Pregnancy Pathway, Pregnancy — Nutrition

Fresh fruit = vitamins & minerals!!

Fresh fruit = vit­a­mins & minerals!!

Ques­tion:

How many extra calo­ries do you need in each trimester to off­set the meta­bolic cost of pregnancy?

Answer:

First trimester — 0; Sec­ond trimester — 300; Third trimester — 500 (source: Insti­tute of Medicine).

Keep in mind that you may also need calo­ries for any fit­ness pro­gram you are doing. If you are con­tin­u­ing a pro­gram, the only change is due to the pregnancy.

If you begin or increase your activ­ity, you need to take that into account. One yoga class = 100 — 150 calo­ries. One aer­o­bics class = 200–400 calo­ries. Walk one mile = 100 calories.

1 slice whole grain bread = 50-100 calories

1 slice whole grain bread = 50–100 calories

Be sure you read food labels so that you can bal­ance your food intake and your calo­rie out­put. A small woman (under 5’3″ & 130 lbs.) prob­a­bly needs about 1200 calo­ries per day as a base. A medium sized woman needs about 1400, and a large woman (over 5’9″ & 160 lbs.) prob­a­bly needs 1600 to 1800 calo­ries. Add your activ­ity and preg­nancy needs to your base amount.

Ques­tion:

What foods are nec­es­sary for a healthy pregnancy?

Answer, part A:

PROTEIN. Lean pro­teins like turkey and those with omega 3 fats like ocean fish and eggs.…yes! EGGS!

Turkey is a good protein

Turkey is a good protein

Ocean fish 1 or 2 times/wk = good protein & omega 3 fat

Ocean fish 1 or 2 times/wk = good pro­tein & omega 3 fat

Eggs are a perfect pregnancy food!

Eggs are a per­fect preg­nancy food!

70–90 grams of pro­tein are nec­es­sary each day, along with  ade­quate water.  These are needed to make an extra 40% blood vol­ume required to sup­port the placenta.

Answer, part B:

WATER. Two (2) quarts of water…more if you are very active…are needed to make extra blood and to pre­vent dehydration.

Ques­tion: What else?

Fresh vegetables also provide fiber

Fresh veg­eta­bles also pro­vide fiber

Answer: CARBS. Fresh, col­or­ful fruits & veg­gies pro­vide nec­es­sary vit­a­mins and min­er­als, as well as fiber. Eat 5 serv­ings a day from all the col­ors:  yel­low, orange, red, pur­ple and green, and you will get live vit­a­mins all day long that help your baby develop prop­erly! Fruits, veg­eta­bles and whole grains are low glycemic index car­bo­hy­drates — the good ones!

Dairy provides calcium

Dairy pro­vides calcium

Ques­tion:

Do I need dairy prod­ucts and red meat? Can I get the needed min­er­als in other ways?

Answer:

Cal­cium is needed in ade­quate amounts for bones and teeth. It is most eas­ily obtained by drink­ing milk or eat­ing cheese, yogurt or cot­tage cheese. Soy, dark green leafy veg­eta­bles and cal­cium for­ti­fied juice are alternatives.

Iron is nec­es­sary for red blood cells to take up oxy­gen. It is found in high amounts in beef,  and lesser amounts in raisins, spinach, and prune juice. Pre­na­tal vit­a­mins are your insur­ance against defi­cien­cies of these essen­tial minerals.

Ques­tion:

Any­thing else that’s essential?

Answer:

Yes! Healthy FAT!!

Avocado is an excellent source of omega 6 fat

Avo­cado is an excel­lent source of omega 6 fat

In addi­tion to omega 3 fats found in fish, wal­nuts and flax seeds, you need also need omega 6 fats, which are found in avo­ca­dos, olive oil and other veg­etable oils. Healthy fats help bal­ance car­dio­vas­cu­lar con­stric­tion and dila­tion, reduc­ing the risk for hypertension.

Last Ques­tion:

What is a healthy weight gain?

Answer:

In 2009, the National Acad­emy of Sci­ences revised its rec­om­men­da­tions. It now bases desir­able weight gain on pre-pregnancy BMI (Body Mass Index…google this!).

BMI less than 18.5 (low) — 28 to 40 lbs.; BMI between 18.5–24.9 (nor­mal) — 25 to 35 lbs.; BMI 25.0 to 29.9 (high) — 15 to 25 lbs.; obese women (BMI over 30.0) — 11 to 20 lbs.

Pregnancy Pathway — Exercise

How lucky is this? Just a few days ago, yet another study was released and has been cir­cu­lat­ing on Med­scape and other med­ical sites that indi­cates exer­cise is ben­e­fi­cial in preg­nancy, whether the mother is a pre­vi­ous exer­ciser or not. Just in time for this entry!

Behavior Affects Pregnancy Outcome

Behav­ior Affects Preg­nancy Outcome

Phys­i­cal exer­tion (we call it “exer­cise” nowa­days) is a nor­mal state for healthy humans. Only in the last cen­tury has the desire to rest or the need to store extra calo­ries as fat become more pos­si­ble to achieve than our need to move about to survive.

Preg­nancy is a state in which both of these fac­tors (rest­ing and stor­ing calo­ries) are enhanced through organic changes in body chem­istry, adap­ta­tions that favor fetal sur­vival. The cur­rent seden­tary lifestyle exag­ger­ates these meta­bolic changes and results in syn­dromes that increase the risk for a num­ber of meta­bolic, car­dio­vas­cu­lar and immuno­log­i­cal dis­or­ders of pregnancy.

When con­fronted by the idea that it is coun­ter­in­tu­itive to think exer­cise in preg­nancy might be safe (let alone ben­e­fi­cial) I am dumb­founded. To me, it is coun­ter­in­tu­itive to think that a seden­tary lifestyle in preg­nancy might be safe!

Burning Calories in Pregnancy Improves Outcomes!

Burn­ing Calo­ries in Preg­nancy Improves Outcomes!

What is the evi­dence that exer­cise in preg­nancy is ben­e­fi­cial? Keep in mind that some stud­ies have been exe­cuted more expertly than oth­ers. But, what is com­pelling is that numer­ous well-respected researchers have sought to test the hypoth­e­sis that exer­cise is not safe, but come away with results that indi­cate the opposite!

Here are some of the major findings:

• The pla­centa is larger and has more trans­port sur­face in exer­cis­ers than seden­tary women

• The fetuses of (aer­o­bic) exer­cis­ing moth­ers make ben­e­fi­cial car­dio­vas­cu­lar adaptations

• Women who do aer­o­bic exer­cise are less likely to develop severe preeclamp­sia or ges­ta­tional dia­betes, and the long term health prob­lems that accom­pany these disorders

• Women who are aer­o­bi­cally fit recover from birth 10 times faster than seden­tary women (as mea­sured by time needed to metab­o­lize free rad­i­cals pro­duced in labor)

• Women who exer­cise in preg­nancy are more likely to be phys­i­cally fit in midlife

• Babies of aer­o­bi­cally fit women are at reduced risk for pre­ma­tu­rity and low birth weight

So, we have arrived at the take-home mes­sage: MOVE!! Preg­nancy works best when you move and burn calo­ries in a mod­er­ate to vig­or­ous fash­ion. But, alter­nate this activ­ity with rest and good nutri­tion, and be sure to stay well hydrated.

Pregnancy Pathway, Conception — Health Status

Today: How the mother’s health sta­tus at the time of con­cep­tion affects the pregnancy.

For com­plete graphic, see Feb. 5 or 23 post.

The Impact of Health Status at the time of conception.

The Impact of Health Sta­tus at the time of conception.

When a woman becomes preg­nant, her health can be a major fac­tor how her preg­nancy will pro­ceed. If she has been exposed to a vir­u­lent infec­tion, it may have an impact on how well the implan­ta­tion goes. If she has meta­bolic syn­drome, she is at risk for com­pli­ca­tions such as ges­ta­tional diabetes.

On the other hand, if she has taken care of her­self, is phys­i­cally fit and well nour­ished, is well rested and has not been exposed to ill­nesses that induce dra­matic changes in her immune sys­tem, she has done her best to cre­ate a sit­u­a­tion in which her body is best pre­pared for the rig­ors of pregnancy.

There are still genetic and envi­ron­men­tal fac­tors that can affect the course of the preg­nancy, but behav­ior is the one fac­tor that women have con­trol over. At Danc­ing Thru Preg­nancy we are fond of the notion that if you know a cer­tain behav­ior is the best for a sit­u­a­tion, it is smart to chose that behav­ior; if you do not, you are sab­o­tag­ing yourself.

So, if preg­nancy is in your head­lights, eat right, exer­cise, and be cau­tious about expo­sure to ill­ness and infec­tion. Wash your hands, use one of the hand cleansers, prac­tice safe sex (okay, so if you are try­ing to get pg, this may change, but in the meantime!).

We wel­come com­ments on what you are doing to be healthy for pregnancy!

Pregnancy Pathway, Preconditions

Please refer to Feb­ru­ary 5 entry for com­plete graphic. Today we turn to the ques­tion of pre­con­di­tions to preg­nancy and how they might affect mater­nal and off­spring health.

Preconditions

Pre­con­di­tions

Pre-existing fac­tors that can influ­ence health out­comes include genetic fac­tors (fam­ily risk for heart dis­ease, for exam­ple), envi­ron­men­tal fac­tors (liv­ing in a build­ing with mold, for exam­ple), and behav­ior (eat­ing well and exer­cis­ing, for exam­ple). In each cat­e­gory, fac­tors will con­tribute to the health of the mother and even­tu­ally to off­spring health.

It is impor­tant to under­stand what major genetic fac­tors may affect your off­spring and whether the envi­ron­ment or behav­ior can help off­set neg­a­tive fac­tors. For exam­ple, there may be a his­tory of preeclamp­sia dur­ing preg­nancy in your fam­ily, but vig­or­ous aer­o­bic exer­cise in the six months prior to preg­nancy pro­vides a high degree of pro­tec­tion from this risk. Preeclamp­sia puts both mother and off­spring at risk for complications.

Other genetic fac­tors that may be of con­se­quence include autoim­mune dis­or­ders, aller­gies, and meta­bolic syn­dromes. For exam­ple, so-called “thrifty genes” may pre­dis­pose you to a high weight gain in preg­nancy. But, you may be able to off­set health prob­lems asso­ci­ated with this by stay­ing active and eat­ing well.
