It’s easy to get confused when it comes to health and nutrition.
Even qualified experts often seem to hold opposing opinions.
Yet, despite all the disagreements, a number of wellness tips are well supported by research.
Here are 27 health and nutrition tips that are actually based on good science.
Sugary drinks are among the most fattening items you can put into your body.
This is because your brain doesn’t measure calories from liquid sugar the same way it does for solid food (
Keep in mind that certain fruit juices may be almost as bad as soda in this regard, as they sometimes contain just as much sugar. Their small amounts of antioxidants do not negate the sugar’s harmful effects (
Despite being high in fat, nuts are incredibly nutritious and healthy.
They’re loaded with magnesium, vitamin E, fiber, and various other nutrients (
Additionally, your body doesn’t absorb 10–15% of the calories in nuts. Some evidence also suggests that this food can boost metabolism (
Processed junk food is incredibly unhealthy.
They’re usually low in fiber, protein, and micronutrients but high in unhealthy ingredients like added sugar and refined grains. Thus, they provide mostly empty calories.
Coffee is very healthy.
It’s high in antioxidants, and studies have linked coffee intake to longevity and a reduced risk of type 2 diabetes, Parkinson’s and Alzheimer’s diseases, and numerous other illnesses (
Fish is a great source of high-quality protein and healthy fat.
The importance of getting enough quality sleep cannot be overstated.
What’s more, poor sleep is one of the strongest individual risk factors for weight gain and obesity. One study linked insufficient sleep to an 89% and 55% increased risk of obesity in children and adults, respectively (
The bacteria in your gut, collectively called the gut microbiota, are incredibly important for overall health.
Good ways to improve gut health include eating probiotic foods like yogurt and sauerkraut, taking probiotic supplements, and eating plenty of fiber. Notably, fiber functions as fuel for your gut bacteria (
Drinking enough water can have numerous benefits.
Surprisingly, it can boost the number of calories you burn.
The optimal time to drink it is before meals. One study showed that downing 2.1 cups (500 ml) of water 30 minutes before each meal increased weight loss by 44% (
Meat can be a nutritious and healthy part of your diet. It’s very high in protein and contains various important nutrients.
However, problems occur when meat is overcooked or burnt. This can lead to the formation of harmful compounds that raise your risk of cancer (
When you cook meat, make sure not to overcook or burn it.
One strategy is to use a pair of amber-tinted glasses that block blue light from entering your eyes in the evening.
Sunlight is a great source of vitamin D.
Yet, most people don’t get enough sun exposure.
In fact, about 41.6% of the U.S. population is deficient in this critical vitamin (
If you’re unable to get adequate sun exposure, vitamin D supplements are a good alternative.
Vegetables and fruits are loaded with prebiotic fiber, vitamins, minerals, and many antioxidants, some of which have potent biological effects.
Eating enough protein is vital for optimal health.
What’s more, this nutrient is particularly important for weight loss (
High protein intake can boost metabolism significantly while making you feel full enough to automatically eat fewer calories. It can also reduce cravings and your desire to snack late at night (
Doing aerobic exercise, also called cardio, is one of the best things you can do for your mental and physical health.
If you smoke or abuse drugs, tackle those problems first. Diet and exercise can wait.
If you drink alcohol, do so in moderation and consider avoiding it completely if you tend to drink too much.
Extra virgin olive oil is one of the healthiest vegetable oils.
Not all carbs are created equal.
Refined carbs have been highly processed to remove their fiber. They’re relatively low in nutrients and can harm your health when eaten in excess.
Saturated fat has been controversial.
While it’s true that saturated fat raises cholesterol levels, it also raises HDL (good) cholesterol and shrinks your LDL (bad) particles, which is linked to a lower risk of heart disease (
Lifting weights is one of the best things you can do to strengthen your muscles and improve your body composition.
The best approach is to lift weights, but doing bodyweight exercises can be just as effective.
While trans fats have been largely banned in the United States and elsewhere, the U.S. ban hasn’t gone fully into effect — and some foods still contain them.
Many incredibly healthy herbs and spices exist.
Due to their powerful benefits, you should try to include as many herbs and spices as possible in your diet.
Social relationships are incredibly important not only for your mental well-being but also your physical health.
The only way to know exactly how many calories you eat is to weigh your food and use a nutrition tracker.
It’s also essential to make sure that you’re getting enough protein, fiber, and micronutrients.
Studies reveal that people who track their food intake tend to be more successful at losing weight and sticking to a healthy diet (
Belly fat is particularly harmful.
For this reason, your waist size may be a much stronger marker of your health than your weight.
Diets are notoriously ineffective and rarely work well in the long term.
In fact, dieting is one of the strongest predictors for future weight gain (
Instead of going on a diet, try adopting a healthier lifestyle. Focus on nourishing your body instead of depriving it.
Weight loss should follow as you transition to whole, nutritious foods.
Whole eggs are so nutritious that they’re often termed “nature’s multivitamin.”
Additionally, a massive review in 263,938 people found that egg intake had no association with heart disease risk (
Instead, eggs are one of the planet’s most nutritious foods. Notably, the yolk contains almost all of the healthy compounds.
A few simple steps can go a long way toward improving your diet and wellness.
Still, if you’re trying to live a healthier life, don’t just focus on the foods you eat. Exercise, sleep, and social relationships are also important.
With the tips above, it’s easy to get your body feeling great every day.
