A recent New York Times article highlighted research suggesting that getting more of your protein from plants — rather than animal sources — may help you live longer. It’s an idea that’s gaining ground across nutritional science. People who replace some of their animal protein with legumes, nuts, seeds, and whole grains tend to show lower rates of cardiovascular disease and all-cause mortality. But what’s really behind this?
It’s not that a piece of fish or an egg is “bad.” Protein itself is essential — for muscle repair, enzyme production, hormone balance, and immune health. What matters is the company it keeps.
When protein arrives packaged with fibre, antioxidants, polyphenols, and healthy fats, it supports your microbiome, helps regulate inflammation, and steadies blood sugar. When it comes mainly with saturated fats, processed salts, and few plant compounds, the long-term picture is less favourable.
Think of it this way:
-
A handful of lentils brings fibre, magnesium, iron, and resistant starch that feed beneficial gut bacteria.
-
A serving of tofu or tempeh carries phytoestrogens that can help modulate hormones.
-
Nuts and seeds deliver amino acids along with the omega-3 fats that calm inflammation.
From a movement and recovery perspective, plant-based proteins may also promote faster repair and lower oxidative stress, particularly when combined with colourful vegetables and adequate sleep.
That said, balance matters. Complete amino acid profiles are easier to achieve when we mix plant sources or include occasional fish or eggs, especially for those training regularly or managing higher protein needs. The point isn’t perfection. It’s diversity and quality.
In practice, the body often responds beautifully when people begin eating a more varied, colourful, fibre-rich diet: energy steadies, inflammation markers drop, and sleep improves. Whether or not one chooses to be vegetarian or vegan, the message from the research is consistent — plants belong at the centre of the plate.
