Fish oil
Omega-3 fatty acids eicosapentaenoic acid and docosahexaenoic acid are known primarily for lowering harmful blood fats called triglycerides. They can also help to mildly lower blood pressure. A daily dose of 1 gram can help with blood pressure, but 2-4 grams is recommended for lowering triglycerides. If you are already taking a blood thinner, talk to your doctor before starting to take fish oil as it can increase bleeding risk in these situations.

CoQ10
Typically combined with niacin (vitamin B-3), CoQ10 can help to minimize side effects from cholesterol lowering statin drugs like muscle weakness. It can also help to enhance the energy production in cells, and inhibit blood clot formation. Typical dose is 50-100 milligrams daily.

Red yeast rice
Available in tablet, capsule, powder, and liquid forms, this is an extract of red yeast that is fermented onto rice. It has long been used by the Chinese, and it can mimic the same actions as statin drugs for lowering cholesterol. Average dose is 600 milligrams, twice a day, but can be enhanced with combined with naturally occurring plant sterols. These can be found in small amounts in fruits and vegetables, but also in supplement form. Add 400 milligrams of these for best benefits.

Lycopene
Found in tomatoes, watermelon, pink grapefruit, red bell peppers, and papaya, this phytochemical can be helpful in lowering blood pressure. Research has proven it can lower systolic (top) blood pressure by 10 points, and diastolic (bottom) blood pressure by up to 4 points. It is a potent antioxidant, and has even been thought to have cancer preventing properties, but they have not been proven. 10 milligrams daily is the average dose.

Watermelon
The high liquid content of watermelon, along with the natural sugars and fiber, make it the perfect snack. However, it’s much more than just a snack. Tomatoes are highly touted for their high content of the immune strengthening antioxidant lycopene. The fact is that watermelon actually contains more lycopene (40% actually) than tomatoes. If you bring one home, keep it out even once it’s cut instead of refrigerating it. This may sound strange, but you get the most benefit this way. Room temperature watermelon can continue producing antioxidants for up to two weeks.

Onions
Primarily used for seasoning, onions are high in vitamin C, fiber, folate, and vitamin B-6. They also contain large amounts of quercetin, which can help relieve allergies and has also been known to have anti-cancer effects. Studies have shown that people who eat the most onions can reduce their risk for oral cancer by 84%, colon cancer by 56%, breast cancer by 25% and prostate cancer by 71%. Red onions have the most quercetin, but pink shallots have a wider mix of antioxidants.

Lettuce
Looking at the light green color of most lettuce would generally lead one to believe that it doesn’t have the nutrients of other vegetables, but this is not the case. Iceberg lettuce contains lutein and zeaxanthin, which are carotenoids that reduce the risk of cataracts and age related macular degeneration. Add a salad at the beginning of a meal to get some of these benefits, and you’ll also likely eat fewer overall calories due to feeling more full and satisfied.
