Plant-based protein sources, including legumes, whole grains, and nuts, have been linked to a reduced risk of cardiovascular diseases. They often contain heart-healthy fats, omega-3 fatty acids, and other nutrients that can help improve cholesterol levels and promote cardiovascular health.
Meeting protein needs on a plant-based diet
Recommended protein intake
The recommended daily intake of protein varies depending on factors such as age, sex, activity level, and overall health. However, a general guideline is to consume around 0.8 grams of protein per kilogram of body weight. This means that for a 68-kilogram (150-pound) individual, the daily protein requirement would be approximately 55 grams.
Calculating protein needs based on body weight
To calculate your specific protein needs, multiply your weight in kilograms by the recommended protein intake per kilogram. For example, if you weigh 68 kilograms, you would multiply this by 0.8 grams of protein, resulting in a daily protein requirement of 55 grams.
Combining plant-based protein sources for complete amino acid profile
By combining different plant-based protein sources, you can ensure a complete amino acid profile. For example, pairing legumes with whole grains creates a complementary amino acid profile that supplies all the essential amino acids your body needs.
