Nutritional Intake: Addressing Oxalate Concerns and Healthy Fat Gain - Nutrition

Share to:

Nutritional intake


Hello, Nutritionist:
1.
For breakfast, I consume a smoothie made from bananas, plums, kiwis, peaches, and 7 slices of stone lotus (half a dragon fruit, lemon, apple, and guava).
I eat a more substantial lunch and skip dinner.
Could this amount of fruit lead to elevated oxalate levels? I am experiencing itchy skin, should I go to a lab for testing?
2.
My friend has a body fat percentage of only 7.5%.
He is male and wants to increase his fat intake to provide some cushioning for his organs.
What healthy options should he consider to increase his body fat?

Kevin, 10~19 year old female. Ask Date: 2009/06/18

Dr. Tang Weili reply Nutrition


Dear Kevin: For oxalic acid metabolism, drinking plenty of water daily (about 2000 cc/day, and more if sweating a lot) will help it be excreted through urine.
You can adjust your fruit intake accordingly.
If you are experiencing skin itching, please consult a physician.

Your friend is too thin and should consume more high-calorie foods: fried rice, fried noodles, and higher-fat dairy products like ice cream and milkshakes.
Daily caloric intake should reach 35-40 kcal per kilogram of body weight.

When it comes to nutritional intake, particularly regarding oxalate concerns and healthy fat gain, it’s essential to understand the implications of your dietary choices and how they affect your overall health.

1. Oxalate Concerns: You mentioned consuming a variety of fruits, including bananas, plums, kiwis, peaches, and a mix of other fruits in a smoothie. While fruits are generally healthy and provide essential vitamins and minerals, some fruits are higher in oxalates than others. Oxalates are naturally occurring compounds found in many plants, and for some individuals, particularly those prone to kidney stones, high oxalate intake can be a concern.
Bananas and kiwis are relatively low in oxalates, while fruits like plums and certain berries can have moderate levels. If you are experiencing skin itching, it could be due to various reasons, including allergies or sensitivities to certain foods, but it’s unlikely that the fruits you listed would cause a significant increase in oxalate levels unless consumed in excessive amounts. It’s advisable to consult with a healthcare provider or a registered dietitian who can help assess your symptoms and possibly recommend a urine test to measure oxalate levels if necessary.

2. Healthy Fat Gain: Regarding your friend with a body fat percentage of 7.5%, it’s important to note that while low body fat can be desirable for some, having too little body fat can pose health risks, including hormonal imbalances and decreased immune function. To achieve a healthy increase in body fat, your friend should focus on incorporating healthy fats into his diet.
Healthy fats can be found in foods such as avocados, nuts, seeds, olive oil, and fatty fish like salmon. These foods not only provide essential fatty acids but also contribute to overall caloric intake, which is crucial for gaining weight. For instance, adding a handful of nuts or a tablespoon of olive oil to meals can significantly increase caloric density without requiring large volumes of food.
Additionally, incorporating more complex carbohydrates, such as whole grains, legumes, and starchy vegetables, can help increase caloric intake while providing necessary nutrients. It’s also beneficial to include protein sources like lean meats, dairy, or plant-based proteins to support muscle growth and overall health.

In summary, while your fruit intake is generally healthy, monitoring for oxalate levels may be wise if you have specific health concerns. For your friend, focusing on healthy fats and balanced meals will help him achieve a healthier body fat percentage. It’s always best to consult with a healthcare professional or a registered dietitian for personalized advice tailored to individual health needs and goals.
