Healthy food and false beliefs FAQs

Find out the answers to the most commonly asked questions about healthy food and false beliefs

What is malnutrition?

Malnutrition is an abnormal condition caused by deficiencies, excesses or imbalances in energy and/or nutrients necessary for an active, healthy life. Therefore, it refers both to undernutrition and overnutrition, as well as to conditions arising from dietary imbalance leading to diet-related non-communicable diseases.

Waht is a healthy diet?

A healthy diet is a long-lasting behavior. There is not a single healthy diet that fits for all. Nutrition guidelines generally suggest that healthy diets are diverse, containing an appropriate amount of energy, fat and protein, as well as micronutrients from a combination of cereals, vegetables, fruits and animal-source foods. Dietary diversity—defined as the number of different food groups consumed over a given time period—is an indicator of a high-quality diet.

Who recommends that adults eat a mix of foods, with at least five portions of fruit and vegetables a day, less than 10% of total energy from free sugars added to foods, and less than 30% of total energy from fats, and that salt should be limited to less than 5 g (approximately 1 teaspoon) per day and it should be iodized. Advice on a healthy diet for infants and young children is similar, but these elements are also important. 

  • Infants should be breastfed exclusively for the first six months of life;
  • Infants should continue to be breastfed until two years of age and beyond;
  • From six months of age onwards, breast milk should be complemented with a variety of adequate, safe and nutrient-dense complementary foods. Salt and sugars should not be added to complementary foods.

What is the difference between food allergy and intolerance?

Food allergies and food intolerances (or sensitivities) can have similar symptoms, but are very different conditions:

  • Intolerances, such as lactose intolerance and celiac disease, can cause someone to feel ill.
  • Food allergies not only can make someone feel ill, but also can cause a life-threatening reaction (called anaphylaxis).

A food intolerance means either the body cannot properly digest the food that is eaten, or that a particular food might irritate the digestive system. Symptoms of food intolerance can include nausea, gas, cramps, abdominal pain, diarrhea, irritability, nervousness, or headaches.

A food allergy happens when the body's immune system, which normally fights infections, sees the food as an invader. This leads to an allergic reaction — a response from the immune system in which chemicals like histamine are released in the body. The reaction can cause symptoms like breathing problems, throat tightness, hoarseness, coughing, vomiting, abdominal pain, hives, swelling, or a drop in blood pressure.

Even if previous reactions have been mild, someone with a food allergy is always at risk of the next reaction being life-threatening. Eating a microscopic amount of the food, or sometimes even touching or inhaling it, could lead to anaphylaxis. So anyone with a food allergy must avoid the problem food.

It is true that cow’s milk is bad for your health?

Cow's milk is a daily staple for many people and has been for millennia. While it's still a popular food, recent studies suggest milk may have harmful effects on the body. Other research, however, points out the health benefits of dairy. So, what’s the truth? Let’s consider different foods as members a big variegated family, where each member has its own benefits and limits to be taken onto consideration.

Milk is considered a whole food. It provides 18 out of 22 essential nutrients.

Milk also provides: iron; selenium. Vitamin b-6, vitamin e, vitamin k, niacin, thiamin, riboflavin

Benefits of milk

  • Appetite control:  drinking milk hasn’t been linked to weight gain or obesity, and it may help curb appetite.
  • Bone development: milk may help improve weight and bone density in children, according to a 2016 study. It can also reduce the risk of fractures in developmental ages.
  • Milk provides proteins that are necessary to build and maintain healthy bones, teeth, and muscle. A cup of milk (250gr) provides around 7 to 8 grams of casein and whey proteins.
  • Bone and dental health: a cup of milk contains almost 30 percent (one/third) of the daily requirement of calcium for adults. Milk also contains potassium and magnesium. These minerals are important for healthy
  • Diabetes prevention: type 2 diabetes is a disease characterized by high blood sugar levels. Several studies have found that drinking milk may help prevent type 2 diabetes in adults. This may be because milk proteins improve your blood sugar balance. Additionally, milk is a good source of potassium. This mineral helps regulate blood pressure and it contains omega-3 fatty acids and conjugated linoleic acid. These fats help protect heart and blood vessel health.

Limits and possible side effects of milk

Allergies: up to 5 percent of children have a milk allergy, estimate some experts. It can cause skin reactions, such as eczema, and gut symptoms, such as: bowel effects: colic; constipation; diarrhea.

Other less common but specific reactions can include: anaphylaxis; wheezing; difficulty breathing.

Children may grow out of a milk allergy. Adults can also develop a milk allergy.

Lactose intolerance: cow's milk has a greater amount of lactose than milk from other animals.  Scientific studies estimate that 65-70 percent of the world's population has some form of lactose intolerance.
