These threads about what is "allowed" confuse me. Anything is allowed. Even oil, met, dairy etc.. Before anybody jumps on me, let me explain...
You're an adult and you can choose to eat or drink whatever you would like to. You will also face the consequences of those choices.
If you want to see the best health and the fastest, most permanent weight loss, then choose the lowest calorie dense, least processed, whole, plant foods you can find. Stock your home with them, cook at home, learn to cope with social situations, get rid of any less-than-stellar foods in your home, eat to full satisfaction. Keep your seasoning to herbs and spices, and completely avoid all meat, dairy, oil, nuts, seeds, juice/wine, sugar, refined foods, flours etc..
If your goal is to see if you can eat a bit healthier and you hope to lose a few pounds (maybe), you can achieve that by eating all sorts of less-than-stellar foods (ie. nuts/seeds/avocado on the healthier side, processed foods and oils and refined foods on the unhealthy side).
Some people can eat a lot of less-than-stellar foods and get decent results. Good for them. Some people can just look at a peanut and gain a pound. Bad for them...except that maybe they'll have more motivation to make stellar food choices and will enjoy better health in the years to come.
My point is, please don't look for permission from anyone in terms of what you're allowed to eat.
If you want to be the healthiest, thinnest version of yourself you can be, choose MWL and low-calorie dense, nutritient-rich food and don't compromise.
If your goal is not that lofty, then choose whichever point on the spectrum between SAD and MWL that you are comfortable staying at. Go ahead and include the wine, olives, bread etc..- whatever you believe you can't live without. Just don't come back here in six months and complain that you are not the healthiest, thinnest version of yourself.
Accept that you are responsible for the consequences of your dietary choices, decide which kind of results you will set as your goal, eat the foods that will get you there, and stop looking for loopholes. There are none.
