Protein has certainly become a buzzword in the health and wellness sphere, with high-protein diets frequently lauded for their potential to enhance satiety, aid in weight management, and boost athletic performance. It’s a nutrient that plays a fundamental role in our bodies, as highlighted by the Heart Foundation. They emphasise that protein is crucial for the development and repair of muscles and bones, serves as an energy source, and underpins overall well-being, including the health of our cardiovascular system. However, they also wisely point out that not all protein sources have the same impact on heart health.
To navigate this, we can turn to insights from experts like Dr. Nieca Goldberg, a distinguished cardiologist and clinical associate professor at the NYU Grossman School of Medicine. Dr. Goldberg shares her preferred protein-rich foods that not only contribute to a balanced diet but also actively support cardiovascular health.
Cardiologist’s Picks for Heart-Healthy Protein
Dr. Goldberg often recommends incorporating foods like peanut butter and nuts into one’s diet. Among nuts, almonds stand out due to their favourable balance of beneficial fats and protein. In fact, almonds are among the nut varieties that pack the most protein, offering approximately 6 grams per ounce.
Fish is another cornerstone of Dr. Goldberg’s protein recommendations. She highlights its rich omega-3 fatty acid content. “Fish is very rich in omega-3 fat,” she states. “I bake or broil the fish, because it’s not only the protein you’re eating, but how you prepare it, for sure.” She also mentions including chicken in her diet, typically prepared by baking.
The Broader Health Benefits of Protein
Beyond its role in fitness, registered dietitian Rachael DeVaux underscores protein’s importance as a daily health nutrient. She explains that protein is vital for supporting immune function, the production of hormones, maintaining stable blood sugar levels, promoting healthy ageing, and preserving muscle mass. DeVaux encourages people to view protein not just as a tool for athletic pursuits but as an essential component of everyday health.
The American Heart Association (AHA) offers clear guidance on protein consumption, advocating for a dietary approach that prioritises plant-based sources, regular inclusion of fish and seafood, and the selection of lean, unprocessed meats or poultry.
The Power of Plant-Based Proteins and Fish
The AHA points out that plant-based proteins are typically low in or free from saturated fat and are excellent sources of dietary fibre. Furthermore, consuming unsalted nuts and seeds can contribute to lowering cholesterol levels. A significant 2024 study indicated a compelling link between a higher ratio of plant-to-animal protein intake and a reduced risk of cardiovascular disease by 19%, and a 27% lower risk of coronary artery disease.
The beneficial omega-3 fatty acids found abundantly in certain fish species like anchovies, herring, mackerel, salmon, and sardines are recognised by the AHA for their potential to mitigate the risk of heart failure, coronary heart disease, cardiac arrest, and the most common form of stroke.
Practical Steps Towards Healthier Protein Choices
For individuals looking to make heart-healthy protein choices, the Heart Foundation suggests a focus on plant-based options such as beans, chickpeas, lentils, tofu, nuts, and seeds, alongside fish and seafood.
While peanut butter is often associated with high protein content, providing around 7 grams per two tablespoons, it’s also important to be mindful of its fat content, which can contribute to a higher calorie count. Dietitians advise that peanut butter can still be a healthy addition to the diet when consumed in moderation.
