If I continue to eat my favorite food for the most part, will I get seriously ill and die long before the age of 80 etc?

Cut all that shit out of your diet. Cut the pasta, the pizza and the rice. There are more carbs in that than Jennifer Lopez has engagements. Stop drinking fizzy drinks and anything with added sugar. You can't stick with chicken. Eat vegetables and fruit, too. Coffee is actually surprisingly okay but don't put too much sugar.

How's your blood work and whats your height? You're definitely on track to easily preventable health problems if you continue eating this way. I'm the same age as you and the made the switch to a healthier lifestyle many years ago. I'd suggest cutting out overly processed food, avoiding or limiting take out, restaurants and fried foods, eat more vegetables/fruit/whole grains and most importantly, LEARN TO COOK! I can't stress how important this is. You can still eat meat, but I'd suggest choosing lean cuts and maybe some fish.

It's possible to have tasty food that is also healthy. If you gradually switch to healthier food then your body will probably eventually lose the taste for fast food. Start with small changes, make them habits, and then work up to bigger changes. I think you will actually feel better if your diet is healthier. Also the diet you describe is missing some nutrients (do you take a multivitamin?). Cereal for breakfast sounds ok to me but it sounds like you can incorporate a lot more fruits and vegetables and less saturated fat and soda in your other meals. I think an easy way to start would be to cut down on soda, by making a promise to yourself to only drink soda on the weekends, or if that is too hard, then every other day rather than every day. Track your changes in behavior with a notebook, that will help you see patterns and troubleshoot (eg you might find you always drink more soda on Thursdays because that is the day the train is always late and you are stressed out when you get home, then you can prepare a way to deal with that). You might also try to incorporate one fruit or vegetable per day, say a tomato sandwich with lunch, or an apple a day, something like that. You can always work up from there to make things better and better, going slowly and systematically and working towards improvement rather than perfection.

If you are not allergic to walnuts, here is a delicious and healthy pasta dish:https://marisamoore.com/roasted-broccoli-walnut-pasta/

Pizza with veggie toppings is the only perfect food. Grain, dairy, veggies.

Probably the best advice is what medical doctors have advised for decades. Just eat a well balanced diet. Plus exercise.

Any processed food is bad for you. Some things are not overly processed ie. Bread, pasta, basic cereals, milk etc are not dangerous. They are just more of challenge to our digestive systems. But the more ingredients something has the worse it gets for your body. Salt and sugar are the main culprits along with hydrogenated and trans fats.

The more you can eat in as near to it's original form the better for you it is.

If you live off fast food and takeaway you are just clogging your body with sugar, fat and salt.
(And in the USA alot of additives and food colourings are banned in much of the rest of the world so they won't help people in the USA either😐)

The best way to ease yours into healthier foods is to change the way you cook them. If you like bacon and sausages, then grill them instead of frying them. Have scrambled or poached eggs instead of fried. Use as little cooking oil as you can. This way you will still be having food you like but it will be a bit better for you.

Once you've mastered this, try adding a small salad to every meal as a starter. Or boil or steam vegetables to serve with meat portion of your food instead of chips.

If you make little changes every couple of weeks you will feel the benefits almost immediately.

Like I said in my other post, cut down on salt, sugar and fat. Also try having a little walk a few times a week. Even if it's only to the end of the road and back.

When I read this - //Why is the world of food in our humanity so unfair? Why can't we eat delicious food that serves us well, why does it have to be bad for us? We are what we eat - very popular phrase. But anyways...// I just KNEW immediately that you're not really 34 years old!

Three, maybe. Or even four. But not Thirty-four!
