Throw ½ cup (or about 75 g) of fresh or frozen blueberries into your morning rotation—blend them with spinach and Greek yogurt for a sweet smoothie, or use them as a topping for oatmeal.
For a snack, you can combine them with some almonds (or other nuts).
Try to eat blueberries at least 4–5 times per week for more reliable results.
Whenever possible, select organic blueberries to limit exposure to pesticides.
Steer clear of sweetened or strained blueberry juices—they lose the fiber and can cause blood sugar to rise.
Apples: Fiber and Polyphenols for a Healthy Liver

The apple, despite its status as a household staple found in kitchens worldwide, is much more than a regular fruit. High in pectin (a soluble fiber) and polyphenols, it supports liver function and helps maintain major metabolic markers in check.
Studies suggest that regular apple consumption may be associated with lower levels of liver fat and triglycerides, particularly in people who are overweight. Pectin binds to fat and cholesterol in the gut, preventing their absorption, while polyphenols such as quercetin shield liver cells from oxidative damage. Apples may also help control blood sugar by slowing the digestion and absorption of carbohydrates.

Even beyond this liver-friendly link, apples help with satiety and easing the burden of nonalcoholic fatty liver disease, which is a feather in their health cap. With a low glycemic index, they make a savvy choice for individuals with diabetes, while their impact on increasing high-density lipoprotein (HDL) (“good”) cholesterol benefits cardiovascular health.
Eat a whole apple (skin and all, since that’s where most of the polyphenols are) as a snack or light dessert. Bake apples with cinnamon for a healthy treat, or grate apple into carrot and walnut salads. Try to eat one or two apples a day; opt for high-fiber types such as Granny Smith or Fuji. Avoid overly sweet compotes, which leach out micronutrients.
Avocados: Healthy Fats for Your Metabolism

Avocados offer plenty of monounsaturated fats, fiber, and vitamin E, making them an important part of any liver-supporting and heart-healthy eating plan.
