It would be interesting to be a fly on the wall in some of these "mostly vegetarian" households.
I would expect along with an increase in vegetarian eating, there'd be a spike in eating vegetables. But it may not quite be the case.
Countdown reports a growth in vegetarian and vegan protein replacement products (tofu, tempeh and Quorn) of over 13 per cent in the past year. Vegetable sales have not had a corresponding increase.
Are some people giving up meat, but not eating more veges? It is entirely possible to have an unhealthy vegetarian diet, just as it's possible to be an unhealthy vegan, paleo or carnivore.
Going vegetarian is about much more than giving up meat and animal products. It's also, really importantly, about celebrating vegetables.
It's a typical trap many young people fall into. They stop eating meat without really thinking about how to replace it healthily.
If we simply increase intake of refined carb-based foods, or junky but vegetarian snacks, we won't be any healthier - and could put our health at risk.
What's your view? letters@hos.co.nz
A healthy vegetarian diet is not difficult, but it does need thought and a good understanding of what our bodies need.
Protein can be an issue for people giving up meat. Meat gives us complete protein. Plants don't. Most plant proteins lack one or more of the essential amino acids. But it's possible to get enough protein from plants by eating a range of sources of protein such as pulses, whole grains and soy.
Speaking of soy, you don't have to embrace tofu but I love it and think it's hugely underrated by most Kiwis.
Perhaps that's another column.
