The "rule of 5 fruits and vegetables," often called "5 A Day," encourages eating at least five portions of a variety of fruits and vegetables daily (around 400g total) to reduce the risk of serious health issues like heart disease, stroke, and some cancers, providing essential fiber, vitamins, and minerals. A standard portion is about 80g, which can be a medium piece of fruit, half a cup cooked vegetables, or one cup raw leafy greens, with options including fresh, frozen, canned, or dried.
At a glance: what counts? 80g of fresh, canned or frozen fruit and vegetables counts as 1 portion of your 5 A Day (but not potatoes and some other starchy foods).
Michael Pollan's core eating rules, summarized as "Eat food, not too much, mostly plants," distill into several actionable guidelines, including avoiding processed items your great-grandmother wouldn't recognize, shopping the supermarket perimeter, not eating things that won't rot, paying more for better food, eating meals at a table with others, and stopping when 80% full. These rules emphasize whole foods, traditional eating patterns, and mindful consumption over processed convenience.
The United States stopped using the pyramid model for dietary suggestions in 2011 when it moved to a visual that more closely resembled a dinner plate. The RFK Jr.-led Department of Health and Human Services has returned to the familiar relic of the '90s and 2000s, effectively turning it on its head.
While there's no single "number 1" healthiest fruit, blueberries are consistently ranked at the top for their exceptional antioxidant power (anthocyanins), supporting brain health, heart function, and potentially reducing inflammation and risk of chronic diseases like type 2 diabetes and heart disease. Other top contenders include avocados for healthy fats and fiber, raspberries for fiber, and pomegranates for antioxidants, but blueberries often stand out as a top choice.

The Australian government guidelines now use the Eatwell Plate as a replacement for the 1980s Food Pyramid. This is also part of the Aussie Guide to Healthy Eating, as we have mentioned. The five main food groups of the Eatwell Plate, include: Carbohydrates.
The 3-3-3 rule for weight loss is a simple, habit-based method focusing on three key areas: 3 balanced meals a day, 3 bottles (or ~1.5L) of water by 3 PM, and 3 hours of physical activity per week, aiming for consistency over complex diets. It simplifies fat loss by establishing rhythm through consistent eating, adequate hydration to support metabolism, and regular movement, promoting sustainable health without intense calorie counting or restrictive rules, says Five Diamond Fitness and Wellness, Joon Medical Wellness & Aesthetics, and EatingWell.

Tinned or frozen fruit
A portion is roughly the same quantity of fruit that you would eat for a fresh portion, such as 2 pear or peach halves, 6 apricot halves, 8 segments of tinned grapefruit, or 2 handfuls (4 heaped tablespoons) of frozen blueberries. Choose fruit canned in natural juice, rather than syrup.
The best tinned fruits to try
A peanut butter and jelly sandwich (PB&J) adds about 33 minutes to your healthy lifespan per serving, according to a University of Michigan study that measured life expectancy impacts of over 5,850 foods using the Health Nutritional Index (HNI). This sandwich tops the list for adding time, with nuts and seeds also being highly beneficial (around 25 mins) and processed items like hot dogs subtracting time.
Dark green, leafy vegetables may all be considered superfoods, but many think kale wins the prize for its high levels of vitamins C and K – needed for normal bone function and blood clotting. Kale also contains lutein and zeaxanthin, two nutrients thought to be important for eye health.

Each week, you'll buy five different vegetables, five fruits, four grains, three proteins, two dairy items, two spreads or condiments, and one fun treat.
For example, the loss of water might make you feel a little lighter, but you're not getting rid of belly fat. It's just a loss of water. Try to choose an eating pattern that you can maintain over time. Even if you lose a few pounds on a 3-day cleanse or fast, these types of diets aren't sustainable over a long period.
Fruits with the highest amounts of sugar: Besides dried fruits, some fruits contain high amounts of sugar you might want to avoid. For example, a cup of fresh, chopped dates contains 101 grams of sugar, a cup of raw lychee contains 29 grams of sugar, and mangoes contain 22.5 grams of sugar.
Watermelon can help reduce your body fat and waist circumference due to its high water content. Watermelon is also rich in vitamins A and C, which can help with skin health and metabolism.
