You might want to ease into raw diet because the increase in fiber intake from even a moderate vegan diet - unless you are used to it - can make easily cause gastrointestinal discomfort at first and also make you hit the bathroom a
lot.
There's one vitamin you have to be careful about if you stick with the vegan diet long term, and that's B12. All other vitamins, fatty acids, minerals, etc can be obtained sufficiently or even abundantly versus a non-vegan diet, but B12 (which is synthesized in nature by bacteria) is hard to come by in diet alone, though there is evidence of it in being present in fermented foods or tea like kombucha. If you are on a vegan diet past a month you should consider taking a B12 supplement.
Other than that, you can make a fairly healthy diet plan by eating a variety of fruits, vegetables, and grains. Ignore the nonsense some people spew about insufficient protein in the vegan diet, as you can easily get all amino acids you need without meat. Even "incomplete" protein sources can have enough of the essential amino acids for even someone with high daily protein requirement.
Also, I recommend going for as much leafy greens (kale, spinach, collard greens, broccoli, and others) as possible, since they tend to be extremely rich in most of the nutrients needed. After that you want a spectrum of colors when it comes to fruits and veggies, and a variety of nuts and seeds, which are rich in unsaturated fats, protein, and a balance of fatty acids.
Two general resources I like:
Nutrition Data and
WHFoods. Good ways to double check the nutrition of what you eat. Great for vegans and non-vegans alike. I've only been a vegan for a little over a year, but I plan on sticking with it for life because of what I've read and seen (the aforementioned
The China Study and several Netflix documentaries being particularly compelling). It's possible to eat a relatively healthy diet without being a vegan, but almost all research and anecdotal evidence points to diets rich in fruits, vegetables, grains, legumes, seeds, and nuts as being very healthy. For anyone who doesn't want to go to the extreme of a vegan or a vegetarian diet, I would highly recommend trying to follow a
Mediterranean diet, as there's a vast amount of research pointing to the health benefits and average longevity of people who follow that diet.
