Is There Such a Thing as Too Much Protein? | QA

Question:

Hello LA Fitness! It seems a lot of people are mentioning Chronic Kidney Disease. I hear that this can be from a number of reasons, including consuming too much protein. If you’re on a renal diet, or have kidney disease, or want to avoid getting CKD, how much protein is too much?
– Darque O.

Answer:

Whether you need to restrict protein or not should be determined by your nephrologist, depending on the stage of your renal disease. Note that the National Kidney Foundation (NKF)  states “Low protein and calorie intake is an important cause of malnutrition in chronic kidney disease1” and “There is insufficient evidence to recommend for or against routine prescription of dietary protein restriction to slow progression of chronic kidney disease.1

The Centers for Disease Control and Prevention indicate that protein in the urine is a risk factor for developing kidney disease2. While one might assume that dietary protein load is the culprit, it’s more likely from impaired kidney filtration due to diabetes. The CDC recommends two dietary improvements: eating more fruits and vegetables while eating foods lower in salt2.

According to the National Institute of Diabetes and Digestive and Kidney Diseases, preventing diabetes and high blood pressure helps to protect your kidneys from chronic kidney disease (CKD)3. The organization advises cutting back on salt and added sugars and suggests a DASH eating plan3. Protein is not mentioned.

Managing Menopause | QA

Managing Menopause | QA

Question:

I have begun Menopause and have been gaining weight and having bad hot flashes. Is there anything you can suggest I do?

Thanks,

– Lisa D.

Answer:

 

Every woman will eventually reach the stage of menopause and the ovaries cease production of estrogen. (sigh) The transitional time, termed perimenopause, may take several years. Nutritionally, managing these stages involves responding to changing hormones and influencing energy balance.

The Physicians Committee for Responsible Medicine recommends a low-fat, vegetarian diet for women who are experiencing hot flashes. EndocrineWeb encourages “filling your meals with plenty of whole grains, fruits and vegetables.” Adequate protein is needed to support muscle-protein synthesis, with intake spread across the day. In regards to supplements, WebMD indicates that black cohosh, St John’s wort and flaxseed may help manage menopause symptoms.

Creating an energy deficit is necessary for weight loss, which can come from curbing caloric intake or boosting output. Regular exercise to the tune of 60 minutes daily also helps, particularly if it includes strength training to retain lean body mass.

What You Need to Know About Optimal Nutrient Timing | QA

What You Need to Know About Optimal Nutrient Timing | QA

Question:

I usually work out at 6 or 7 am and I want to know if it’s better to eat breakfast before or after working out. If it’s after what should I eat before working out? Thank you for your help

– Santiago C.

Answer:

Optimal eating before and after a workout is all relative to the type and extent of your morning training. Some research points to greater fat burning performing cardio in a fasted state. Yet everyone seems to have a different eating schedule that works for them. Do you feel energized by a light breakfast ahead before working out or does it leave you feeling dull? Are you ravenous after working out or do you not register any hunger then?

BEFORE (approx. 30 minutes prior)

Since you don’t have the 3-4 hours ahead of time for a full meal, you can focus on a quick energy boost to restore glycogen and prime blood sugar for working muscles. If you don’t tolerate food well first thing in the morning, choose a simple carbohydrate source such as a cup of applesauce or single serving of graham crackers/pretzels with a cup of water. Move up to a mini meal of one egg plus a slice of bread and glass of milk if you feel better with solids in your system. You can also blend up a breakfast smoothie with Greek or skyr yogurt, cracked flaxseed, berries and banana.

DURING

Don’t forget about the opportunity to consume some nutrition during physical activity. For an intense exercise bout that lasts at least an hour you may consider sipping on a glucose-electrolyte beverage, aka traditional sports drink. These provide simple sugars for energy and potassium and sodium for muscle contractions and nerve impulse stimulation, as well as hydration for temperature regulation and nutrient processing.

AFTER (within 30 minutes following)

Immediately you can eat a granola-type bar you’ve packed in your locker bag or grab a protein shake from the juice bar to start off your recovery. This time is critical to nourishing your body for the whole day. Now’s the time for a heartier meal (e.g. oatmeal, lean turkey sausage and grapefruit) or a healthy breakfast wrap of eggs, spinach, feta, salsa and wheat tortilla. Choose foods with some protein and complex carbohydrate – a little fat is okay, too!

Introduce Teens to Healthy Eating Habits | QA

Introduce Teens to Healthy Eating Habits | QA

Question:

Good morning,

I have a question about how to introduce my daughter to a better way to eat. She is 17 but loves to eat junk food, no veggies. I think the way she eats is affecting her ability to concentrate and perform in school.

Please help.

– María G.

Answer:

I’m glad you said ‘introduce’ instead of lecture, tell, instruct, etc. Teenagers seem to hardly listen to their parents, let alone experts, regarding self-care choices. Communication experts suggest giving praise for good decisions. Another approach is to discuss how food industry marketing overtly influences their food choices. Perhaps start a conversation by asking her what factors she thinks are impacting her school performance – then listen and act on those first.

Although I’ve a handful of websites* to suggest she visit (assuming she bothers to read them), most teens are influenced by their peers and social media. Sigh. Role modeling a healthy lifestyle is one of the best things you can do as a parent, letting you “teach by example.” Behaviors and choices surrounding a nutritious diet, adequate sleep and routine exercise should be a family undertaking. That includes siblings and other adults in the home too! 

Tips

  • Involve her in planning the menu, choosing recipes and creating grocery shopping lists.
  • Offer to shop for something she is willing to cook herself.
  • Keep ready-to-eat versions of fruits and vegetables readily accessible in the kitchen.
  • Limit the junk food purchased and brought into the home so it’s not available.
  • Get her active in hands-on vegetable gardening.
  • Eat together as a family.
  • Limit exposure to commercial television and don’t eat in front of the TV.

Fish Oil Absorption and Timing | QA

Fish Oil Absorption and Timing | QA

Question:

If fish oil is taken in the morning, how soon afterwards can a fiber supplement be taken without absorbing the fish oil?

– Gary J.

Answer:

My, my, someone is thinking ahead and looking to get the most bang for their supplement bucks! Shouldn’t we all? Seems that you’ve implied fiber absorbs fat present in the gut. …And you’d be right! Soluble fiber is known for binding with liver-created cholesterol (put out via bile secretion) and passing it through the gut. Fiber supplements usually contain psyllium, providing 5-10 grams soluble fiber per serving.

Now, to answer your question we would need to know the clearance time of a fish oil supplement. Hmm. That would depend on whether it’s straight oil, an emulsified liquid form, or a capsule. Whether food or beverage is also being consumed at the same time makes a difference. Therefore, I could not accurately say how long that process takes from mouth to large intestine.

The soundest advice would be to consume your fish oil and fiber supplement hours apart to prevent any interplay affecting digestion or absorption.
