Trying to become more healthy but everything is bad nowadays.

How should we eat? Should I just keep eating as is if I've never had any major issues? Carnivore seems great for some bad for others. Plants are toxic. Grains are bad. Then flip all these.

Only real definitive thing I can gather is sugar and lot of carbs from like cakes and pancake type foods and French fries are probably bad . So hard to know what's healthy anymore
