How to calculate the protein intake from plant base proteins?

As a supplier of plant-based proteins, I've witnessed a significant surge in the demand for plant-derived protein sources. More and more people are turning to plant-based diets for various reasons, including health, environmental concerns, and ethical considerations. However, one common question that arises is how to accurately calculate the protein intake from these plant-based protein sources. In this blog post, I'll guide you through the process and provide some practical tips.

Understanding Protein Content in Plant-Based Sources

The first step in calculating protein intake is to understand the protein content of different plant-based protein sources. Plant proteins vary widely in their protein concentration. For example, Rice Protein Isolate 80% is a highly concentrated source, with 80% of its weight being protein. This means that for every 100 grams of rice protein isolate, you're getting 80 grams of pure protein.

On the other hand, Lentil Protein Concentrate 60% has a protein concentration of 60%. So, in 100 grams of lentil protein concentrate, there are 60 grams of protein. And High Quality Textured Soy Protein also offers a substantial amount of protein, but the exact percentage can vary depending on the specific product.

Factors Affecting Protein Absorption

It's not just about the amount of protein in the food; the body's ability to absorb and utilize that protein is also crucial. Several factors can affect protein absorption from plant-based sources.

• Anti-nutrients: Some plant foods contain anti-nutrients like phytates and tannins, which can bind to proteins and reduce their absorption. For example, whole grains and legumes are rich in phytates. However, soaking, sprouting, or fermenting these foods can help reduce the levels of anti-nutrients and improve protein absorption.
• Amino acid profile: Plant proteins are often considered "incomplete" because they may lack one or more essential amino acids. However, by combining different plant protein sources, you can create a complete amino acid profile. For instance, combining rice (low in lysine but high in methionine) with beans (high in lysine but low in methionine) can provide all the essential amino acids your body needs.

Calculating Protein Intake

To calculate your protein intake from plant-based proteins, you need to follow these steps:

1. Determine your protein needs: The recommended daily protein intake varies depending on factors such as age, gender, activity level, and overall health. For a sedentary adult, the general recommendation is about 0.8 grams of protein per kilogram of body weight. However, athletes, pregnant or breastfeeding women, and people recovering from illness may need more protein.
2. Identify the plant-based protein sources you're consuming: Make a list of all the plant-based protein foods you eat in a day, including protein supplements.
3. Check the protein content: Look at the nutrition labels of the foods or refer to reliable nutritional databases to find out the protein content per serving.
4. Calculate the protein intake from each source: Multiply the number of servings of each plant-based protein source by the protein content per serving.
5. Sum up the protein intake: Add up the protein intake from all the plant-based protein sources to get your total daily protein intake from plant proteins.

Let's take an example. Suppose you're a 70-kilogram sedentary adult. Your recommended daily protein intake would be 0.8 x 70 = 56 grams.

In the morning, you have a smoothie made with 30 grams of Rice Protein Isolate 80%. The protein content in this serving is 30 x 0.8 = 24 grams.

For lunch, you have a lentil salad with 50 grams of Lentil Protein Concentrate 60%. The protein from the lentil concentrate is 50 x 0.6 = 30 grams.

In total, your protein intake from these two sources is 24 + 30 = 54 grams, which is close to your recommended daily intake.

Tips for Meeting Protein Needs with Plant-Based Diets

• Diversify your protein sources: Don't rely on just one or two plant-based protein sources. Include a variety of beans, lentils, nuts, seeds, whole grains, and protein supplements in your diet to ensure you're getting a wide range of amino acids.
• Use protein supplements wisely: Protein supplements like rice protein isolate and lentil protein concentrate can be a convenient way to boost your protein intake, especially if you have a busy lifestyle or have difficulty meeting your protein needs through whole foods alone.
• Plan your meals strategically: As mentioned earlier, combining different plant protein sources can create a complete amino acid profile. Plan your meals to include complementary proteins, such as rice and beans, or hummus (made from chickpeas) with whole wheat pita bread.

Conclusion

Calculating protein intake from plant-based proteins is not as complicated as it may seem. By understanding the protein content of different plant-based sources, considering factors that affect protein absorption, and following the steps outlined above, you can easily meet your protein needs on a plant-based diet.
