Alot of people dont realize its what YOU DONT eat that makes the difference.
Most upper class people ($50k a year and up) dont eat bread. They take the buns off hamburgers/hot dogs. For certain recipes like Spaghetti, they use Zucchini Noodles. IWhen baking Pizzas they use a cauliflower crust.
Also, Wealthy households with assets totaling 250k dont consume dairy (Tony Robbins baby cow theory). If they do drink Milk, its from Goats and Sheeps or an alternative like Oat/Almond/Rice. Regular milk from Cows is responsible for skin conditions like acne, psoriasis and eczema.
Also not to get religious but most Rich People (millionaires with Paid off mortgages, Vehicles and mutual funds) dont take Fish Oil - they simply make Fish a centerpiece of their diet. They dont necessarily eat at restaurants like Pappadeaux, Red Lobster, Long John Silvers or Captain D's either - a disproportionate amount of millionaires are either Hindu, Jewish or Muslim and can't consume the swine. In the absence of Pork they compensate with Fish - Gelfite, Mussels, Clams, Oysters, Sardines, Mackerel, Sea Bass, Trout, Cod Ventresca Tuna etc. All the above i mentioned are low in mercury so u dont have to worry.
Fish Oil pills dont really make make a difference - yeah your increasing your Omega 3 but if your not actively trying to reduce your Omega 6 level its all for nothin...(the ratio is what counts).
If u dont know, most Omega 6 comes in the form of processed snacks. Ask yourself when is the last time you seen a rich Dude eating a bag of Doritos or Cheese Puffs? They eat actual meals, if they're bored in between meals they have actual hobbies like buying rare art, Real Estate or playing golf.
