Omega-3 Fatty Acids Essential For Pregnancy, Nursing, and Baby

Omega-3 Fatty Acids” is a broad name for several fats that are considered good and beneficial for health. The term omega-3 is simply related to their chemical composition. The body’s most favorite omega-3 is DHA, and it is abundant in the brain and the retina of the eye. It works to promote normal mental function, memory, and visual acuteness.

DHA and Other Omega-3’s

DHA can be obtained from fatty fish such as salmon, herring, tuna, mackerel, halibut, sardines, and anchovies. ALA is one of the omega-3 fatty acids that is found in plants such as walnuts, flax seeds, and canola. Although our bodies can make DHA from ALA, this process is not very efficient, in both adults and infants, and varies among individuals. For that reason, it is recommended that DHA be part of the diet. EPA is another one of the omega-3 fatty acids found in fish sources, which, in combination with DHA, helps to ensure normal neural and cognitive function.

For the Pregnant and Nursing Mom

During the third trimester, DHA builds up at a high rate in the neurological tissue of the fetus, mainly the brain and the retina of the eye. It comes from the mom’s blood through the placenta. Studies found that women who have higher DHA in their blood when they were pregnant give birth to babies with higher DHA in their blood as well. Because of its role for fetus brain and sight development, pregnant women need a diet rich in DHA. The American Dietetic Association recommends 8 ounces of fatty fish a week.

Women need to know that the benefit of DHA extends beyond their babies. One study reported that the level of DHA in pregnant women drops significantly during the third trimester—the same time it builds up in fetus brain and retina. When they re-measured DHA six weeks after delivery, the stores were still low. The deficiency was even more notable in breast-feeding moms. This means any woman who ever had a baby in her life has less DHA in her blood. Not good news.

For the Full Term and Preterm Baby

DHA is necessary for full and preterm babies because it continues to play a role in cognitive function after birth. Research in this direction started when studies found that breast-fed babies perform better on cognitive tests than formula-fed babies—that is prior to DHA-enriched formulas. What they also observed is that compared to formula-fed babies, the blood of breast-fed babies contained more DHA. Although these findings were preliminary and the effect could not be directly attributed to DHA, they were the beginning of a plethora of research in this field.

Studies found that indeed, DHA is important for brain and vision development. Thirty percent of the human brain is made of fat; of which almost half is DHA. Less than optimal DHA in your baby’s diet can have long-term effects that could interfere with neurological development, learning behavior, habituation, exploring new environments, and learning through smell sensation. When babies were fed DHA-rich diets, either fortified formulas or breast milk, they performed better on visually based tasks. They also showed better brightness discrimination and visual potential.

Because pre-term babies missed on the opportunity to accumulate DHA in the uterus, the effect of a DHA-rich diet is more pronounced when compared to full term babies.

DHA content of breast milk is variable and depends on the nursing mom’s diet

Breast milk contains 150 different fatty acids whose proportions mirror the amount and type of fat in the diet. In other words, when the mom takes in adequate DHA, there is more of it in her breast milk and thus in her baby’s blood. This, in return, leads to better language and vocabulary comprehension, according to several studies.

Even more, the amount of DHA in breast milk varies among women of different cultures. Compared to Japanese and Chinese women, whose diets usually consist of plenty of seafood, Western women were found to have less DHA in their breast milk. Since fish is not a staple in the American diet, a little effort—and creativity—is necessary to embrace it in the dinner menu.

OMEGA-3 FATTY ACIDS supplements

Fish oil supplements are an alternative when eating 8-12 ounces of fish a week becomes challenging. For women who eat little fish, taking a daily a supplement that contains 200 mg DHA is recommended. In fact, it does not make any difference if DHA comes from algae, fish oils, or fortified foods. Up to 1 g (1,000 mg) DHA a day and 3 g (3,000 mg) DHA and EPA a day is considered safe.

  • Infant formulas with DHA and ARA

In 2002, Mead Johnson released Enfamil Lipil, the first infant formula on the market with added DHA and ARA.Today, many products followed their footsteps and released supplemented products as well. The source of DHA and ARA are algae and fungi, which are approved by the Food and Drug Administration.

ARA is a fatty acid, not an omega-3, that is also necessary for brain development. Our bodies can make ARA from other fatty acids. However, when infants were given formulas fortified with DHA alone, negative effects on language and growth started to appear. Because too much DHA can compete with ARA and lessen its availability in the body, infant formulas must provide a balance of the two fatty acids.

OMEGA-3 FATTY ACIDS in Breast feeding vs. formula feeding

The widespread use of fortified infant formulas does not change the fact that breastfeeding remains the recommended method for optimum nutrition. After all, Similac Advance is marketed as containing “DHA and ARA, special nutrients found in breast milk” and Enfamil Lipil as the “closest formula to breast milk.”

Whether you are nursing or not, make sure you are getting enough of these super fatty acids. Two meals of fatty fish a week will do it.  As for your baby, if you are taking care of your needs, your body is taking care of his. And if you are using infant formula, choose one that is fortified with ARA and DHA to build the solid nutrition foundation your baby needs to grow and learn.

Is grazing bad for gut health? Grazing and eating too frequently interferes with the MMC (motor migrating complex) and may promote bacterial overgrowth. In episode 21 of the Thank Gut It’s Fixed Show, I talk about the potential problems that can happen with grazing and eating small meals too frequently.

Is Grazing Bad for You?

Let’s talk about that!

It’s often been said that grazing may potentially help you lose weight, but today I want to talk about why grazing is actually not beneficial for your gut health. Just to give you a little bit of background, a reporter reached out to me this past week, and they were trying to come up with an article about weight loss and general health advice. They asked me what my opinion is on grazing and eating smaller meals throughout the day. I’m actually a proponent of larger, fewer meals in the day, and that’s what I will be talking about today.

When you eat several times throughout the day, your body is producing insulin constantly. Insulin is your fat storage hormone-it’s going to signal your body to dump the extra glucose in your blood into your fat issues and prevent you from losing weight. Plus, each time you eat, you have an opportunity to overeat – even by a little bit. It’s one more opportunity to make a bad choice. The more decisions you have to make related to your food, the more overwhelming it can be.

Migrating Motor Complex

Something that I don’t always get a chance to explain, and a lot of times people don’t focus on, is that grazing can contribute to and affect so many digestive issues. So let’s talk about the digestive system and is grazing bad for it? The digestive system is made up of the esophagus, the stomach, the small intestine, and the large intestine. Until you get rid of food, your body will go through a series of motions or contractions called “peristalsis”. What happens is this will help your body chew up the food in your stomach, then push it to the out of the stomach. Then the food will travel through all of the small intestines. When it reaches the large intestine, it will develop waste (poop!), and then you get rid of whatever is left from your food.

Imagine a snake trying to move–that’s exactly how the muscles contract in your digestive system. Once the food is pushed down, it’s time for clean up! A series of motions called the “Migratory Motor Complex” or “Migrating Motor Complex” (MMC) push any waste, bacteria or undigested food particles outside the small intestine into the large intestine. It takes about 3 hours from the stomach to the end of the SMALL intestine for the cleaning process to finish.

Why is this important?

The majority of bacteria lives in your gut in the LARGE intestine. That’s where good fermentation should happen. There’s a muscle that separates the small and large intestine, and it locks up so bacteria doesn’t travel backwards. But without the MMC working properly, bacteria stay and populate in the small intestine. That leads to a condition know as small intestinal bacteria overgrowth (SIBO) that I talked about on episode 16.

Whether you have SIBO or not, you may have symptoms related to disruptions in your MMC. You may have bloating, gas, indigestion. You may have heartburn or constipation because food is not moving properly through the gut. Bacterial in the small intestine-where they shouldn’t be–are eating your food and using nutrients before you have a chance to digest and absorb them. You could end up with fatigue or other issues due to nutrient deficiencies. We definitely don’t want overgrowth of bacteria in the small intestine!

MMC is a very key and integral part of your gut health. It’s what makes sure all of this bacteria gets pushed to the large intestine where it’s okay to have them there. That’s where they’re supposed to be and that’s where the fermentation happens, but not in the small intestine.

How Is Grazing Bad for my Gut?

What does all of this have to do with grazing and eating? What interrupts the migrating motor complex? Eating! It takes 3 hours to go through this process, and for some people, it may even take longer. If you have a longer transit time, because of thyroid issues for example, the MMC needs more time for you.

So is grazing bad for your gut? Yes! Every time you eat this process stops and has to reset. The sweeping motion has to start again from the top, going back to the stomach. MMC starts after your finish eating, but if you eating again an hour and a half later, it resets. Your small intestine may never actually experience a full wave of cleaning. It’s like sweeping your kitchen when your kids are around. They step on the dust and all of the dirt you just collected, and then you have to start all over again.

The same thing happens with your digestive system! MMC does not work if you eat or if you keep interrupting it with food or meals. We also know that having low hydrochloric acid in the stomach can reduce the speed of MMC. I’ve talked about acid, how it’s important, so many times before (read this post).

Furthermore, taking a PPI medication, proton pump inhibitors, Prevacid or Nexium, whether long term or even for a short period of time will reduce the acid which is protective and helps speed up digestion and MMC. Read more about the side effects of PPIs here.

Stress is also going to slow down or shut down digestion and MMC. When you are always in a chronic state of stress, your body thinks that it’s going to escape because the threat is coming. Digestion is pushed to the back burner, it’s not a priority anymore! The body will shut down the muscle movement because we need to get all of the energy and all of the blood to our skeletal muscles to run away from this foreign animal or this monster attacking us! The stress of our day to day lives doesn’t really go away, we’re carrying it on our shoulders every single day, so we have to learn how to manage it for our own sanity and for gut health!

Is Grazing Bad for Digestive Health? The Take Home Message

Things that slow MMC and proper gut cleaning include eating, low HCL, PPIs use, stress and constipation, and I also want to throw in the thyroid because it can slow down everything in your body including the muscle movement of your gut. What are the symptoms that you may experience if you have that problem? You may feel gas, bloated, indigestion, heartburn, constipation. You are more likely to have SIBO if you graze too much.

MMC is also managed by your nervous system and this may be something that’s out of your control. For example, Parkinson’s disease disrupts the nerve impulses or the nerve signaling between the brain and the gut, and there may be little that you can do to change that. But we can control how often we eat. After finishing your meal, give your gut four hours so that it can go through this cleaning motion properly.

Also, the MMC is working when you sleep. It allows your gut to go through more cleaning, getting rid of waste, and pushing bacteria to the large intestine. That’s why sleeping is important, and that’s why not eating at night is also really important.

As a fun fact, if you hear your stomach growling a few hours after a meal it is very likely that this is your MMC contracting and the muscles in your gut moving. Next time you hear this sound know that your gut is doing its job! If it hasn’t been three hours yet since your last meal, wait a little bit. Don’t rush eat. Give your body some time to promote proper gut health and prevent SIBO or other digestive issues.

I hope this was helpful! This was just a quick look into grazing and how it affects your digestive health. You can try to do it on your own and put the pieces together. However, if you want clarity and the fastest route to help heal your gut and get it to its best health, I highly recommend working with someone who is experienced in this area.

Nour’s guidance and expertise was the key to dramatically halting our son’s [Crohn’s] disease progression! His pediatric gastroenterologist is now in agreement of our choice to treat solely with diet and supplements. All his labs have improved and his inflammatory markers are so low they are practically nonexistent.

Before working with Nour, I experienced intestinal pain off and on for for 54 years with minimal success on medications. I have benefited 100% from Nour’s program as I am now pain free!

A lot of time and money was wasted on foods that I thought would help my digestive struggles [diarrhea, bloating, hunger], but in fact I was making it worse. The main benefit is getting a handle on what negatively affects my digestive symptom. Doing a total 180 to my eating habits has been pretty amazing.
