Nutritionists Weigh in on Foods with Added Protein: What You Need to Know
The importance of protein in our diet cannot be overstated; it serves as a building block for muscles, bones, and skin. In an era where food companies are constantly launching high-protein versions of everything from milkshakes to granola bars, it’s easy to feel overwhelmed by the protein craze. But do we really need all these added proteins?
Why Your Body Needs Protein
Protein is one of the three essential macronutrients—along with fats and carbohydrates—necessary for optimal body function. It comprises countless proteins made from amino acids, some of which our bodies can produce, while others must be obtained from food.
“Because protein is so vital, our body has adapted mechanisms to ensure we obtain the necessary building blocks,” says Federica Amati, Nutrition Lead at Imperial College London. This means that as long as you consume adequate amounts of food, your body is likely synthesizing enough protein.
Are You Getting Enough Protein?
The World Health Organization recommends that healthy adults consume about 0.4 grams of protein per pound of body weight, totaling approximately 60 grams for men and 50 grams for women each day. In many affluent countries, the average adult far exceeds these requirements.
Amati emphasizes that protein malnutrition is rarely a concern outside of impoverished regions. “In well-off nations, most people are eating more than sufficient protein,” she explains. Nutritionist Bridget Benelam adds that variety is key: getting protein from various sources—dairy, fish, beans, nuts, and meat—provides essential micronutrients and keeps meals interesting.
The Source Matters: Animal vs. Plant Proteins
Protein can be derived from a diverse range of foods. Plant-based sources include beans, lentils, nuts, and tofu, while animal sources encompass dairy, eggs, and meat. Amati points out that animal proteins are often easier to digest than plant-based counterparts due to their lower fiber content.
However, while animal sources can pack a nutritional punch with added benefits like zinc and iron, they may also contain higher levels of saturated fat. On the flip side, plant-based proteins, such as chickpeas and beans, provide essential fiber, which many diets lack.
Do You Really Need Added Protein?
With the proliferation of protein-enriched foods, you might wonder if you should be loading up on them. Benelam advises caution. "For the average person, especially in countries like the U.S. and the U.K., it’s unnecessary to seek out additional protein,” she explains. Instead, focus on the quality of the food you consume.
Amati echoes this sentiment: "Read the ingredient labels of protein-enhanced products carefully. Many are high in sugar and unhealthy fats."
If your goal is to build muscle, Amati suggests a more straightforward approach: regular exercise. "Lifting heavier weights provides the challenge your body needs to gain strength. A protein bar alone won’t cut it."
Conclusion
In summary, while protein is crucial for your body’s overall health, you may not need to buy into the hype of protein-enhanced foods. As long as you’re consuming a balanced diet rich in various protein sources, you’re likely meeting your protein needs. Prioritize whole foods and exercise for a well-rounded approach to health.
