Good foods and drink!
I've tried Mangosteen juice, and the fruit in a can. Although I'm sure it's good for you, it's very sweet and expensive.
I don't know if you'd call these "superfoods"...Royal Jelly, a bee product I've used in the past from Montana, it comes in a jar and costs around $17, is great for natural energy. Of course you can't be allergic to bees or honey.
Pomegranate juice, I drink it all the time for antioxidant properties, also DARK chocolate. Nuts, they're good for the heart and inflammation. Red grapes, grape juice (no sugar), red wine are good for inflammation, antioxidant, cancer. Aloe Vera juice/gel is something I use also, I like the Lily of the Desert brand. It's good for soothing internally and can be good at times for heartburn, taken before bed.
OLIVE OIL, made a change to that years back and I feel it's VERY important to use, healthy for the heart. I use extra virgin and light, in cooking, veggies and salad.
Garlic and Onions are great for the heart and to help avoid some cancers. Tomatoes, especially cooked are good for Lycopene and men's prostate health.
Vegetables like broccoli, kale and cabbage are good for fiber and antioxidants.
Berries...especially BLUEBERRIES to me are great superfoods! I'm far from a health freak, but I believe that eating and drinking things like these really help us to stay healthy. Although there's some disease and sickness in my family, I'm over fifty and have no issues yet and I don't take any prescription medicines for anything.
PS: Almost forgot fish for Omega 3, my fav is Salmon, also citrus fruits, help keep the body alkaline.
