Want to live longer? Science says eating more protein might be the answer

In addition to affecting our weight and energy levels, our diet also affects how we age and the number of birthdays we get to enjoy. Are you surprised? Well, it is a well established fact that a healthy diet plays a crucial role in promoting longevity and overall well-being. Nutrient-rich foods support cellular function, combat inflammation, and reduce the risk of chronic diseases. However, the latest research on increased protein intake and its ability to extend life expectancy is worth noting.

A recent study by researchers at Brown University suggests that protein intake may play a key role in slowing down the aging process. The researchers concluded that a protein-rich diet could have anti-aging benefits. "Manipulating the gut hormones can help improve longevity in humans as well," the study explained.

Led by Marc Tatar, the research was conducted on fruit flies and focused on a hormone produced in their gut called Neuropeptide F. This hormone is part of the incretin family which helps with insulin production. The study found that manipulating Neuropeptide F levels could extend the lifespan of fruit flies. In humans, a similar hormone called glucagon-like peptide-1 (GLP-1) has the same function.

The connection between gut hormones and aging is linked to the interaction between the gut, brain, and other organs. When fruit flies consume protein-rich foods, Neuropeptide F is released into the bloodstream. It then travels to the brain and triggers the production of insulin-like hormones and juvenile hormones. Lower levels of juvenile hormone were found to contribute to a longer lifespan in fruit flies.

While the research was conducted on fruit flies, results suggest that regulating gut hormones in humans through protein diet could also enhance longevity and mitigate the negative effects of unhealthy diets.


Here are some interesting sources of protein to focus on for longevity:

Almonds

Almonds are a great source of vitamin E, good fats, and plant-based protein. They are a wise choice for longevity since they help reduce cholesterol and shield cells from oxidative damage.

Eggs

One of the most bioavailable protein sources is eggs, which your body can effectively absorb and utilize. Eggs, which are high in key nutrients and essential amino acids, help maintain healthy muscles and general energy.

Lentils
Lentils are an excellent choice for vegetarians and vegans because they are high in plant-based protein. They are a heart-healthy option that encourages longevity because they are also heavy in fiber and iron.

Greek yogurt

Greek yogurt offers calcium for strong bones and is a multipurpose protein source that promotes digestive health. It's a great supplement to your diet to help you keep your muscle mass as you get older.

Chia seeds

Rich in omega-3 fatty acids, which are believed to lower inflammation and support heart health, these little seeds are high in protein. You can extend your life by including chia seeds in salads or smoothies.

Paneer
Casein protein, a slow-digesting protein that aids in muscle regeneration while at rest, is abundant in low-fat cottage cheese. A longer, healthier life is facilitated by its calcium content, which also supports bone health.
