Top 10 Common Foods You Should Eat at the Right Time for Optimal Health

Milk is a favorite beverage for many, not just for children. It is rich in calcium, which helps strengthen teeth and bones, as well as improving the health of hair, nails, and skin. Milk also plays a key role in muscle development due to its high protein content and helps enhance skin appearance. While not a direct sleep aid, milk contains beneficial nutrients like calcium and vitamin B6 that contribute to better sleep by promoting serotonin production and improving sleep quality. Compared to other foods with the same calorie content, milk can make you feel fuller quicker, preventing hunger during the night that might disrupt your sleep. Therefore, milk is a great choice to consume in the evening before bed.

According to China's healthy eating guide, about 300 grams of milk per day is recommended, equivalent to 1.5 paper cups (disposable type). This is an average amount and does not mean you must drink exactly this amount daily. You can have 200 grams or 400 grams depending on your needs. For instance, if you can drink milk, you may consume it in the morning, evening, or night, or even have yogurt in the afternoon. All of these are fine, and there are no issues with drinking more or less. However, if you consume a lot of milk in a day—such as drinking milk, eating yogurt, and using powdered milk—it is important to reduce your intake of main meals and meats, as milk already provides a lot of protein. Without reducing protein from other foods, you could end up consuming excess energy, disrupting your nutritional balance.

Chestnuts, almonds, and walnuts are hard nuts rich in essential minerals and trace elements that are excellent for human health, especially for the cardiovascular system. According to a scientific study by Marshall University in Virginia, these nuts contain omega-3 fatty acids and antioxidants, making them powerful in preventing breast cancer and other types of cancer. Additionally, due to their fiber, protein, and healthy fat content, consuming these nuts regularly also aids in weight loss and diabetes prevention.

Like all plant-based foods, nuts provide a variety of nutrients, including healthy unsaturated fats, some protein, and many other nutrients like fiber, vitamins, minerals (calcium, iron, zinc, magnesium...). Each type of nut contains a unique balance of nutrients. Generally, one type of nut will have more prominent nutrients compared to others. It is recommended to consume 30g of mixed nuts daily, either as a snack or incorporated into other dishes. If you're not used to eating a particular type of nut, you can reduce its portion size.

Oranges are fruits rich in nutrients like vitamin C, citric acid, glucose, and can meet many of the basic needs of the human body. Aside from being nutritious, oranges offer several miraculous benefits if consumed correctly. Fresh oranges provide antioxidant vitamin C, which helps slow down cell aging and damage. In fact, vitamin C can boost your immune system. Additionally, consuming oranges reduces the risk of various cancers, blood-related diseases, joint problems, and boosts your immune resistance, protecting you from common illnesses like fever and colds.

Many people often ask: When is the best time to eat an orange? The optimal time is in the morning for better benefits. You can also drink orange juice when playing sports or exercising. Orange juice contains plenty of vitamin C, sugar, and essential nutrients that help support your exercise and recovery. So, drinking a glass of orange juice before and after exercise is excellent for your body. However, eating oranges on an empty stomach or just before meals can irritate your stomach due to the high sugar and acid content, causing discomfort. On the other hand, consuming oranges right after a meal can lead to fermentation in the stomach due to the sugar content, causing digestive discomfort.

Tomatoes are great for both health and beauty. They are packed with lycopene, a carotenoid with powerful antioxidant properties that can help prevent prostate and breast cancers. One tomato can provide up to 40% of the daily recommended intake of vitamin C. Additionally, tomatoes contain vitamin A, potassium, and iron, which support the nervous system and blood circulation. Many doctors recommend tomatoes for heart disease, kidney stones, digestive support, and lowering blood sugar. Properly consuming tomatoes can also counteract the harmful effects of smoking on the body. Furthermore, tomatoes are rich in vitamin A, making them great for pregnant women and children, as they help improve vision and are an excellent remedy for healthy teeth, bones, hair, and skin.

Although tomatoes are full of essential vitamins and nutrients, more isn't always better. Nutrition experts recommend that adults consume no more than 200g-300g of ripe tomatoes per day, which equals 2-3 tomatoes. For children, it’s best to limit their intake to 50g-100g of tomatoes per day, about 0.5-1 tomato. If you're using tomatoes for weight loss, it’s best to eat them at dinner or at night for the best results without affecting your health. After weight loss, continue eating tomatoes to avoid gaining weight back. Additionally, maintaining a habit of eating tomatoes at night can help break unhealthy eating habits after 7 p.m.

Rice is a staple food that is essential in every Vietnamese meal. However, did you know that eating too much rice at the wrong times can lead to weight gain? This is because rice is high in carbohydrates and starches, which generate a lot of energy, and this energy is difficult to burn off, often resulting in weight gain if consumed at the wrong time or in excess. To replace white rice, many people turn to alternatives with a lower glycemic index, such as brown rice, oats, or quinoa. However, these alternatives are often more expensive and not always readily available, and not everyone can completely replace white rice with these grains.

To determine the right portion size, doctors usually base it on your height, body type, weight, and daily activities. However, to simplify, a bowl of white rice typically equals 60g of starch. If you are a woman with a normal build and a light workload, one small serving of rice may suffice. For men, about 1.5 servings of rice is recommended, and if you do physical labor, you may increase your serving size by an additional half bowl per main meal. When eating a meal, it is advisable to prioritize vegetables and soup first. This helps you feel full, reducing your appetite, while the fiber in vegetables slows the absorption of starches, preventing rapid blood sugar spikes.

Few people pay attention to the benefits of fruits like figs and peaches, as they are not commonly sold in markets. However, these fruits are quite special, not only for their edible qualities but also for their medicinal uses. Some of the benefits of figs include: lowering blood pressure, promoting digestive health, preventing osteoporosis, and protecting against diabetes and cancer. As for peaches, they are rich in vitamins A, B, C, potassium, and other essential nutrients. These vitamins and minerals help improve skin health, prevent the growth of cancer cells, regulate bowel movements, relieve constipation, and prevent the proliferation of harmful bacteria in the body.

Peaches are also an excellent source of iron, along with protein, sugar, zinc, and pectin, making them beneficial for individuals suffering from anemia. Moreover, the pectin in peaches supports digestive health, reducing the risk of constipation. However, consuming too many peaches may not be good for your health, as it can lead to diarrhea and other digestive issues. It is recommended to eat no more than two peaches per day. While both figs and peaches are healthy fruits, excessive consumption of any one food can have adverse effects, and these fruits are no exception.

From a scientific perspective, cheese is not only a delightful treat for the taste buds but also provides significant health benefits. Cheese is rich in protein, calcium, fats, vitamins, and minerals. Nutrition experts agree that the nutrients found in cheese make it an excellent aid in weight loss. Additionally, cheese is packed with B vitamins and calcium, which help improve skin elasticity, slow down the aging process, enhance overall health, and strengthen bones.

However, since cheese is low in vitamin C, it is recommended to pair it with fresh fruits and vegetables. Also, it's best to limit cheese intake to about 25g per day due to its high sodium content. When buying block cheese, choose the one packaged in tin foil to preserve its quality. While cheese is generally healthy, some common misconceptions about its usage can not only diminish its natural flavor but also be detrimental to health. Moreover, cheese contains linoleic acid, a type of fat that helps prevent cancer, heart disease, and diabetes. Nutrition experts state that this substance can also prevent fat accumulation in the body.

Bananas are widely recognized as one of the healthiest and safest fruits you should eat daily. Packed with potassium and low in sodium, bananas help maintain stable blood pressure. According to recent research published in the "American Journal of Cardiology," scientists have found that consuming about 1,600 milligrams of potassium daily can reduce the risk of stroke by 20%. In addition to this, eating bananas has various other health benefits, including improving mood due to their vitamin B content, aiding digestion, promoting bowel regularity, reducing heartburn, boosting mental agility, reducing stress, and lowering stroke risk.

Bananas are especially good for children and the elderly, but it’s important to eat them in moderation. Since bananas are rich in potassium, consuming too many in a short time can result in excess potassium in the body, which may lead to irregular heart rhythms or temporary paralysis. Therefore, it's recommended to eat just 1-2 bananas per day. You can also replace ripe bananas with dried fruits, which retain their natural sweetness and high nutritional value. Always choose bananas from trusted, hygienic stores with clear sourcing to avoid any health issues.

Táo là loại trái cây quen thuộc trong cuộc sống hằng ngày và được nhiều người mua thường xuyên. Tuy nhiên, ít ai quan tâm đến khoảng thời gian ăn táo nào là tốt nhất cho cơ thể.

Mặc dù táo có tác dụng làm đẹp, giảm cân rất tốt nhưng nếu ăn trước khung giờ đi ngủ thì sẽ phản tác dụng.

Khoai tây là loại thực phẩm chứa rất nhiều vitamin: A, C, B... và các khoáng chất như phốt pho, canxi, sắt hay kali. Ngoài ra, một củ khoai tây còn rất giàu chất xơ và các protein. Nhờ đó, việc tiêu thụ khoai tây đúng thời điểm, đúng chừng mực sẽ có tác dụng trong việc giảm stress và nâng cao tinh thần đồng thời chống trầm cảm và ngừa ung thư cũng như giảm nguy cơ táo bón...

Khoai tây không chứa cholesterol, nhưng tùy thuộc vào cách nấu, bạn có thể vô tình “bổ sung” cholesterol vào khoai tây bằng cách chiên với dầu ăn. Cholesterol là loại chất béo cần thiết cho sự phát triển các tế bào khỏe mạnh. Tuy nhiên, quá nhiều cholesterol lại có thể gây xơ vữa động mạch, đau tim… Đôi khi, ăn khoai tây thực sự có thể gây tăng cân, đặc biệt nếu bạn chiên và ăn kèm với các thực phẩm giàu chất béo như phô mai.
