In recent years, protein powder has gained significant traction among women as a dietary supplement. Despite some lingering stereotypes and misconceptions, its benefits extend far beyond bodybuilding.
This article aims to delve into the world of protein powder for women, dispelling myths and highlighting its role in supporting your overall health and fitness. We’ll also explore the emergence of plant-based options, offering insight into the diverse landscape of protein supplementation available.
Why do women need protein?
Women need protein to combat fatigue, keep muscle mass to avoid metabolic syndrome and cardiovascular disease, and keep you independent and strong as you age.
Making sure you get enough protein is especially important for you as a woman. Your hormonal changes can sometimes cause your body to break down muscle instead of building it, depending on where you are in your menstrual cycle or if you’re going through menopause.
Pay close attention to your protein intake after ovulation and during the luteal phase, when your progesterone levels rise. Progesterone breaks down protein to provide amino acids needed for the uterine lining. To counteract this, you need slightly more protein to maintain your muscle mass.
As you enter perimenopause and postmenopause, your hormone levels fluctuate and decrease, leading to a loss of the muscle-building stimulus provided by estrogen. Therefore, you’ll need more protein to make up for this loss. Additionally, as you age, research suggests that you’ll need more protein to achieve the same training results.
The importance of amino acids
Before discussing the different types of protein powders, it’s important to understand how our body uses amino acids to break down protein to repair and grow new muscle fibers.
Amino acids are like the pieces of a puzzle that build protein. These proteins, each made up of long chains of amino acids, play crucial roles in your body. Each protein has its unique sequence of amino acids, which determine its shape and function, similar to how different combinations of letters form words.
So, just as letters come together to create various words, amino acids combine to form different proteins in your body.
Nine essential amino acids
Animal and plant proteins contain around 20 amino acids necessary for building body protein and other important compounds like creatine, hormones, and neurotransmitters.
There are nine essential amino acids: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Each plays different but equally vital roles in maintaining the body’s functions.
Some amino acids, like histidine, phenylalanine, and tryptophan, help produce neurotransmitters that regulate various bodily functions such as immunity, appetite, digestion, mood, and sleep patterns. Others, like threonine, lysine, and methionine, are crucial for skin health, collagen production, metabolism, and detoxification.
Three amino acids, collectively known as branched-chain amino acids (BCAAs), are particularly important for building muscle.
Whole proteins contain a complete amino acid profile necessary for the body. These foods encompass a variety of options, such as:
- Beef
- Poultry
- Fish
- Eggs
- Dairy
- Soy
- Quinoa
- Buckwheat
Conversely, incomplete proteins lack some essential amino acids. Foods that fall into this category include nuts, seeds, beans, and certain grains.
For individuals following a vegetarian or vegan diet, it’s important to include a variety of incomplete proteins to ensure the intake of all nine essential amino acids.
Types of protein powders
Protein powders come in two main types: animal-based and plant-based. Let’s start with animal proteins.
Whey protein powder
Milk consists of two proteins, casein and whey. Whey protein can be separated from the casein in milk or generated as a by-product during cheese production. It’s classified as a complete protein because it contains all nine essential amino acids the body needs. Additionally, whey protein has a low lactose content and gives you around 24 grams of protein per scoop (depending on the brand). However, there are different kinds of whey protein.
- Whey protein concentrate: This concentrate contains 30-80% protein and up to 50% lactose. It’s good if you’re not super active and just want to boost your protein intake.
- Whey protein isolate: It contains less than 1% lactose and at least 90% protein. It’s a great choice if you’re really active. It helps build muscles without adding a lot of calories, making it perfect for before or post-workouts.
- Whey protein hydrolysate: This type is highly processed and less common. It’s mainly used in medical supplements and baby foods.
Casein protein powder
Casein protein, responsible for milk’s white appearance, constitutes approximately 80% of cow’s milk. Beyond milk, it’s also in yogurt, cheese, infant formulas, and numerous dietary supplements.
Rich in essential amino acids crucial for muscle development, casein protein is digested slower than other proteins. This characteristic may contribute to its potential to curb appetite and enhance feelings of satiety. With about 25 grams of protein per serving (again, depending on the brand)it’s best taken at night or in the morning.
For those who prefer plant-based options:
Pea protein powder
Pea protein, sourced from green and yellow split peas, is commonly utilized to create protein powder. It’s a foundational ingredient in various packaged foods, including veggie burgers, vegan mayo, and dairy alternatives like ice creams and milk.
The legume boasts a natural protein content of 11 grams per quarter cup, making peas an excellent vegan protein source. This makes them an ideal choice for individuals following a plant-based diet seeking to increase their protein intake.
Based on the brand, a typical serving of pea protein powder provides approximately 90 to 120 calories and 17 to 24 grams of protein. This makes it comparable to other protein powders in terms of nutritional content. However, it’s important to note that flavored versions may contain added sugars.
Soy protein isolate
Soy protein isolate is essentially soybean protein that has been separated from other components through chemical processes. To achieve this, soybeans are washed with an acid and neutralized using an alkaline solution.
Once the soy protein isolate (SPI) production process is complete, you obtain a dry powder containing approximately 90-95% protein and minimal carbohydrates and fats.
Given its high protein content, this plant-based powder is commonly incorporated into various packaged foods, ranging from protein bars to veggie burgers. Additionally, it can be seamlessly blended into smoothies for added nutritional value.
Other vegan protein powders
In addition to soy and pea protein powders, several other vegan-friendly options are available, including brown rice, egg whites, and hemp protein powders. Each of these alternatives offers its own unique set of nutritional benefits.
Brown rice protein powder
Although this protein isn’t as common as its soy and pea counterparts, it’s a great source of protein. Using it as a supplement to maintain a balanced diet can ensure you get all nine essential amino acids the body requires.
Researchers evaluated the amino acids present in brown rice protein compared to soy and whey proteins and concluded that it can adequately substitute for soy or whey protein.
Egg white protein powder
Egg white powder boasts a wealth of nutritional benefits, serving as a significant protein source and showcasing versatility in various culinary uses. Introducing egg white powder into your dietary regimen can aid in achieving fitness objectives, facilitating muscle recuperation, weight management, and streamlining daily routines.
Its prolonged shelf life and allergen-friendly properties further underscore its practicality for anyone committed to a balanced and health-conscious lifestyle.
Hemp protein powder
Hemp protein, derived from the cannabis plant, offers a rich source of plant-based protein without any THC, the psychoactive compound found in marijuana. Highly sustainable, hemp can thrive in diverse climates, and its various parts serve multiple purposes.
Historically, hemp seeds have served as a vital medicinal and food source for thousands of years, providing protein, fiber, and medicinal benefits across Europe, Africa, China, and Japan.
Hemp seeds can be consumed in two forms: shell-free or ground into a powder, both offering abundant nutrition and numerous health advantages. Whether you follow a plant-based diet or not, hemp protein can serve as a valuable addition to your dietary routine.
Myths vs. Facts about protein powder for women
When it comes to protein powder for women, there are many myths swirling around. Let’s clear up some common misconceptions:
Myth: Protein powder will make you bulky.
Fact: Protein powder can help build lean muscle, but it won’t make you bulky unless combined with intense weightlifting and a high-calorie diet.
Myth: Protein powder is only for bodybuilders.
Fact: Protein powder is beneficial for women of all fitness levels, helping with weight management and overall health.
Myth: Plant-based protein powder is inferior to animal-based protein.
Fact: Plant-based protein powder can be just as effective and is often easier to digest, making it a great option for women with dietary restrictions or preferences.
Myth: Protein powder is only necessary if you’re not getting enough protein from food.
Fact: While protein powder can supplement your diet, it’s not a replacement for whole food sources of protein. It can be convenient for busy lifestyles or post-workout recovery, but it shouldn’t be relied upon exclusively for protein intake.
By separating fact from fiction, you can make informed choices about incorporating protein powder into your routine, ensuring you reap its benefits without falling victim to common misconceptions.
Choosing the best protein powder for your needs
When selecting a protein powder, consider your specific needs and goals. Here’s a breakdown to help you make the best choice:
- If you want to build muscle: Opt for protein powders with a high biological value, such as whey protein or whey isolates, to support muscle growth effectively.
- If you want to lose weight: Look for shakes without added sugars or dextrins/maltodextrins, as these can contribute to weight gain. Avoid options with added branched-chain amino acids (BCAAs) that promote muscle growth.
- If you are vegetarian or vegan: If you follow a vegetarian or vegan diet, choose plant-based protein powders like soy, pea, or hemp, avoiding milk-based options.
- If you are diabetic: For individuals with diabetes, select protein shakes without added sugar and low carbohydrate content (5-15 grams per serving) to manage blood sugar levels effectively.
- If you need to limit protein for kidney disease: Those with kidney disease should opt for protein powders with lower protein content (10 to 15 grams per serving) to avoid strain on the kidneys.
- If you want to avoid gastrointestinal issues: If you have irritable bowel syndrome, lactose intolerance, or gluten sensitivity, opt for powders free from lactose sugars, artificial sweeteners, dextrins/maltodextrins, or gluten to prevent digestive discomfort.
