12.

Is Vegan Breast Milk Sufficient?

Of course, the proof is in the pudding. When the investigators looked at the nutrient content of breast milk, this is what they found:

Nutrient	Vegetarian/Vegan Moms	Omnivore Moms	Reference Value*
Vitamin D3	1.1 mcg/L	3.4 mcg/L	0.25-2 mcg/L
Folate + Folic acid	19 mcg/L	20 mcg/l	80 mcg/L
Vitamin B12	0.74 mcg/L	0.65 mcg/L	0.5 mcg/L
Calcium	83 mg/L	99 mg/L	200-300 mg/L
Iron	Not reported	Not reported
DHA	0.15 g/100 g fat	0.33 g/100 g fat	0.35 g/100 g fat

*Reference values established by WHO

The chief difference between breast milk from vegetarian/vegan moms was in DHA levels.

That’s because the diet of vegetarians and vegans contains very little DHA, and very few vegetarian/vegan women in this study supplemented with DHA.

This study also found that breast milk from both vegetarian/vegan moms and omnivore moms was low in folate + folic acid, calcium, nicotinamide, and selenium. They said that requires follow-up in future studies.

The authors concluded, “The most important contribution of this study is the detailed and comprehensive description of micronutrients and lipids in human milk from omnivore milk donors and vegetarian/vegan women…Of particular concern is the lower DHA content in the milk of our vegetarian/vegan group. However, raising awareness and administering proper supplementation could bridge the gap, as has been the case with vitamin B12.”

What Can Vegan Moms Do?

This study emphasizes the importance of careful planning and supplementation during pregnancy and lactation if you are a vegetarian or vegan mom.

For example, the vegetarian/vegan women in this study were more likely to have low birthweight babies, and low birthweight infants are at risk for health issues later in life. That means:

Careful planning is required to select calorie- and protein-rich plant foods.

A high-quality plant protein supplement can be a great help.

Supplementation is particularly important during lactation to assure your breast milk adequately nourishes your newborn baby. For example, in this study:

The vitamin B12 level in the breast milk from vegetarian/vegan moms was adequate because 85% of them supplemented with vitamin B12.

The DHA level in the breast milk from vegetarian/vegan moms was inadequate because only 10% of them supplemented with DHA.

The authors of this study recommended that vegetarian and vegan moms consume at least 200 mg of DHA from algal sources while they are breastfeeding.

However, finding a prenatal supplement that provides all the nutrients you need prior to pregnancy, during pregnancy, and while breastfeeding is challenging. I gave you 7 tips for choosing the best prenatal supplements in a previous “Health Tips From the Professor” article.

The Bottom Line

A recent study asked whether the breast milk of vegetarian and vegan moms was sufficient for the needs of their newborn babies. The study found that:

Folate levels in their breast milk were sufficient because the diets of vegetarians and vegans contain many folate-rich foods.

Vitamin B12 levels in their breast milk were sufficient because 85% of the vegetarian and vegan women in this study supplemented with vitamin B12.

DHA levels in their breast milk were insufficient because the diets of vegetarian and vegan women are very low in DHA, and only 10% of the women in this study supplemented with DHA.

The authors of this study recommended that vegetarian and vegan moms consume at least 200 mg of DHA from algal sources while they are breastfeeding.

This study reinforces the need for supplementation during lactation to assure your breast milk adequately nourishes your newborn baby.

However, finding a prenatal supplement that provides all the nutrients you need prior to pregnancy, during pregnancy, and while breastfeeding is challenging. I gave you 7 tips for choosing the best prenatal supplement in a previous “Health Tips From the Professor” article.

My posts and “Health Tips From the Professor” articles carefully avoid claims about any brand of supplement or manufacturer of supplements. However, I am often asked by representatives of supplement companies if they can share them with their customers.

My answer is, “Yes, as long as you share only the article without any additions or alterations. In particular, you should avoid adding any mention of your company or your company’s products. If you were to do that, you could be making what the FTC and FDA consider a “misleading health claim” that could result in legal action against you and the company you represent.

Prenatal Supplements Strike Out Again

May 9, 2023 by Dr. Steve Chaney

Is It Three Strikes And You Are Out?

Author: Dr. Stephen Chaney

If you are pregnant, you want the best for your unborn baby. Your doctor has recommended a prenatal supplement, but do the prenatal supplements on the market meet your needs? A few months ago, I shared two studies that concluded that most prenatal supplements on the market are woefully inadequate.

In fact, the authors said, “[Our] analysis found that prenatal supplements vary widely in content, often only contain a subset of essential vitamins, and the levels were often below…recommendations.”

In other words, their study found that most prenatal vitamins on the market may not be adequate to support your needs and the needs of your child through pregnancy and breastfeeding.

Now, a third study on the topic has been published (KA Saunders et al, American Journal of Clinical Nutrition, 117: 823-829, 2023. It differs from the previous studies in that:

1) The previous two studies took a comprehensive approach, while this study focused on 6 key nutrients.

The previous studies included all nutrients important for a healthy pregnancy including choline, iodine, and vitamin K, which have only recently been shown to be important for a healthy pregnancy.

This study focused on 6 nutrients, vitamin A, vitamin D, folic acid, calcium, iron, and omega-3 fatty acids, which have long been recognized as essential for a healthy pregnancy.

2) The previous two studies focused on prenatal supplements, while this study focused on all supplements that might be taken by pregnant women.

3) The previous two studies asked whether supplements provided recommended amounts of all nutrients needed for a healthy pregnancy. This study took a “Goldilocks approach” and asked whether levels of these 6 essential nutrients were appropriate (“just right”). The study:

Started by determining the intake of these 6 key nutrients by American women. The authors of the study then added the amount of each nutrient provided by the supplements in their study to the amount of that nutrient in the diet of American women and:

- Calculated the minimum amount of each nutrient that would be needed to assure that 90% of American women taking a particular supplement would meet the recommended intake for pregnant and lactating women.

- Calculated the maximum amount of each nutrient provided by supplements in their study to assure that that 90% of American women taking that supplement would not get potentially toxic amounts of that nutrient.

In other words, for each of the 6 nutrients they calculated a supplemental dose range that was neither too low nor too high. They called this the “appropriate dose range” for each nutrient. Goldilocks would have called it “just right”.

I’m sure you are anxiously waiting to learn what their study found. But before we go there, I will describe how the study was done.

How Was The Study Done?

For the dietary intake portion of the study, the authors used dietary intake data previously collected from the Environmental Influences on Child Health Outcomes (ECHO) study.

The ECHO study is a consortium of 69 medical centers across multiple states. It is an observational study of mothers and their offspring designed to understand the effects of early life exposures on child health and development.

The current study analyzed dietary intake data for 2450 participants from 6 medical centers across 5 states in the ECHO study. The women in this study were diverse with respect to ethnicity, education, and weight.

All pregnant women in the current study completed at least one 24-hour dietary recall between 6-week gestation until delivery (24% completed one dietary recall. 76% completed two or more dietary recalls). Dietary intake was generally assessed with an expert interviewer and included all foods and beverages consumed in the previous 24 hours.

For the supplement portion of the study, the authors used the NIH Dietary Supplement Label Database because it is the most complete listing of supplements in the US. The authors selected 20,547 supplements that contained at least one of the 6 essential nutrients from this database.

To determine which of the 20,547 supplements contained appropriate levels of the 6 nutrients (vitamin A, vitamin D, folic acid, calcium, iron, and omega-3 fatty acids) selected for this study, the authors used the process described in the introduction above. Briefly:

The authors added the amount of each nutrient provided by the supplements in their study to the amount of that nutrient in the diet of American women and:

Calculated the minimum amount of each nutrient that would be needed to assure that 90% of American women taking a particular supplement would meet the recommended intake for pregnant and lactating women.

Calculated the maximum amount of each nutrient provided by supplements in their study to assure that that 90% of American women taking that supplement would not get potentially toxic amounts of that nutrient.

In other words, for each of the 6 nutrients they calculated a supplemental dose range that was neither too low nor too high. They called this the “appropriate dose range” for each nutrient.

Why Are The 6 Nutrients Included In This Study Important?

Dietary Intake Is Often Inadequate

The diet analysis of pregnant American women in this study found:

42% were at risk of inadequate vitamin A intake.

96% were at risk of inadequate vitamin D intake.

45% were at risk of inadequate folic acid intake.

55% were at risk of inadequate calcium intake.

93% were at risk of inadequate iron intake.

67% were at risk of inadequate omega-3 intake.

The percentage of women at risk for inadequate intake of these nutrients varied with age, ethnicity, and income levels. But the overall message is clear. Most American women are not getting enough of these essential nutrients from their diet alone.

The Risk of Inadequate and Excessive Intake Of These Nutrients

These 6 nutrients were chosen in part because reviews by the Cochrane Collaboration have concluded that inadequate intake of these nutrients are associated with complications during pregnancy and delivery. They can also adversely affect the health and normal development of the baby.

This is important because the Cochrane Collaboration is considered the Gold Standard of clinical studies. You can find a more detailed description of Cochrane Collaboration studies and why they are the Gold standard here.

[Note: The Cochrane Collaboration has not yet evaluated choline, iodine, and vitamin K for pregnant women, but their inclusion in prenatal supplements is supported by multiple clinical studies.]

In addition, excess intake of all these nutrients except omega-3s can harm both the fetus and the mother. The is why the Food and Nutrition Board has set ULs (Upper Limits – the level above which toxicity can occur) for 5 of the 6 nutrients. This is important because previous studies have suggested that up to 25% of women may be getting toxic levels of one or more of these nutrients when you consider both their dietary intake and their prenatal supplement.

Summary

In other words, both too little and too much of these nutrients can harm the mom and her baby. It is critical that prenatal supplements get the dosing right.

It is for that reason that the authors of this study have set an “appropriate dose range” (high enough that 90% of women have enough of each nutrient to prevent deficiency and low enough that 90% of women do not exceed the UL for each nutrient) as the standard for evaluating the adequacy and safety of supplements for pregnant women.

Prenatal Supplements Strike Out Again

Of the 20,547 supplements (421 labeled as prenatal supplements) available on the US market as of December 31, 2022, the investigators reported that:

Only 69 (0.3%) supplements contained all 6 nutrients considered essential for a healthy pregnancy.

Only 1 supplement contained all 6 nutrients at the appropriate doses, and it wasn’t even labeled as a prenatal supplement.

In addition:

One supplement containing all 6 nutrients put 100% of the women in their study at risk for excessive intake of folic acid.

Another supplement containing all 6 nutrients put 46% of the women in their study at risk of inadequate calcium intake.

The authors concluded, “Almost no US dietary supplements provide key nutrients in the doses needed for pregnant women. Affordable and convenient products that fill the gap between food-based intake and estimated requirements of pregnancy without inducing excess intake are needed to support pregnant women and their offspring.”

In short, the conclusion of this study can be summed up as, “Prenatal Supplements Strike Out Again”.

[Note: It sometime takes a while for supplement labels to be posted in the NIH Dietary Supplement Label Database. The authors acknowledged that this study may not include supplements introduced or reformulated in the last quarter of 2022.]

Is It Three Strikes And You Are Out?

If you are pregnant or thinking of becoming pregnant, this should be a wake-up call.

70% of pregnant women in this country take prenatal supplements, usually based on recommendations by their health care provider. They assume the prenatal supplements meet their needs and the needs of their unborn baby.

Yet three studies evaluating the adequacy of prenatal supplements have been published in the past few months. They took very different approaches in evaluating the supplements. But all three studies concluded that the vast majority of prenatal supplements on the market are woefully inadequate.

You may be wondering, “Is it three strikes, and you are out?” Are there no decent prenatal supplements on the market? The answer to those questions is, “No. There are good prenatal supplements on the market.”

You may be wondering how I can say that in the face of such overwhelming negative data. That’s because while all 3 studies were very good studies, they each had “blind spots”:

1) Each of the studies used very stringent criteria for identifying adequate prenatal supplements. In some cases, their criteria were stricter than the RDA recommendations and the recommendations of the American College of Obstetrics and Gynecology for pregnant and lactating women. It could be argued that their criteria were too stringent.

2) In the case of the current study, it could also be argued that evaluating only 6 nutrients is not a good criterion for evaluating the adequacy of prenatal supplements. For example, I looked up the one supplement rated as adequate in this study. It does provide appropriate doses of the 6 nutrients this study focused on. It also provides appropriate doses of vitamin K and iodine. But it does not provide choline. It is a very good supplement for women, but it is not the perfect prenatal supplement.

So, what can you do? How can you find the best prenatal supplement for you? Unfortunately, you cannot rely on advice from your friends or your health professional. You cannot rely on advertisements. That is a good place to start, but you have to do your own sleuthing.

With that in mind, I have listed 7 simple rules for selecting the best possible prenatal supplement in my article about the first two studies. Use these rules for evaluating every prenatal supplement you come across. Happy sleuthing.

The Bottom Line

A recent study evaluated all 20,547 supplements on the US market to see if they met the needs of pregnant women in this country.

They focused on 6 nutrients (vitamin A, vitamin D, folic acid, calcium, iron, and omega-3s) known to be essential for a healthy pregnancy.

They determined the dietary intake for all 6 nutrients in a cross section of pregnant women in the US.

They added the amount of the 6 nutrients in each of the 20,547 supplements to the dietary intake of those nutrients by pregnant women.

They then asked which supplements provided the “appropriate dose” of all 6 nutrients. They defined “appropriate dose” as the dose range that was.

- High enough to prevent deficiency of that nutrient in 90% of pregnant women taking the supplement…and…

- Low enough to prevent toxicity from that nutrient in 90% of pregnant women taking the supplement.

In other words, for each of the 6 nutrients they calculated a supplemental dose range that was neither too low nor too high.

Of the 20,547 supplements (421 labeled as prenatal supplements) available on the US market:

Only 69 (0.3%) supplements contained all 6 nutrients they considered essential for a healthy pregnancy.

Only 1 supplement contained all 6 nutrients at the appropriate doses, and it wasn’t even labeled as a prenatal supplement.

500th Issue Celebration

November 15, 2022 by Dr. Steve Chaney

Nutrition Breakthroughs Over The Last Two Years

Author: Dr. Stephen Chaney

In the nearly ten years that I have been publishing “Health Tips From The Professor”, I have tried to go behind the headlines to provide you with accurate, unbiased health information that you can trust and apply to your everyday life.

The 500^th issue of any publication is a major cause for celebration and reflection – and “Health Tips From The Professor” is no different.

I am dedicating this issue to reviewing some of the major stories I have covered in the past 100 issues. There are lots of topics I could have covered, but I have chosen to focus on three types of articles:

Articles that have debunked long-standing myths about nutrition and health.

Articles that have corrected some of the misinformation that seems to show up on the internet on an almost daily basis.

Articles about the issues that most directly affect your health.

Best Ways To Lose Weight

Since it is almost January, let’s start with a couple of articles about diet and weight loss (or weight gain). I have covered the effectiveness of the Paleo, Keto, Mediterranean, DASH, vegetarian, and Vegan diets for both short and long-term weight loss in my book “Slaying The Food Myths”, so I won’t repeat that information here. Instead, I will share a few updates from the past 100 issues.

My Tips On The Best Approach For Losing Weight: Every health guru has a favorite diet they like to promote. I am different. My book, Slaying the Food Myths, is probably the first “anti-diet” diet book ever written. Based on my years of research I can tell you that we are all different. There is no single diet that is best for everyone. In this article I have summarized my tips for selecting the weight loss diet that is best for you.

The US News & World Report’s Recommendation For the Best Diets: Each year US News & World Report assembles some of the top nutrition experts in the country and asks them to review popular diets and rank them for effectiveness and safety. In this article I summarize their ratings for 2022.

Does Intermittent Fasting Have A Downside? In previous articles in “Health Tips From the Professor” I have reported on studies showing that intermittent fasting is no more effective for weight loss than any other diet that restricts calories to the same extent. But does intermittent fasting have a downside? In this article I reported on a study that suggests it does.

Can A Healthy Diet Help You Lose Weight? Most investigators simply compare their favorite diet to the standard American diet. And any diet looks good compared to the standard American diet. In this article I reported on a study that compared two whole food diets that restricted calories by 25% to the standard American diet. One calorie-restricted diet was more plant-based and the other more meat-based. You may be surprised at the results.

Omega-3s

Omega-3s continue to be an active area of research. Here are just a few of the top studies over the past two years.

Do Omega-3s Oil Your Joints? In this article I reviewed the latest information on omega-3s and arthritis.

Do Omega-3s Add Years To Your Life? In this article I discussed a study that looks at the effect of omega-3s on longevity.

The Omega-3 Pendulum: In this article I discuss why omega-3 studies are so confusing. One day the headlines say they are miracle cures. A few weeks later the headlines say they are worthless. I discuss the flaws in many omega-3 studies and how to identify the high-quality omega-3 studies you can believe.

Do Omega-3s Reduce Congestive Heart Failure? In this article I review a recent study on omega-3s and congestive heart failure and discuss who is most likely to benefit from omega-3 supplementation.

Plant-Based Diets

Will Plant-Based Proteins Help You Live Longer? In this article I review a study that looks at the effect of swapping plant proteins for animal proteins on longevity.

Can Diet Add Years To Your Life? In this article I review a study that takes a broader view and asks which foods add years to your life.

Is A Vegan Diet The Secret To Weight Loss? This is an update of my previous articles on vegan diets. This article asked whether simply changing from a typical American diet to a vegan diet could influence weight loss and health parameters in as little as 16 weeks. The answer may surprise you.

Is A Vegan Diet Bad For Your Bones? No diet is perfect. This article looks at one of the possible downsides to a vegan diet. I also discuss how you can follow a vegan diet AND have strong bones. It’s not that difficult.

Anti-Inflammatory Diets

What Is An Anti-Inflammatory Diet? In this article I discuss the science behind anti-inflammatory diets and what an anti-inflammatory diet looks like.

Can Diet Cause You To Lose Your Mind? In this article I discuss a study looking at the effect of an inflammatory diet on dementia. The study also looks at which foods protect your mind and which ones attack your mind.

Do Whole Grains Reduce Inflammation? You have been told that grains cause inflammation. Refined grains might, but this study shows that whole grains reduce inflammation.

Nutrition And Pregnancy

Here are the latest advances in nutrition for a healthy pregnancy.

The Perils Of Iodine Deficiency For Women. In this article I reviewed the latest data showing that iodine is essential for a healthy pregnancy and discuss where you can get the iodine you need.

Do Omega-3s Reduce The Risk Of Pre-Term Births? You seldom hear experts saying that the data are so definitive that no further studies are needed. In this article I reviewed a study that said just that about omega-3s and pre-term births.

Does Maternal Vitamin D Affect ADHD? In this article I reviewed the evidence that adequate vitamin D status during pregnancy may reduce the risk of ADHD in the offspring.

How Much DHA Should You Take During Pregnancy? In this article I reviewed current guidelines for DHA intake during pregnancy and a recent study suggesting even higher levels might be optimal.

Is Your Prenatal Supplement Adequate? In this article I reviewed two studies that found most prenatal supplements on the market are not adequate for pregnant women or their unborn babies.

Children’s Nutrition

Here are the latest insights into children’s nutrition.

Are We Killing Our Children With Kindness? In this article I reviewed a recent study documenting the increase in ultra-processed food consumption by American children and the effect it is having on their health. I then ask, is it really kindness when we let our children eat all the sugar and ultra-processed food they want?

Is Diabetes Increasing In Our Children? In this article I reviewed a study documenting the dramatic increase in diabetes among American children and its relationship to ultra-processed food consumption and lack of exercise.

How Much Omega-3s Do Children Need? In this article I reviewed an study that attempts to define how much omega-3s are optimal for cognition (ability to learn) in our children.

Diabetes

Here are some insights into nutrition and diabetes that may cause you to rethink your diet.

Does An Apple A Day Keep Diabetes Away? You may have been told to avoid fruits if you are diabetic. In this article I reviewed a study showing that fruit consumption actually decreases your risk of diabetes. Of course, we are all different. If you have diabetes you need to figure out which fruits are your friends and which are your foes.

Do Whole Grains Keep Diabetes Away? You may have also been told to avoid grains if you are diabetic. In this article I reviewed a study showing that whole grain consumption actually decreases your risk of diabetes. Once again, we are all different. If you have diabetes you need to figure out which grains are your friends and which are your foes.

Heart Disease

Here is an interesting insight into nutrition and heart disease that may cause you to rethink your diet.

Is Dairy Bad For Your Heart? You have been told that dairy is bad for your heart AND that it is good for your heart. Which is correct? In this article I discuss some recent studies on the topic and conclude the answer is, “It depends”. It depends on your overall diet, your weight, your lifestyle, and your overall health.

Breast Cancer

Here are some facts about breast cancer every woman should know.

The Best Way To Reduce Your Risk Of Breast Cancer In this article I review two major studies and the American Cancer Guidelines to give you 6 tips for reducing your risk of breast cancer.

The Truth About Soy And Breast Cancer You have been told that soy causes breast cancer, and you should avoid it. In this article I review the science and tell you the truth about soy and breast cancer.

Supplementation

Some “experts” claim everyone should take almost every supplement on the market. Others claim supplementation is worthless. What is the truth about supplementation?

What Do The 2020-2025 Dietary Guidelines Say About Supplements? Every 5 years the USDA updates their Dietary Guidelines for foods and supplements. In this article I discuss what the 2020-2025 Dietary Guidelines say about supplements. Yes, the USDA does recommend supplements for some people.

Who Benefits Most From Supplementation? Not everyone benefits equally from supplementation. In this article I discuss who benefits the most from supplementation.

Should Cancer Patients Take Supplements? Doctors routinely tell their cancer patients not to take supplements. Is that the best advice? In this article I review a study that answers that question.

Can You Trust Supplements Marketed on Amazon? Amazon’s business model is to sell products at the lowest possible price. But do they check the quality of the products marketed on their site? In this article I review a study that answers that question.

Is Your Prenatal Supplement Adequate? In this article I reviewed two studies that found most prenatal supplements on the market are not adequate for pregnant women or their unborn babies.

The Bottom Line

I have just touched on a few of my most popular articles above. You may want to scroll through these articles to find ones of interest to you that you might have missed over the last two years. If you don’t see topics that you are looking for, just go to https://chaneyhealth.com/healthtips/ and type the appropriate term in the search box.

In the coming years, you can look for more articles debunking myths, exposing lies and providing balance to the debate about the health topics that affect you directly. As always, I pledge to provide you with scientifically accurate, balanced information that you can trust. I will continue to do my best to present this information in a clear and concise manner so that you can understand it and apply it to your life.
