Oily Fish: Rich in Omega-3 Fatty Acids
Oily fish like salmon, tuna, and mackerel are packed with omega-3 fatty acids. These fats are great for fighting inflammation and boosting the immune system9.
Eating oily fish often can bring many health perks. It may lower the risk of rheumatoid arthritis, a chronic condition9. Omega-3s might also cut down the risk of breast and colorectal cancer9.
Omega-3s do more than fight inflammation and support immunity. They might help prevent age-related eye problems and diseases9. Some studies also link them to a lower risk of Alzheimer’s disease and dementia9.
To get enough omega-3 fatty acids, aim for one to two seafood servings a week, as advised by the Dietary Guidelines for Americans9. If you have heart disease, your doctor might suggest about 1 gram of EPA and DHA daily9.
Omega-3 Sources and Considerations
Oily fish are top sources of omega-3 fatty acids. But, turning alpha-linolenic acid (ALA) into EPA and DHA in the body is hard, less than 15% efficient10. So, eating whole foods is better than just taking supplements.
For example, mackerel gives you 0.59 grams of DHA and 0.43 grams of EPA per serving10. Wild salmon has 1.22 grams of DHA and 0.35 grams of EPA10. Canned sardines offer 0.74 grams of DHA and 0.45 grams of EPA per serving10.
The FDA says don’t take more than 5 grams a day of EPA and DHA from supplements, as it could affect some medicines, like blood thinners9. Pregnant or breastfeeding women and kids should eat 8 to 12 ounces of fish and seafood weekly for the best health of their babies9.
“Incorporating oily fish into your diet is a simple and delicious way to boost your omega-3 intake and support overall health.”
Cruciferous Veggies: Nutrient-Dense Powerhouses
Cruciferous vegetables are full of important nutrients and antioxidants. They help support your immune system and overall health11. This group includes broccoli, cauliflower, Brussels sprouts, and kale, among others. Studies show they’re great for your health.
Sulforaphane is a key compound in these veggies. It helps protect your heart and fight cancer12. These veggies are also high in vitamins A, C, and E, plus fiber. All these help keep your immune system strong11.
Research points to these veggies helping your brain health too. They might lower the risk of Alzheimer’s disease11. Their anti-inflammatory and antioxidant effects are good against chronic diseases like diabetes, asthma, and cancer12.
To get the most health benefits, eat a mix of these veggies and try different ways of cooking them11. Steaming is best for keeping nutrients in, but boiling can lose some13. By enjoying their crunch and variety, you can fight off diseases and boost your immune system.
“Cruciferous vegetables are packed with an array of essential nutrients and potent antioxidants that can support a healthy immune system and reduce the risk of chronic diseases.”

It can also lower diabetes and cancer risks, help with weight, and is good for those with lactose issues14. Kefir is even richer in probiotics than yogurt, making it a strong choice for gut health14.
