Researchers have linked dietary data from over 55,000 individuals with data on the environmental impacts of the foods they eat. The team, from the Livestock, Environment and People (LEAP) project at the University of Oxford, found that the dietary impacts of vegans were around a third of those of hi...
"avoiding all animal foods may lead to nutritional deficiencies in vitamin B12, omega-3, calcium, zinc, iron, magnesium, and high-quality protein.
These deficiencies may be associated with increased risk for certain types of cancer, stroke, bone fractures, preterm birth, and failure to thrive. Avoiding consumption of animal-sourced food may also be related to higher rates of depression and anxiety. Hair loss, weak bones, muscle wasting, skin rashes, hypothyroidism, and anemia are other issues that have been observed in those strictly following a vegan diet."
Eating animal foods is also linked to increased risk of certain types of cancer, stroke, etc. It's totally possible to avoid malnutrition even on a vegan diet. It just requires some consideration.
The full paper promotes a plant-forward diet supplemented with modest amounts of nose-to-tail animal consumption. Even this paper isn't promoting the rampant consumption of animal muscle typical of western diets.
B12 is fed to animals. This is where the b12 comes from. Meat eaters are having their food supplemented also.
There are many plant foods rich in omega 3 fatty acids with good omega ratios. Such as flax, hemp seeds, and chia.
Minerals are common in plant foods, very common. For example, kidney beans and leafy greens.
The idea of vegans diets being deficient in protein is laughable and intentionally misleading. For example, beans on toast is a complete protein source.
