I love lentils! Not only only are they a great source of fiber and protein but packed with heart healthy vitamins and minerals too. They can be swapped out for meat on your next Meatless Monday (or try half meat, half lentils). They're great in tacos, stuffed peppers, curry, veggie burgers, salads, meatloaf, etc.
Like I said, they're an awesome source of fiber. (If a diet higher in fiber is new to you, introduce fibrous foods slowly to ease in your digestive system.) Soluble fiber in particular can help to reduce the absorption of cholesterol in our bloodstream and lower our LDL ('bad') cholesterol. Lentils are also a good source of folate and magnesium, both associated with a healthy heart.
Think beyond the Quaker packet! Oatmeal is incredibly versatile and is another excellent source of fiber (see above), especially beta-glucan. Beta-glucan can help to reduce LDL and total cholesterol, lower blood sugar, and promote the growth of good gut bacteria. Like other whole grains, oats are a great source of B vitamins. Folate and B6 in particular, have also been shown to reduce the risk of heart disease. Oats are also known for their avenanthramides - a unique group of antioxidants - an anti-inflammatory compound which may help to lower blood pressure.
The instant packets can be a great option if that is what you like, but they often include additional sugars and ingredients that aren't totally necessary. I would recommend the whole oat options (Old Fashioned, Steel Cut, etc.) for the most nutritional bang for your buck. Have you tried savory oats or overnight oats? They are great with a runny egg and some veggies, or topped with nuts and seeds (omegas, protein, and more). They can also be added to other baked goods or homemade granola bars or can act as a great whole grain alternative to processed bread crumbs.
Out of the most commonly consumed fish, salmon has the highest concentration of Omega-3 fats. Omega-3s help to lower triglycerides (fatty acids in our bloodstream that may contribute to clotting). Note that fish oil supplements have not been shown to have the same benefits as actually consuming fish. The American Heart Association recommends eating fish 2x/week for the optimal heart healthy benefits.
Salmon is also one of the best food sources of Vitamin D. Research is now showing a link between low levels of vitamin D and heart disease (mark my words, Vitamin D will be BIG this year!) *Please consult your MD or RD before beginning any supplement.
(You can also try walnuts & chia seeds for more omega-3s, and cow's milk for vitamin D)
Avocados are a staple in my house. They are a great source of monounsaturated fats which can help to improve LDL levels. By replacing saturated fats with monounsaturated fats (think Mediterranean diet) you are doing wonders for your long term heart health. Avocadoes are also a great source of fiber (see above), potassium, and vitamin E (an antioxidant!). Many of us do not get enough potassium. Potassium is an electrolyte and is essential for muscle contraction. It can help to lower blood pressure by lessening the effects sodium has on blood pressure.
Try substituting some of the butter on your toast with avocado; swapping some of the oil in your baked goods with pureed avocado; or including avocado slices on salads or sandwiches.
I'll be honest, I HATED tomatoes as a kid. It wasn't until the past few years I actually started eating them and still I prefer them cooked or canned over raw. Now, canned tomatoes are actually a staple in my house. I add them to soups, sauces, curries, and more.
Like many other fruits, tomatoes are a great source of antioxidants (specifically vitamins A and C), helping to fight free-radicals and reduce inflammation and prevent chronic disease. Tomatoes are also high in lycopene. Studies have shown many potential benefits of lycopene including: lowering LDL, antioxidant properties, acting as a potential blood thinner, as well as reducing the risk of coronary artery disease and heart disease.
